Subject: [PATCH v2 0/2] Enable audio output on AM62-SK

This patch series adds support for audio output via headphone jack on the
AM62-SK board. The jack is wired to TLV320AIC3106 (codec), which is
connected to McASP (serializer).

The same 3.5mm jack can be used for combined playback+recording, but audio
input is currently disabled on McASP until further testing and debugging.

For testing, please apply this series on top of
https://lore.kernel.org/all/[email protected]/ and
https://lore.kernel.org/alsa-devel/[email protected]/

Changelog:

V2:
- Move out the patch for sound/soc/ti/davinci-mcasp.c from this series
