There is a fair amount of warnings when running 'make dtbs_check' with amlogic,gx-sound-card.yaml.

Ex: arch/arm64/boot/dts/amlogic/meson-gxm-q200.dt.yaml: sound: dai-link-0:sound-dai:0:1: missing phandle tag in 0 arch/arm64/boot/dts/amlogic/meson-gxm-q200.dt.yaml: sound: dai-link-0:sound-dai:0:2: missing phandle tag in 0 arch/arm64/boot/dts/amlogic/meson-gxm-q200.dt.yaml: sound: dai-link-0:sound-dai:0: [66, 0, 0] is too long

The reason is that the sound-dai phandle provided has cells, and in such case the schema should use 'phandle-array' instead of 'phandle', even if the property expects a single phandle.

Fixes: fd00366b8e41 ("ASoC: meson: gx: add sound card dt-binding documentation") Signed-off-by: Jerome Brunet jbrunet@baylibre.com --- Hi Mark,

The statement above is based on this LKML discussion I found: https://lkml.org/lkml/2019/9/30/382

To be honest, I don't really get why the consumer should know whether the phandle will have cells or not. AFAIK, the consumer does not care about this ...
