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.

This patch adds supports for UniPhier AIO DMA.

This module shared register area with 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.
