[PATCH v6 0/5] 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 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.

Looks fine otherwise except for the DTB warning, so something here 
doesn't match.

[PATCH v6 3/5] ASoC: meson: g12a-toacodec: Add S4 tocodec driver

[Jiebing Chen via B4 Relay]

From: Jiebing Chen <jiebing.chen@amlogic.com>

The S4 requires additional clock control bits to be turn on while enabled.
The S4 has 8 TDM lanes, instead of 4 on previous SoC.
Update the widget accordingly.

I guess that works but it is a bit hackish to hijack the output control
to enable a something really clock related. A supply widget connect to
this widget would be more approriate I think

Hi, jerome

Thanks for your suggestion. A supply widget is  appropriate.

I will add the supply widget in next version

[PATCH v6 4/5] clk: meson: axg_audio: add S4 support

[Jiebing Chen via B4 Relay]

From: Jiebing Chen <jiebing.chen@amlogic.com>

Add S4 support the axg audio clock controllers, Compared with the
previous version, the selection of the audio's clock and data pad
will be designed in the form of pinmux control. The purpose of doing
this is to distinguish between clock control and pin control selection.

Hi, jermoe

Considering that the sample rate is up to 176.4K

PLL0 270.950400M max support 24bit *176.4k, 32ch for tdm mode

Perhaps PLL1 PLL1 calculation error , it should be set up 361.2672M for 
32bit * 176.4k * 32ch.

In fact, most situations are limited by the speed of the IO pin.

Can we remove MPLL1 here and keep MPLL0?

That's not really the question here and there are interfaces (internal
for example) for which it can go higher than that.

... again, no everything goes through those pins.

That's up to you really. I'm merely pointing out that out of the 3 clock
sources, 2 are setup to serve derivative of 44.1kHz, which is useless.

Yes, if the number of tdm slots is smaller, theoretically it is possible 
to support a higher sample rate.

Two PLLs are indeed unnecessary. I will remove one in next version. thanks

Jiebing,

FYI

I applied this series over 6.18.7 and tested on s905w2 device.

With audio routing like this:

amixer cset numid=40,iface=MIXER,name='FRDDR_A SINK 1 SEL' 0
amixer cset numid=73,iface=MIXER,name='TDMOUT_A SRC SEL' 0
amixer cset numid=37,iface=MIXER,name='FRDDR_A SRC 1 EN Switch' 1
amixer cset numid=61,iface=MIXER,name='TOACODEC SRC' 0
amixer cset numid=1,iface=MIXER,name='TOACODEC Lane Select' 0
amixer cset numid=62,iface=MIXER,name='TOACODEC OUT EN Switch' 1
amixer cset numid=17,iface=MIXER,name='ACODEC Playback Volume' 251 251

i'm getting working audio on analog headset.

Great work!

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: a0c666c25aeefd16f4b088c6549a6fb6b65a8a1d (use --merge-base to override)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
