Subject: [PATCH v6 0/5] Add support for S4 audio

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 and S4 audio clock support for S4 SoC.
Added S4 audio tocodec binding support.

2 Driver Implementation
Implemented S4 tocodec driver for G12A architecture.
Added S4 audio clock support in AXG audio clock 

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