[v9,6/6] arm64: dts: ti: k3-am62a7-sk: Enable audio on AM62A
Commit Message
Add nodes for audio codec and sound card, enable the audio serializer
(McASP1) under use and update pinmux.
The codec (TLV320AIC3106) is also supplied with a DVDD 1.8V supply from
the PMIC (TPS6593x) on the SK. [1] As the PMIC driver and devicetree
node is missing, skip describing DVDD for now and manually set the OCMV
voltage.

Please drop the am62a7 series from this patch series. once you add PMIC
device tree property, then lets add the dvdd properly rather than
reworking this again.
