-Subject: [PATCH 054/454] BCM2708: Add core Device Tree support
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add the bare minimum needed to boot BCM2708 from a Device Tree.

-
-BCM2708: DT: change 'axi' nodename to 'soc'
-
-Change DT node named 'axi' to 'soc' so it matches ARCH_BCM2835.
-The VC4 bootloader fills in certain properties in the 'axi' subtree,
-but since this is part of an upstreaming effort, the name is changed.

-
-BCM2708_DT: Correct length of the peripheral space
-
-Use dts-dirs feature for overlays.
-
-The kernel makefiles have a dts-dirs target that is for vendor subdirectories.
-
-Using this fixes the install_dtbs target, which previously did not install the overlays.
-
-BCM270X_DT: configure I2S DMA channels

-
-BCM270X_DT: switch to bcm2835-i2s
-
-I2S soundcard drivers with proper devicetree support (i.e. not linking
-to the cpu_dai/platform via name but to cpu/platform via of_node)
-will work out of the box without any modifications.
-
-When the kernel is compiled without devicetree support the platform
-code will instantiate the bcm2708-i2s driver and I2S soundcard drivers
-will link to it via name, as before.

-SDIO-overlay: add poll_once-boolean parameter
-
-Add paramter to toggle sdio-device-polling
-done every second or once at boot-time.

-
-BCM270X_DT: Make mmc overlay compatible with current firmware
-
-The original DT overlay logic followed a merge-then-patch procedure,
-i.e. parameters are applied to the loaded overlay before the overlay
-is merged into the base DTB. This sequence has been changed to
-patch-then-merge, in order to support parameterised node names, and
-to protect against bad overlays. As a result, overrides (parameters)
-must only target labels in the overlay, but the overlay can obviously target nodes in the base DTB.
-
-mmc-overlay.dts (that switches back to the original mmc sdcard
-driver) is the only overlay violating that rule, and this patch
-fixes it.
-
-bcm270x_dt: Use the sdhost MMC controller by default
-
-The "mmc" overlay reverts to using the other controller.
-
-squash: Add cprman to dt
-
-BCM270X_DT: Use clk_core for I2C interfaces
-
-BCM270X_DT: Use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi
-
-The mainline Device Tree files are quite close to downstream now.
-Let's use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi as base files
-for our dts files.
-
-Mainline dts files are based on these files:
-
- bcm2835-rpi.dtsi
- bcm2835.dtsi bcm2836.dtsi
- bcm283x.dtsi
-
-Current downstream are based on these:
-
- bcm2708.dtsi bcm2709.dtsi bcm2710.dtsi
- bcm2708_common.dtsi
-
-This patch introduces this dependency:
-
- bcm2708.dtsi bcm2709.dtsi
- bcm2708-rpi.dtsi
- bcm270x.dtsi
- bcm2835.dtsi bcm2836.dtsi
- bcm283x.dtsi
-
-And:
- bcm2710.dtsi
- bcm2708-rpi.dtsi
- bcm270x.dtsi
- bcm283x.dtsi
-
-bcm270x.dtsi contains the downstream bcm283x.dtsi diff.
-bcm2708-rpi.dtsi is the downstream version of bcm2835-rpi.dtsi.
-
-Other changes:
-- The led node has moved from /soc/leds to /leds. This is not a problem
- since the label is used to reference it.
-- The clk_osc reg property changes from 6 to 3.
-- The gpu nodes has their interrupt property set in the base file.
-- the clocks label does not point to the /clocks node anymore, but
- points to the cprman node. This is not a problem since the overlays
- that use the clock node refer to it directly: target-path = "/clocks";
-- some nodes now have 2 labels since mainline and downstream differs in
- this respect: cprman/clocks, spi0/spi, gpu/vc4.
-- some nodes doesn't have an explicit status = "okay" since they're not
- disabled in the base file: watchdog and random.
-- gpiomem doesn't need an explicit status = "okay".
-- bcm2708-rpi-cm.dts got the hpd-gpios property from bcm2708_common.dtsi,
- it's now set directly in that file.
-- bcm2709-rpi-2-b.dts has the timer node moved from /soc/timer to /timer.
-- Removed clock-frequency property on the bcm{2709,2710}.dtsi timer nodes.

-BCM270X_DT: Add a .dtbo target, use for overlays
-
-Change the filenames and extensions to keep the pre-DDT style of

-platforms.
-
-The RPi firmware uses the DDTK trailer atom to choose which type of

-BCM270X_DT: Don't generate "linux,phandle" props
-
-The EPAPR standard says to use "phandle" properties to store phandles,
-rather than the deprecated "linux,phandle" version. By default, dtc
-generates both, but adding "-H epapr" causes it to only generate
-"phandle"s, saving some space and clutter.

-BCM270X_DT: Add midi-uart0 overlay
-
-MIDI requires 31.25kbaud, a baudrate unsupported by Linux. The
-midi-uart0 overlay configures uart0 (ttyAMA0) to use a fake clock
-so that requesting 38.4kbaud actually gets 31.25kbaud.

