This patch series adds support for audio via headphone jack on
SK-AM62A-LP. The jack is wired to TLV320AIC3106 (codec), which is
connected to McASP1 (serializer) on the SoC.
The TRRS 3.5mm jack can be used for simultaneous playback and recording.

VCC_3V3_MAIN is the output of LM5141-Q1, and it serves as an input to
TPS22965DSGT which produces VCC_3V3_SYS. [1]
