[PATCH 0/2] dt-bindings: sound: ti,pcm3168a: json-schema conversion and fixes

[Geert Uytterhoeven]

	Hi all,

This patch series is an attempt to convert the existing DT binding
documentation for the Texas Instruments PCM3168A Audio Codec to
json-schema ("another one bites the dust" ;-).

It consists of two parts:
  1. The actual DT binding conversion,
  2. An RFC patch to fix the impedance mismatch between the bindings
     and the description in the Shimafuji Kingfisher board DTS.

I'm not super-familiar with the audio details, so I would be very
grateful to receive your comments.

Thanks!

[PATCH 1/2] dt-bindings: sound: ti,pcm3168a: Convert to json-schema

[Geert Uytterhoeven]

Convert the Texas Instruments PCM3168A Audio Codec Device Tree binding
documentation to json-schema.

Add missing properties.
Drop unneeded pinctrl properties from example.

This is a bit unexpected. Looking at DTSes:
1. I see in ulcb-kf.dtsi with cells==0, but two endpoints. The dai cells
seem unused? In such case shall dai-cells be skipped if we have endpoints?

2. in k3-j721e-common-proc-board.dts has cells=1, but user's phandle
does not have an argument, so practically it is ==0? The user -
sound/soc/ti/j721e-evm.c - just gets the node and does not use cells,
right? So even though dai-cells==1, it does not matter, because user
gets its own parsing?

3. The pcm3168a driver also does not have any xlate function, but it
registers to DAIs, so all uses should be with cells==1 to select proper
DAI...

Can you extend the example with dai cells or with endpoints (or both,
depending on my previous comment...)

I have no idea (DAI is magic to me), and hope the audio experts
can provide some input...

It is a bit of magic to me too. Yet I think the correct usage of this is
with dai-cells=1. I think we can skip the choice here between
sound-dai-cells and endpoints (to allow only one) and only fix the value
here to =1.

This would also require changing
arch/arm64/boot/dts/renesas/ulcb-kf.dtsi to dai-cells=1.

Krzysztof

Fix this by:
  1. Moving the "mclk-fs" property to the endpoint nodes, where it
     belongs according to .../sound/audio-graph-port.yaml,
  2. Dropping the bogus "clocks" properties.

I'm not tested, but in my quick check,
we can use "mclk-fs" under "ports", and we need "clocks" under "endpoint".
So the issue is not dtsi side, but yaml side.

I will check and fix it, but it will be next week or later.

Thank you for your help !!

I have investigated about this patch, and it needs extra patch
which I will post if -rc1 was released.

Of course I will keep your name. But is it OK for you ?

Thank you for your help !!
