-Subject: [PATCH] brcmfmac: switch to new platform data
-
-Platform data is only available for sdio. With this patch a new
-platform data structure is being used which allows for platform
-data for any device and configurable per device. This patch only
-switches to the new structure and adds support for SDIO devices.

-- *
-- *
-- * Note: the brcmfmac can be loaded as module or be statically built-in into
-- * the kernel. If built-in then do note that it uses module_init (and
-- * module_exit) routines which equal device_initcall. So if you intend to
-- * create a module with the platform specific data for the brcmfmac and have
-- * it built-in to the kernel then use a higher initcall then device_initcall
-- * (see init.h). If this is not done then brcmfmac will load without problems
-- * but will not pickup the platform data.
-- *
-- * When the driver does not "detect" platform driver data then it will continue
-- * without reporting anything and just assume there is no data needed. Which is
-- * probably true for most platforms.
-- *
-- * Explanation of the platform_data fields:
-- *
-- * drive_strength: is the preferred drive_strength to be used for the SDIO
-- * pins. If 0 then a default value will be used. This is the target drive
-- * strength, the exact drive strength which will be used depends on the
-- * capabilities of the device.
-- *
-- * oob_irq_supported: does the board have support for OOB interrupts. SDIO
-- * in-band interrupts are relatively slow and for having less overhead on
-- * interrupt processing an out of band interrupt can be used. If the HW
-- * supports this then enable this by setting this field to true and configure
-- * the oob related fields.
-- *
-- * oob_irq_nr, oob_irq_flags: the OOB interrupt information. The values are
-- * used for registering the irq using request_irq function.
-- *
-- * broken_sg_support: flag for broken sg list support of SDIO host controller.
-- * Set this to true if the SDIO host controller has higher align requirement
-- * than 32 bytes for each scatterlist item.
-- *
-- * sd_head_align: alignment requirement for start of data buffer
-- *
-- * sd_sgentry_align: length alignment requirement for each sg entry
-- *
-- * power_on: This function is called by the brcmfmac when the module gets
-- * loaded. This can be particularly useful for low power devices. The platform
-- * spcific routine may for example decide to power up the complete device.
-- * If there is no use-case for this function then provide NULL.
-- *
-- * power_off: This function is called by the brcmfmac when the module gets
-- * unloaded. At this point the device can be powered down or otherwise be reset.
-- * So if an actual power_off is not supported but reset is then reset the device
-- * when this function gets called. This can be particularly useful for low power
-- * devices. If there is no use-case for this function (either power-down or
-- * reset) then provide NULL.
-- *
-- * reset: This function can get called if the device communication broke down.
-- * This functionality is particularly useful in case of SDIO type devices. It is
-- * possible to reset a dongle via sdio data interface, but it requires that
-- * this is fully functional. This function is chip/module specific and this
-- * function should return only after the complete reset has completed.

-+ * module_exit) routines which equal device_initcall. So if you intend to
-+ * create a module with the platform specific data for the brcmfmac and have
-+ * it built-in to the kernel then use a higher initcall then device_initcall
-+ * (see init.h). If this is not done then brcmfmac will load without problems
-+ * but will not pickup the platform data.
