-From: Phillip Lougher <phillip@lougher.demon.co.uk>
-Date: Thu, 22 Oct 2009 04:57:38 +0100
-Subject: [PATCH] Squashfs: Make unlzma available to non initramfs/initrd code
-
-Add a config option DECOMPRESS_LZMA_NEEDED which allows subsystems to
-specify they need the unlzma code. Normally decompress_unlzma.c is
-compiled with __init and unlzma is not exported to modules.

-+AMBA standard fields like CID and PID.
-+
-+In case of Broadcom's cards every device consists of:
-+1) Broadcom specific AMBA device. It is put on AMBA bus, but can not be treated
-+ as standard AMBA device. Reading it's CID or PID can cause machine lockup.
-+2) AMBA standard devices called ports or wrappers. They have CIDs (AMBA_CID)
-+ and PIDs (0x103BB369), but we do not use that info for anything. One of that
-+ devices is used for managing Broadcom specific core.
-+
-+Addresses of AMBA devices are not hardcoded in driver and have to be read from
-+EPROM.
-+
-+In this situation we decided to introduce separated bus. It can contain up to
-+16 devices identified by Broadcom specific fields: manufacturer, id, revision
-+and class.

-This patch allows turning off the in-kernel Algorithmics
-FPU emulator support, which allows one to save a couple of
-precious blocks on an embedded system.

-GCC 4.4.x looks to be adding support for generating out-of-line register
-saves/restores based on:
-
-http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
-
-This breaks the kernel build as we'd have to link with libgcc to get the
-implementation of the register save/restores.
-
-To workaround this issue, we just stole the save/restore code from gcc
-and simplified it down for our needs (integer only). We only do this if
-PPC32 as gcc makes believe the linker on ppc64 will deal with this and
-only if CONFIG_CC_OPTIMIZE_FOR_SIZE is set (thus -Os).
-
-Signed-off-by: Kumar Gala <[EMAIL PROTECTED]>
----
-
-If someone using cutting edge toolchains for ppc64 could test and make
-sure if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE things work that would be
-nice.

-Subject: [PATCH] ext4: Use ext4 file system driver for ext2/ext3 file system mounts
-
-Add a new config option, CONFIG_EXT4_USE_FOR_EXT23 which if enabled,
-will cause ext4 to be used for either ext2 or ext3 file system mounts
-when ext2 or ext3 is not enabled in the configuration.
-
-This allows minimalist kernel fanatics to drop to file system drivers
-from their compiled kernel with out losing functionality.

-Subject: [PATCH] ext4: add module aliases for ext2 and ext3
-
-Add module aliases for ext2 and ext3 when CONFIG_EXT4_USE_FOR_EXT23 is
-set. This makes the existing user-space stuff like mkinitrd working
-as is.

-Subject: [PATCH] ARM: 5882/1: ARM: Fix uncompress code compile for different defines of flush(void)
-
-Because of the include of the decompress_inflate.c file from
-boot/compress/misc.c, there are different flush() defines:
-
-In file included from arch/arm/boot/compressed/misc.c:249:
-arch/arm/boot/compressed/../../../../lib/decompress_inflate.c:138:29: error: macro "flush" passed 2 arguments, but takes just 0
-
-Fix this by removing the define of flush() in misc.c for
-CONFIG_DEBUG_ICEDCC as it's already defined in mach/uncompress.h,
-and that is being included unconditionally.
-
-Also use a static inline function instead of define
-for mach-mxc and mach-gemini to avoid similar bug
-for those platforms.

