Subject: [PATCH v9 0/6] arm64: ti: Enable audio on AM62 and AM62A

This patch series adds support for audio via headphone jack on SK-AM62
(E2+) and SK-AM62A boards. 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.

Changes in v9:
- Use correct codec 1.8V supply (PMIC) for SK-AM62-LP
- Link to v8: https://lore.kernel.org/r/20230313-mcasp_upstream-v8-0-4408134eb2f3@ti.com

The range-diff between v9 and v8 is given below:
