ASoC: qcom: common: Respect status = "disabled" on DAI link nodes
At the moment, the DAI link nodes in the device tree always have to be specified completely in each device tree. However, the available interfaces (e.g. Primary/Secondary/Tertiary/Quaternary MI2S) are common for all devices of a SoC, so the majority of the definitions can be placed in a common device tree include to reduce boilerplate. Make it possible to define such stubs in device tree includes by respecting the "status" property for the DAI link nodes. This is a trivial change that just requires switching to the _available_ OF functions that check the "status" property additionally. This allows defining a stub like: sound_dai_quaternary: dai-link-quaternary { link-name = "Quaternary MI2S"; status = "disabled"; /* Needs extra codec configuration */ cpu { sound-dai = <&q6afedai QUATERNARY_MI2S_RX>; }; platform { sound-dai = <&q6routing>; }; }; where the codec would be filled in by the device-specific device tree. For existing device trees this change does not make any difference. A missing "status" property is treated like status = "okay".
