Commit Message

Add devicetree binding schema for the ADAMV block implemented on Socionext
Uniphier SoCs.

The ADAMV block is analog signal amplifier that is a part of the external
video and audio I/O system. This block is implemented on LD11 and LD20,
and this is defined for controlling audio I/O reset only.
