Subject[PATCH 5/8] ASoC: uniphier: add support for UniPhier AIO driver
Date
This patch adds for UniPhier AIO audio sound system.
This provides commonly used APIs for input/output
control registers and DMA interfaces 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.
