[PATCH v5 0/6] Add support for S4 audio

[jiebing chen via B4 Relay]

This series completes the end-to-end audio support
for S4 SoC from hardware bindings to driver implementation
and system integration.

1 Device Tree Bindings Updates 
Added audio power domain support for S4 SoC.Defined mclk/sclk pad clock IDs in AXG audio bindings.
Add S4 audio tocodec binding support.

2 Driver Implementation
Implemented S4 tocodec driver for G12A architecture.
Add mclk pad divider support for S4 in AXG audio clock.

3 Device Tree Integration
Add Amlogic S4 audio subsystem support in arm64 DTS.
