Subject: [PATCH 0/7] ASoC: codec: Convert to GPIO descriptors

of_gpio.h is deprecated, update the driver to use GPIO descriptors.

Mostly about dropping legacy platform data usage, and switching
to use devm_gpiod_get_optional to get GPIO descriptors and use
gpiod_set_value to configure output.

Because of lacking of DTS users, I checked datasheet especially
for CS42Lxx and update code accordingly.

I not have devices to test, so just my best effort to do this work.
For cs42lxx codecs, there is no in-tree users for quite long time,
I was thinking to remove the drivers. But in case people have concern,
so I still do the convertion.
For those that have in-tree uers, I have added Cc in each patch and
appreciate if there is T-b from users.

With this patchset post out for ASoC, the left one under ASoC is
sound/arm/pxa2xx-ac97-lib.c which I have not looked into.

For others, below patches are alreay in maillist for reviewing.
ASoC: codec: sma1307: Remove including of_gpio.h
ASoC: codec: wcd9335: Convert to GPIO descriptors
ASoC: codec: wcd938x: Convert to GPIO descriptors
ASoC: codec: wcd939x: Convert to GPIO descriptors
ASoC: codec: ak5386: Convert to GPIO descriptors
