This node does not represent direct hardware resources but is necessary for driver initialization and platform device binding. Properties added in the device tree node: - samsung,num-pcm-playback (uint32): Maximum number of supported PCM playback devices. Here, PCM playback devices refer to ALSA PCM devices. - samsung,num-pcm-capture (uint32): Maximum number of supported PCM capture devices. Here, PCM capture devices refer to ALSA PCM devices. - samsung,num-i2s-dummy-backend (uint32): Maximum number of supported I2S dummy backend devices. The node is declared disabled by default in the main device tree source, and enabled via board-specific DTS overlays by setting status = "okay". This device tree binding document will be added under Documentation/devicetree/bindings/sound/samsung,exynosauto.yaml to describe the node properties and usage.
