      ARM: pxa: poodle: use platform data for poodle asoc driver · ac70f4d8
      Arnd Bergmann authored 
      The poodle audio driver shows its age by using a custom
gpio api for the "locomo" support chip.

In a perfect world, this would get converted to use gpiolib
and a gpio lookup table.

As the world is not perfect, just pass all the required data
in a custom platform_data structure. to avoid the globally
visible mach/poodle.h header.

      ARM/pxa/mfd/power/sound: Switch Tosa to GPIO descriptors · 813c2aee
      Linus Walleij authored 
      The Tosa device (Sharp SL-6000) has a mishmash driver set-up
for the Toshiba TC6393xb MFD that includes a battery charger
and touchscreen and has some kind of relationship to the SoC
sound driver for the AC97 codec. Other devices define a chip
like this but seem only half-implemented, not really handling
battery charging etc.

This patch switches the Toshiba MFD device to provide GPIO
descriptors to the battery charger and SoC codec. As a result
some descriptors need to be moved out of the Tosa boardfile
and new one added: all SoC GPIO resources to these drivers
now comes from the main boardfile, while the MFD provide
GPIOs for its portions.

As a result we can request one GPIO from our own GPIO chip
and drop two hairy callbacks into the board file.

This platform badly needs to have its drivers split up and
converted to device tree probing to handle this quite complex
relationship in an orderly manner. I just do my best in solving
the GPIO descriptor part of the puzzle. Please don't ask me
to fix everything that is wrong with these driver to todays
standards, I am just trying to fix one aspect. I do try to
use modern devres resource management and handle deferred
probe using new functions where appropriate.
