ASoC: uniphier: add digital output volume for UniPhier sound system
This patch adds controllers for digital volume of PCM output. Volume
effects simply linear, not dB scale as follows:
  Gained PCM = Original * 0x4000 / Volume

The value range of volume is from 0x0001 to 0xffff. 0x0000 works as
mute. Initial value is 0x4000 (+0dB).

ASoC: uniphier: add syscon property for UniPhier sound system
This patch adds syscon property for specifying soc-glue core.

Currently, soc-glue core is used for changing the state of S/PDIF
signal output pin to signal output state or Hi-Z state. After
resetting of SoC Hi-Z state is selected. This driver set to signal
output state when syscon property is available.

ASoC: uniphier: fix broken sound if use SRC in replay
This patch fixes settings for ports with SRC. These ports need to
set the fixed audio rate and clock. If not, the SRC outputs broken
sound.

ASoC: uniphier: add support for UniPhier AIO common driver
This patch adds common functions for UniPhier AIO audio sound
system. This provides commonly used APIs for input/output control
registers for UniPhier AIO.

This module provides all sound devices for I2S, S/PDIF and so on.
Since the AIO has mixed register map for those I/Os, it is hard
to split register areas for each sound devices.
