    ASoC: simple-card-utils: support snd_soc_get_dai_id() · 73b17f1a

    ALSA SoC needs to know connected DAI ID for detecting.
    It is not a big problem if device/driver was only for sound,
    but getting DAI ID will be difficult if device includes both
    Video/Sound, like HDMI.
    To solve this issue, this patch adds new snd_soc_get_dai_id() and
    its related .of_xlate_dai_id callback on component driver.
    In below case, we can handle Sound port (= port@2) as ID = 0
    if .of_xlate_dai_id has its support.
    
    	hdmi {
    		port@0 { /* VIDEO */ };
    		port@1 { /* VIDEO */ };
    		port@2 { /* SOUND */ };
    	};