-+ * Changed license from LGPL to GPL.
-+
-+2005-05-08 root <mk@mary>
-+
-+ * Makefile: clean it up and added make install and make
-+ uninstall.
-+
-+2005-05-06 <mk@mary>
-+
-+ * merged devel branch back to main. [v0-6-0-pre3]
-+
-+ * removed unused files print.c and fist_ioctl. [devel-0-0-18]
-+
-+ * ioctl: removed fist_ioctl stuff, that is not needed for
-+ now.
-+
-+2005-05-03 <mk@mary>
-+
-+ * file.c: simplified mini_fo_open and mini_fo_setattr using
-+ new state changing functions. [devel-0-0-17]
-+
-+ * inode.c: Fixed getattr state bug (see below) in 2.4 function
-+ mini_fo_inode revalidate.
-+
-+ * inode.c: found an other bug in mini_fo_getattr. States are not
-+ reliable in this function, as a file can be opened, unlinked and
-+ the getattr function called. This results in a deleted dentry
-+ with an inode. Fix is to ignore states and simply use the inode
-+ available.
-+
-+2005-04-29 <mk@mary>
-+
-+ * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
-+
-+ * file.c: do not use mini_fo_lock so the generic version is
-+ used (I guess).
-+
-+ * inode.c: getattr, never call getattr on lower files, as this
-+ will cause the inum to change.
-+
-+ * inode.c: rename_reg_file renamed to rename_nondir, as it
-+ doesn't matter as long it't not a dir. Removed all
-+ rename_dev_file etc.
-+
-+ * tagged as devel-0-0-15
-+
-+ * inode.c: added support for chosing support for extended
-+ attrs at compile time by XATTR define in mini_fo.h .
-+
-+ * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
-+ lower again, what avoids inode number changes that confused
-+ rm again. This is the proper solution.
-+
-+2005-04-24 <mk@mary>
-+
-+ * all files: updated Copyright notive to 2005. [devel-0-0-14]
-+
-+ * inode.c: fixed mini_fo_getattr to not change the inode
-+ number, even if lower files change.
-+
-+ * super.c: fixed a bug that caused deleted base file to show
-+ up suddenly after some time, or after creating a special
-+ file. The problem was that after some time or after special
-+ file creating sync_sb_inodes is called by the vfs, that
-+ called our mini_fo_put_inode. There was (wrongly) called
-+ __meta_put_lists, that nuked the lists, although the inode
-+ was going to continue its life. Moving __meta_put_lists to
-+ mini_fo_clear_inode, where an inode is really destroyed,
-+ solved the problem.
-+
-+
-+2005-04-23 <mk@mary>
-+
-+ * state.c, aux.c: more cleaning up and
-+ simplifications. [devel-0-0-13]
-+
-+ * inode.c: implemented mini_fo_getattr, that was required for
-+ 2.6 because inode_revalidate has been remove there, and the
-+ old "du" bug returned.
-+
-+
-+2005-04-20 <mk@mary>
-+
-+ * aux.c: get_neg_sto_dentry(): allow to be called for dentries
-+ in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
-+
-+2005-04-19 <mk@mary>
-+
-+ * Fixed a bug under 2.6 that caused files deleted via mini_fo
-+ not to be deleted properly and therefore the fs filled up
-+ untill no memory was left. [devel-0-0-12]
-+
-+ * Added basic hard link support. This means that creating
-+ hardlinks will work, but existing ones will be treated as
-+ individual files. [devel-0-0-11]
-+
-+2005-04-17 <mk@mary>
-+
-+ * Bugfixes
-+
-+2005-04-13 root <mk@mary>
-+
-+ * Added file state.c for the state transition
-+ functions. Doesn't work very well yet, though...
-+
-+2005-04-12 <mk@mary>
-+
-+ * Porting to 2.6 started, which is easier than expected, also
-+ due to Olivier previous work.
-+
-+2005-04-08 <mk@mary>
-+
-+ * Fixed the bug that caused du to return invalid sizes of
-+ directory trees. The problem was that
-+ mini_fo_inode_revalidate didn't always copy the attributes
-+ from the base inode properly.
-+
