[PATCH v1 0/7] ASoC: dt-bindings: Add/Update #sound-dai-cells to Tegra related codecs

[PATCH v1 0/7] ASoC: dt-bindings: Add/Update #sound-dai-cells to Tegra related codecs

[Svyatoslav Ryhel]

Add/Update #sound-dai-cells to some codecs often used by Tegra devices.
Document #sound-dai-cells property for i2s and ac97 nodes of Tegra20
and Tegra30 devices since they all provide a single dai cell. Add these
properties to SoC level Tegra audio-related nodes. This is required for
creating more complex audio paths.

I must have set code correctly, but forgot to adjust the commit
message. I will update commit message in v2. I have to adjust wm8994
codec anyway.

[Severity: Medium]
Does replacing const: 0 with const: 1 break dtbs_check validation and
backwards compatibility for existing in-tree device trees?

All existing in-tree device trees using wlf,wm1811 or wlf,wm8994 specify
#sound-dai-cells = <0> and reference the codec with a 0-cell sound-dai
phandle:

arch/arm/boot/dts/samsung/exynos4212-tab3.dtsi:
    wm1811: audio-codec@1a {
        ...
        gpio-controller;
        #gpio-cells = <2>;
        #sound-dai-cells = <0>;

arch/arm/boot/dts/samsung/exynos4412-midas.dtsi:
    wm1811: audio-codec@1a {
        ...
        gpio-controller;
        #gpio-cells = <2>;
        #sound-dai-cells = <0>;

arch/arm/boot/dts/samsung/s5pv210-aries.dtsi:
    wm8994: audio-codec@1a {
        compatible = "wlf,wm8994";
        reg = <0x1a>;

        #sound-dai-cells = <0>;

The corresponding sound card bindings
(Documentation/devicetree/bindings/sound/samsung,midas-audio.yaml and
Documentation/devicetree/bindings/sound/samsung,aries-wm8994.yaml) and
machine drivers (sound/soc/samsung/midas_wm1811.c and
sound/soc/samsung/aries_wm8994.c) parse a bare codec phandle via
of_parse_phandle(codec, "sound-dai", 0) and hardcode the three codec DAIs.
Meanwhile, sound/soc/codecs/wm8994.c registers three DAIs without a custom
.of_xlate_dai_name callback, so snd_soc_get_dlc() in sound/soc/soc-core.c
supports both 0 cells and 1 cell.

Should #sound-dai-cells in
Documentation/devicetree/bindings/sound/wlf,wm8994.yaml use enum: [0, 1]
instead so that both existing 0-cell device trees and 1-cell consumers remain
valid?

We have existing Exynos users which are validated with 0, this will break
validation for them.

Yes, sorry, it should be enum [0, 1] my bad, I will update in v2.
