[PATCH 0/2] Add ZTE ZTE zx-aud96p22 audio codec driver

[Shawn Guo]

From: Shawn Guo <shawn.guo at linaro.org>

This is a pick-up of Baoyou's zx-aud96p22 audio codec driver
submission [1], with quite some significant rework as below.

 - Instead of hard-coding the GPIO used to control external amplifier,
   use generic devm_gpiod_get_optional() call to retrieve the GPIO
   defined in device tree.
 - Rather than directly using I2C bus calls, use REGMAP_I2C interface
   which is more common for accessing codec register via I2C bus.
 - Use snd_kcontrol_new infrastructural for Volume and Mute control.
 - Use DAPM widget and route for various power bits control.
 - A lot of code cleanups