-+2005-04-01 Markus Klotzbuecher <mk@chasey>
-+
-+ * Merged devel branch back to main trunk and updated the
-+ RELEASE notes. This will be 0-6-0-pre1.
-+
-+2005-03-31 Markus Klotzbuecher <mk@chasey>
-+
-+ * Fixed some bugs in rename_reg_file, that only showed up in
-+ the kernel compile test. Kernel compiles cleanly ontop of
-+ mini_fo, now also make mrproper etc. work. Seems pretty stable.
-+
-+2005-03-28 Markus Klotzbuecher <mk@chasey>
-+
-+ * Many, many directory renaming bugfixes and a lot of other
-+ cleanup. Dir renaming seems to work relatively stable.
-+
-+2005-03-22 Markus Klotzbuecher <mk@chasey>
-+
-+ * Finished implementing lightweight directory renaming. Some
-+ basic testing indicates it works fine.
-+ Next is to implement testcases for the testsuite and confirm
-+ everything is really working ok.
-+
-+2005-03-18 Markus Klotzbuecher <mk@chasey>
-+
-+ * Finished implementing meta.c stuff required for directory
-+ renaming.
-+
-+2005-03-17 Markus Klotzbuecher <mk@chasey>
-+
-+ * Fixed all compile warnings + an extremly old bug that
-+ somehow crept in while reworking the wol stuff to the META
-+ system. Turning on -Werror again... :-)
-+
-+ * Fixed some bugs in the new rename_reg_file function.
-+
-+ * Rewrote mini_fo rename and split it into several
-+ subfunctions, that handle the different types
-+ seperately. Rewrote the regular file function aswell, as it
-+ was implemented somewhat inefficient.
-+
-+2005-03-16 Markus Klotzbuecher <mk@chasey>
-+
-+ * Implemented new META subsystem, removed old WOL stuff in favor
-+ if it.
-+
-+ * After some basic testing everything seems ok...
-+
-+2005-03-11 Markus Klotzbuecher <mk@chasey>
-+
-+ * Renaming a non regular file caused trouble because I always
-+ tried to copy the contents. Now I only do this for regular
-+ files. mini_fo_rename still isn't implemented properly, renaming
-+ of device files, symlinks etc. results in a empty regular file
-+ instead of the proper type.
-+
-+ * Directory renaming suddenly works! What a surprise! I guess
-+ this is because renaming is implemented as making a copy and
-+ removing the original. Still this might not work
-+ everywhere...
-+
-+2005-03-09 Markus Klotzbuecher <mk@chasey>
-+
-+ * Bugfix, when a mini_fo directory that exists in storage
-+ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
-+ possibly existing WOL file contained in it needs to be
-+ deleted too.
-+
-+ * Starting cleanup: defined state names in order to get rid of
-+ the state numbers.
-+
-+2005-03-08 Markus Klotzbuecher <mk@chasey>
-+
-+ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
-+
-+ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
-+ DEL_REWRITTEN the hash was calculated from the base dentry,
-+ which was wrong and and caused assertions in
-+ __mini_fo_hidden_dentry to fail.
-+
-+2005-02-21 <mk@mary>
-+
-+ * Implemented directory deleting (inode.c)
-+
-+ * main.c: made mini_fo_parse_options a little more robust.
-+
-+2004-12-22 <mk@mary>
-+
-+ * Makefile cleanup and uml stuff, removed unneccessary files
-+
-+ * Created a new and hopefully more informative README
-+
-+ * CHANGELOG: created a new CHANGELOG and added old entries reversely
-+
-+
-+2004-10-24 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Fix: owner and group where not correctly copied from base to
-+ storage.
-+
-+
-+2004-10-05 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Implementation of fsync, fasync and lock mini_fo functions.
-+
-+
-+2004-09-29 Bob Lee <bob@pantasys.com>
-+
-+ * Fix of a serious pointer bug
-+
-+
-+2004-09-28 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Implementation of mini_fo_mknod and mini_fo_rename, support
-+ for device files.