-+Introduction
-+============
-+
-+This directory contains Device Tree overlays. Device Tree makes it possible
-+to support many hardware configurations with a single kernel and without the
-+need to explicitly load or blacklist kernel modules. Note that this isn't a
-+"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices
-+are still configured by the board support code, but the intention is to
-+eventually reach that goal.
-+
-+On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By
-+default, the Raspberry Pi kernel boots with device tree enabled. You can
-+completely disable DT usage (for now) by adding:
-+
-+ device_tree=
-+
-+to your config.txt, which should cause your Pi to revert to the old way of
-+doing things after a reboot.
-+
-+In /boot you will find a .dtb for each base platform. This describes the
-+hardware that is part of the Raspberry Pi board. The loader (start.elf and its
-+siblings) selects the .dtb file appropriate for the platform by name, and reads
-+it into memory. At this point, all of the optional interfaces (i2c, i2s, spi)
-+are disabled, but they can be enabled using Device Tree parameters:
-+
-+ dtparam=i2c=on,i2s=on,spi=on
-+
-+However, this shouldn't be necessary in many use cases because loading an
-+overlay that requires one of those interfaces will cause it to be enabled
-+automatically, and it is advisable to only enable interfaces if they are
-+needed.
-+
-+Configuring additional, optional hardware is done using Device Tree overlays
-+(see below).
-+
-+GPIO numbering uses the hardware pin numbering scheme (aka BCM scheme) and
-+not the physical pin numbers.
-+
-+raspi-config
-+============
-+
-+The Advanced Options section of the raspi-config utility can enable and disable
-+Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it
-+is possible to both enable an interface and blacklist the driver, if for some
-+reason you should want to defer the loading.
-+
-+Modules
-+=======
-+
-+As well as describing the hardware, Device Tree also gives enough information
-+to allow suitable driver modules to be located and loaded, with the corollary
-+that unneeded modules are not loaded. As a result it should be possible to
-+remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can
-+have its contents deleted (or commented out).
-+
-+Using Overlays
-+==============
-+
-+Overlays are loaded using the "dtoverlay" directive. As an example, consider
-+the popular lirc-rpi module, the Linux Infrared Remote Control driver. In the
-+pre-DT world this would be loaded from /etc/modules, with an explicit
-+"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled,
-+this becomes a line in config.txt:
-+
-+ dtoverlay=lirc-rpi
-+
-+This causes the file /boot/overlays/lirc-rpi.dtbo to be loaded. By
-+default it will use GPIOs 17 (out) and 18 (in), but this can be modified using
-+DT parameters:
-+
-+ dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13
-+
-+Parameters always have default values, although in some cases (e.g. "w1-gpio")
-+it is necessary to provided multiple overlays in order to get the desired
-+behaviour. See the list of overlays below for a description of the parameters
-+and their defaults.
-+
-+The Overlay and Parameter Reference
-+===================================
-+
-+N.B. When editing this file, please preserve the indentation levels to make it
-+simple to parse programmatically. NO HARD TABS.
-+
-+
-+Name: <The base DTB>
-+Info: Configures the base Raspberry Pi hardware
-+Load: <loaded automatically>
-+Params:
-+ audio Set to "on" to enable the onboard ALSA audio
-+ interface (default "off")
-+
-+ i2c_arm Set to "on" to enable the ARM's i2c interface
-+ (default "off")
-+
-+ i2c_vc Set to "on" to enable the i2c interface
-+ usually reserved for the VideoCore processor
-+ (default "off")
-+
-+ i2c An alias for i2c_arm
-+
-+ i2c_arm_baudrate Set the baudrate of the ARM's i2c interface
-+ (default "100000")
-+
-+ i2c_vc_baudrate Set the baudrate of the VideoCore i2c interface
-+ (default "100000")
-+
-+ i2c_baudrate An alias for i2c_arm_baudrate
-+
-+ i2s Set to "on" to enable the i2s interface
-+ (default "off")
-+
-+ spi Set to "on" to enable the spi interfaces
-+ (default "off")
-+
-+ random Set to "on" to enable the hardware random
-+ number generator (default "on")
-+
-+ sd_overclock Clock (in MHz) to use when the MMC framework
-+ requests 50MHz
-+
-+ sd_force_pio Disable DMA support for SD driver (default off)
-+
-+ sd_pio_limit Number of blocks above which to use DMA for
-+ SD card (default 1)
-+
-+ sd_debug Enable debug output from SD driver (default off)
-+
-+ uart0 Set to "off" to disable uart0 (default "on")
-+
-+ uart1 Set to "on" or "off" to enable or disable uart1
-+ (default varies)
-+
-+ watchdog Set to "on" to enable the hardware watchdog
-+ (default "off")
-+
-+ act_led_trigger Choose which activity the LED tracks.
-+ Use "heartbeat" for a nice load indicator.
-+ (default "mmc")
-+
-+ act_led_activelow Set to "on" to invert the sense of the LED
-+ (default "off")
-+ N.B. For Pi3 see pi3-act-led overlay.
-+
-+ act_led_gpio Set which GPIO to use for the activity LED
-+ (in case you want to connect it to an external
-+ device)
-+ (default "16" on a non-Plus board, "47" on a
-+ Plus or Pi 2)
-+ N.B. For Pi3 see pi3-act-led overlay.
-+
-+ pwr_led_trigger
-+ pwr_led_activelow
-+ pwr_led_gpio
-+ As for act_led_*, but using the PWR LED.
-+ Not available on Model A/B boards.
-+
-+ N.B. It is recommended to only enable those interfaces that are needed.
-+ Leaving all interfaces enabled can lead to unwanted behaviour (i2c_vc
-+ interfering with Pi Camera, I2S and SPI hogging GPIO pins, etc.)
-+ Note also that i2c, i2c_arm and i2c_vc are aliases for the physical
-+ interfaces i2c0 and i2c1. Use of the numeric variants is still possible
-+ but deprecated because the ARM/VC assignments differ between board
-+ revisions. The same board-specific mapping applies to i2c_baudrate,
-+ and the other i2c baudrate parameters.

-+Troubleshooting
-+===============
-+
-+If you are experiencing problems that you think are DT-related, enable DT
-+diagnostic output by adding this to /boot/config.txt:
-+
-+ dtdebug=on
-+
-+and rebooting. Then run:
-+
-+ sudo vcdbg log msg
-+
-+and look for relevant messages.
