Subject: [PATCH 0/5] arm64: ti: Enable audio on AM62A

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/20230313-mcasp_upstream-v9-0-6d937efe4ec4@ti.com/

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