-+Version 0.1
-+
-+This script overlays the given base directory using the mini_fo file
-+system. If only the base directory base_dir is given, $0
-+will use a storage directory called "sto-<base_dir_name>" in $STO_DIR,
-+and mount point "mini_fo-<base_dir_dir>" in $MNT_DIR.
-+
-+Options:
-+ -s <suffix>
-+ add given suffix to storage directory and the mount
-+ point. This is usefull for overlaying one base directory
-+ several times and avoiding conflicts with storage directory
-+ names and mount points.
-+
-+ -d <sto_dir_dir>
-+ change the directory in which the storage directory will be
-+ created (default is currently "$STO_DIR".
-+
-+ -m <mount point>
-+ use an alternative directory to create the mini_fo
-+ mountpoint (default is currently "$MNT_DIR".
-+

-+README for the mini_fo overlay file system
-+=========================================
-+
-+
-+WHAT IS MINI_FO?
-+----------------
-+
-+mini_fo is a virtual kernel file system that can make read-only
-+file systems writable. This is done by redirecting modifying operations
-+to a writeable location called "storage directory", and leaving the
-+original data in the "base directory" untouched. When reading, the
-+file system merges the modifed and original data so that only the
-+newest versions will appear. This occurs transparently to the user,
-+who can access the data like on any other read-write file system.
-+
-+Base and storage directories may be located on the same or on
-+different partitions and may be of different file system types. While
-+the storage directory obviously needs to be writable, the base may or
-+may not be writable, what doesn't matter as it will no be modified
-+anyway.
-+
-+
-+WHAT IS GOOD FOR?
-+-----------------
-+
-+The primary purpose of the mini_fo file system is to allow easy
-+software updates to embedded systems, that often store their root
-+file system in a read-only flash file system, but there are many
-+more as for example sandboxing, or for allowing live-cds to
-+permanently store information.
-+
-+
-+BUILDING
-+--------
-+This should be simple. Adjust the Makefile to point to the correct
-+kernel headers you want to build the module for. Then:
-+
-+ # make
-+
-+should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
-+kernel.
-+
-+If you are building the module for you current kernel, you can install
-+the module (as root):
-+
-+ # make install
-+
-+or uninstall with
-+
-+ # make uninstall
-+
-+
-+USING THE FILE SYSTEM
-+--------------------
-+
-+the general mount syntax is:
-+
-+ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
-+ <base directory> <mount point>
-+
-+Example:
-+
-+You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
-+on it:
-+
-+load the module (as root)
-+
-+ # insmod mini_fo.o for a 2.4 kernel or
-+
-+ # insmod mini_fo.ko for a 2.6 kernel
-+
-+
-+create a storage dir in tmp and a mountpoint for mini_fo:
-+
-+ # mkdir /tmp/sto
-+ # mkdir /mnt/mini_fo
-+
-+and mount the mini_fo file system:
-+
-+ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
-+
-+
-+Now the data stored on the cd can be accessed via the mini_fo
-+mountpoint just like any read-write file system, files can be modified
-+and deleted, new ones can be created and so on. When done unmount the
-+file system:
-+
-+ # unmount /mnt/mini_fo
-+
-+Note that if the file system is mounted again using the same storage
-+file system, of course it will appear in the modified state again. If
-+you remount it using an new empty storage directory, it will be
-+unmodified. Therefore by executing:
-+
-+ # cd /tmp/sto
-+ # rm -rf *
-+
-+you can nuke all the changes you made to the original file system. But
-+ remember NEVER do this while the mini_fo file system is mounted!
-+
-+
-+Alternatively you can use the mini_fo-overlay bash script, that
-+simplifies managing mini_fo mounts. See TOOLS Section.
-+
-+
-+TOOLS
-+-----
-+
-+mini_fo-merge (experimental):
-+
-+This is a bash script that will merge changes contained in the storage
-+directory back to the base directory. This allows mini_fo to function
-+as a cache file system by overlaying a slow (network, ...) file system
-+and using a fast (ramdisk, ...) as storage. When done, changes can be
-+merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
-+-h" for details.
-+
-+It can be usefull for merging changes back after a successfull test
-+(patches, software updates...)
-+
-+
-+mini_fo-overlay:
-+
-+This bash script simplifies managing one or more mini_fo mounts. For
-+overlaying a directory called "basedir1", you can just call:
-+
-+ # mini_fo-overlay basedir1
-+
-+This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
-+as storage to "/mnt/mini_fo-basedir1/". It has more options though,
-+type "mini_fo-overlay -h" for details.
-+
-+
-+DOCUMENTATION, REPORTING BUGS, GETTING HELP
-+-------------------------------------------
-+
-+Please visit the mini_fo project page at:
-+
-+http://www.denx.de/twiki/bin/view/Know/MiniFOHome
-+
-+
-+WARNINGS
-+--------
-+
-+Never modify the base or the storage directorys while the mini_fo
-+file system is mounted, or you might crash you system. Simply accessing
-+and reading should not cause any trouble.
-+
-+Exporting a mini_fo mount point via NFS has not been tested, and may
-+or may not work.
-+
-+Check the RELEASE_NOTES for details on bugs and features.

