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.
The series depends on PMIC support:

Some of the patches have been posted (and reviewed) before as part of a
combined audio series (v9) for AM62 & AM62A:
https://lore.kernel.org/all/[email protected]/
Changes since v9 of last series:
- Use DVDD (1.8V) supply from TPS6594 PMIC
- Drop OCMV configuration as DVDD is present now
- Lower i2c-1 rate to 100Khz after testing on multiple boards
- Enable PMIC drivers (as modules) in defconfig

The TLV320AIC3106 audio codec is interfaced on the i2c-1 bus. With the
default rate of 400Khz the i2c register writes fail to sync:
[ 36.026387] tlv320aic3x 1-001b: Unable to sync registers 0x16-0x16. -110
[ 38.101130] omap_i2c 20010000.i2c: controller timed out
Dropping the rate to 100Khz fixes the issue.

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