Almost every board machine / sound cards has "audio-routing" and "model" properties, so move them to common schema to have only one definition of these properties. For amlogic,gx-sound-card, drop the minItems: 2 from the "audio-routing", because any limit here - lower or upper- is rather meaningless. This will also fix `dtbs_check` warnings like: meson-gxm-s912-libretech-pc.dtb: sound: audio-routing: ['AU2 INL', 'ACODEC LOLN', 'AU2 INR', 'ACODEC LORN', '7J4-14 LEFT', 'AU2 OUTL', '7J4-11 RIGHT', 'AU2 OUTR'] is too long Reviewed-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Link: https://lore.kernel.org/r/20230810063300.20151-1-krzysztof.kozlowski@linaro.org Signed-off-by: Mark Brown <broonie@kernel.org>