-+Release: mini_fo-0.6.1 (v0-6-1)
-+Date: 21.09.2005
-+
-+
-+Changes:
-+--------
-+v0-6-1:
-+
-+- bugfixes (see ChangeLog)
-+
-+- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
-+ README for details).
-+
-+v0-6-0:
-+
-+- Support for 2.4 and 2.6 (see Makefile)
-+
-+- Partial hard link support (creating works as expected, but already
-+ existing links in the base file system will be treated as if they
-+ were individual files).
-+
-+- Various bugfixes and cleanups.
-+
-+
-+v0-6-0-pre1:
-+
-+- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
-+ many vital mini_fo parts such as the old whiteout list code which
-+ has been replaced by the new META subsystem.
-+
-+- Light weight directory renaming implemented. This means if a
-+ directory is renamed via the mini_fo filesystem this will no longer
-+ result in a complete copy in storage, instead only one empty
-+ directory will be created. All base filed contained in the original
-+ directory stay there until modified.
-+
-+- Special files (creating, renaming, deleting etc.) now working.
-+
-+- Many bugfixes and cleanup, mini_fo is now a lot more stable.
-+
-+
-+v0-5-10:
-+
-+- Final release of the 0-5-* versions. Next will be a complete rewrite
-+ of many features. This release contains several bugfixes related to
-+ directory renaming.
-+
-+
-+v0-5-10-pre6:
-+
-+- Lots of cleanup and several bugfixes related to directory deleting
-+
-+- Directory renaming suddenly works, what is most likely due to the
-+ fact tha that "mv" is smart: if the classic rename doesn't work it
-+ will assume that source and target file are on different fs and will
-+ copy the directory and try to remove the source directory. Until
-+ directory removing wasn't implemented, it would fail to do this and
-+ rollback.
-+ So, directory renaming works for now, but it doesn't yet do what you
-+ would expect from a overlay fs, so use with care.
-+
-+
-+v0-5-10-pre5:
-+
-+- implemented directory deleting
-+- made parsing of mount options more stable
-+- New format of mount options! (See README)
-+- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
-+ happily assume it never existed!
-+
-+
-+Implemented features:
-+---------------------
-+
-+- creating hard links (see BUGS on already existing hard links)
-+- lightweight directory renaming
-+- renaming device files, pipes, sockets, etc.
-+- creating, renaming, deleting of special files
-+- deleting directorys
-+- general directory reading (simple "ls" )
-+- creating files in existing directorys
-+- creating directorys
-+- renaming files.
-+- reading and writing files (involves opening)
-+- appending to files (creates copy in storage)
-+- deleting files
-+- llseek works too, what allows editors to work
-+- persistency (a deleted file stay deleted over remounts)
-+- use of symbolic links
-+- creating of device files
-+
-+
-+Not (yet) implemented features:
-+-------------------------------
-+
-+- full hard link support.
-+
-+
-+
-+BUGS:
-+-----
-+
-+Hard links in the base file system will be treated as individual
-+files, not as links to one inode.
-+
-+The main problem with hard links isn't allowing to create them, but
-+their pure existence. If you modify a base hard link, the changes made
-+will only show up on this link, the other link will remain in the
-+original state. I hope to fix this someday. Please note that this does
-+not effect the special hard links '.' and '..', that are handled
-+seperately by the lower fs.

