In case of using MIXer with Simple Audio Card, it needs below DT.
simple-audio-card,dai-link@1 { cpu@0 { ... }; cpu@1 { ... }; ... };
This case, it requires "reg = <xxx>" which needs #address-cells/#size-cells, but simple-audio-card.yaml is missing these. This patch adds it.
Without this patch, we will get below warning.
${LINUX}/arch/arm64/boot/dts/renesas/r8a77950-ulcb.dtb: sound: simple-audio-card,dai-link@0: '#address-cells', '#size-cells' do not match any of the regexes: '^codec(@[0-9a-f]+)?', '^cpu(@[0-9a-f]+)?', 'pinctrl-[0-9]+' From schema: ${LINUX}/Documentation/devicetree/bindings/sound/simple-card.yaml
