    That's the SoC (OMAP) side.

    That's not needed (but does not hurt). The Droid 4
    has no TWL companion chip and uses CPCAP instead.

    That's the codec side.

    You probably did not enable the soundcard driver, that binds against
    "audio-graph-card" compatible and connects the codec driver with the
    SoC driver: CONFIG_SND_AUDIO_GRAPH_CARD