-- help
-- Give the number of Blocks to reserve for checkpointing.
-- Checkpointing saves the state at unmount so that mounting is
-- much faster as a scan of all the flash to regenerate this state
-- is not needed. These Blocks are reserved per partition, so if
-- you have very small partitions the default (10) may be a mess
-- for you. You can set this value to 0, but that does not mean
-- checkpointing is disabled at all. There only won't be any
-- specially reserved blocks for checkpointing, so if there is
-- enough free space on the filesystem, it will be used for
-- checkpointing.
--
-- If unsure, leave at default (10), but don't wonder if there are
-- always 2MB used on your large page device partition (10 x 2k
-- pagesize). When using small partitions or when being very small
-- on space, you probably want to set this to zero.

-Subject: [PATCH] spi/mmc_spi: SPI bus locking API, using mutex
-
-SPI bus locking API to allow exclusive access to the SPI bus, especially, but
-not limited to, for the mmc_spi driver.
-
-Coded according to an outline from Grant Likely; here is his
-specification (accidentally swapped function names corrected):
-
-It requires 3 things to be added to struct spi_master.
-- 1 Mutex
-- 1 spin lock
-- 1 flag.
-
-The mutex protects spi_sync, and provides sleeping "for free"
-The spinlock protects the atomic spi_async call.
-The flag is set when the lock is obtained, and checked while holding
-the spinlock in spi_async(). If the flag is checked, then spi_async()
-must fail immediately.
-
-The current runtime API looks like this:
-spi_async(struct spi_device*, struct spi_message*);
-spi_sync(struct spi_device*, struct spi_message*);
-
-The API needs to be extended to this:
-spi_async(struct spi_device*, struct spi_message*)
-spi_sync(struct spi_device*, struct spi_message*)
-spi_bus_lock(struct spi_master*) /* although struct spi_device* might
-be easier */
-spi_bus_unlock(struct spi_master*)
-spi_async_locked(struct spi_device*, struct spi_message*)
-spi_sync_locked(struct spi_device*, struct spi_message*)
-
-Drivers can only call the last two if they already hold the spi_master_lock().
-
-spi_bus_lock() obtains the mutex, obtains the spin lock, sets the
-flag, and releases the spin lock before returning. It doesn't even
-need to sleep while waiting for "in-flight" spi_transactions to
-complete because its purpose is to guarantee no additional
-transactions are added. It does not guarantee that the bus is idle.
-
-spi_bus_unlock() clears the flag and releases the mutex, which will
-wake up any waiters.
-
-The difference between spi_async() and spi_async_locked() is that the
-locked version bypasses the check of the lock flag. Both versions
-need to obtain the spinlock.
-
-The difference between spi_sync() and spi_sync_locked() is that
-spi_sync() must hold the mutex while enqueuing a new transfer.
-spi_sync_locked() doesn't because the mutex is already held. Note
-however that spi_sync must *not* continue to hold the mutex while
-waiting for the transfer to complete, otherwise only one transfer
-could be queued up at a time!
-
-Almost no code needs to be written. The current spi_async() and
-spi_sync() can probably be renamed to __spi_async() and __spi_sync()
-so that spi_async(), spi_sync(), spi_async_locked() and
-spi_sync_locked() can just become wrappers around the common code.
-
-spi_sync() is protected by a mutex because it can sleep
-spi_async() needs to be protected with a flag and a spinlock because
-it can be called atomically and must not sleep

-From: Ernst Schwab <eschwab@online.de>
-Date: Thu, 18 Feb 2010 12:47:46 +0100
-Subject: [PATCH] spi/mmc_spi: mmc_spi adaptations for SPI bus locking API
-
-Modification of the mmc_spi driver to use the SPI bus locking API.
-With this, the mmc_spi driver can be used together with other SPI
-devices on the same SPI bus. The exclusive access to the SPI bus is
-now managed in the SPI layer. The counting of chip selects in the probe
-function is no longer needed.

