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.
v4:
Use audio-friendly 96Mhz source as clock parent for mcasp
v3:
Fix regulator, clock and codec node names
v2:
Move out the patch for sound/soc/ti/davinici-mcasp.c into a separate series
v3: https://lore.kernel.org/all/[email protected]/
v2: https://lore.kernel.org/all/[email protected]/
v1: https://lore.kernel.org/all/[email protected]/

2.17.1
Add nodes for audio codec and sound card, enable the audio serializer
(McASP1) under use and update pinmux. Disable all other McASP nodes.
Audio input is currently not working properly, so the RX port on McASP1
is disabled for now, until the issue is debugged.
The serializer is shared between HDMI and codec. By default codec is
used for output, but it can be toggled to HDMI using a FET switch
connected to the MCASP1_FET_SEL (J24) header on the board.

2.17.1
From: Jayesh Choudhary <[email protected]>
Add the nodes for McASP 0-2.
Use the audio-friendly 96MHz main_1_hsdivout6_clk as clock parent
instead of the default 100Mhz main_2_hsdivout8_clk source.

I cant pick up a patch with compatibles that are'nt converted to yaml.
Please convert to yaml in master and then post.

we don't need to set okay on a node that is ok by default.
