Subject: [PATCH v5 0/6] 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 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.

Changes in v5:
- Fix warning Documentation/devicetree/bindings/clock/amlogic,axg-audio-clkc.yam when make dt_binding_check
- The audio reg is mounted below the APB bus in dts file.
- Deal with pad clock in a distinct controller.
- Fix warning for sound/soc/meson/g12a-toacodec.c
- Link to v4: https://lore.kernel.org/r/20250319-audio_drvier-v4-0-686867fad719@amlogic.com
Changes in v4:
- fix dtb check warning
- add maxItems of power domain for dt-bindings
- fixed audio clock pads regmap base and reg offset
- use dapm widget to control tocodec bclk and mclk enable
- Link to v3: https://lore.kernel.org/r/20250228-audio_drvier-v3-0-dbfd30507e4c@amlogic.com
Changes in v3:

- Modify the incorrect title for dt-bindings
- Link to v2: https://lore.kernel.org/r/20250214-audio_drvier-v2-0-37881fa37c9e@amlogic.com
Changes in v2:
- remove tdm pad control and change tocodec base on g12a
- change hifipll rate to support 24bit
- add s4 audio clock
- Link to v1: https://lore.kernel.org/r/20250113-audio_drvier-v1-0-8c14770f38a0@amlogic.com