-+GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
-+================================================================
-+
-+The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
-+MMC or SD card on GPIO pins.
-+
-+Two interfaces for registering a new MMC/SD card device are provided:
-+A static platform-device based mechanism and a dynamic configfs based interface.
-+
-+
-+Registering devices via platform-device
-+=======================================
-+
-+The platform-device interface is used for registering MMC/SD devices that are
-+part of the hardware platform. This is most useful only for embedded machines
-+with MMC/SD devices statically connected to the platform GPIO bus.
-+
-+The data structures are declared in <linux/mmc/gpiommc.h>.
-+
-+To register a new device, define an instance of struct gpiommc_platform_data.
-+This structure holds any information about how the device is hooked up to the
-+GPIO pins and what hardware modes the device supports. See the docbook-style
-+documentation in the header file for more information on the struct fields.
-+
-+Then allocate a new instance of a platform device by doing:
-+
-+ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
-+
-+This will allocate the platform device data structures and hook it up to the
-+gpiommc driver.
-+Then add the gpiommc_platform_data to the platform device.
-+
-+ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
-+
-+You may free the local instance of struct gpiommc_platform_data now. (So the
-+struct may be allocated on the stack, too).
-+Now simply register the platform device.
-+
-+ err = platform_device_add(pdev);
-+
-+Done. The gpiommc probe routine will be invoked now and you should see a kernel
-+log message for the added device.
-+
-+
-+Registering devices via configfs
-+================================
-+
-+MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
-+selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
-+hardware are a common situation.
-+So we provide a dynamic interface to conveniently handle adding and removing
-+devices from userspace, without the need to recompile the kernel.
-+
-+The "gpiommc" subdirectory at the configfs mountpoint is used for handling
-+the dynamic configuration.
-+
-+To create a new device, it must first be allocated with mkdir.
-+The following command will allocate a device named "my_mmc":
-+ mkdir /config/gpiommc/my_mmc
-+
-+There are several configuration files available in the new
-+/config/gpiommc/my_mmc/ directory:
-+
-+gpio_data_in = The SPI data-IN GPIO pin number.
-+gpio_data_out = The SPI data-OUT GPIO pin number.
-+gpio_clock = The SPI Clock GPIO pin number.
-+gpio_chipselect = The SPI Chipselect GPIO pin number.
-+gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
-+ If 1, Chipselect is active-LOW.
-+spi_mode = The SPI data mode. Can be 0-3.
-+spi_delay = Enable all delays in the lowlevel bitbanging.
-+max_bus_speed = The maximum SPI bus speed. In Hertz.
-+
-+register = Not a configuration parameter.
-+ Used to register the configured card
-+ with the kernel.
-+
-+The device must first get configured and then registered by writing "1" to
-+the "register" file.
-+The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
-+and "gpio_chipselect" are essential and _must_ be configured before writing
-+"1" to the "register" file. The registration will fail, otherwise.
-+
-+The default values for the other parameters are:
-+gpio_chipselect_activelow = 1 (CS active-LOW)
-+spi_mode = 0 (SPI_MODE_0)
-+spi_delay = 1 (enabled)
-+max_bus_speed = 5000000 (5 Mhz)
-+
-+Configuration values can not be changed after registration. To unregister
-+the device, write a "0" to the "register" file. The configuration can be
-+changed again after unregistering.
-+
-+To completely remove the device, simply rmdir the directory
-+(/config/gpiommc/my_mmc in this example).
-+There's no need to first unregister the device before removing it. That will
-+be done automatically.
