Message

Hello All,

These three patches enable audio on J784S4-EVM platform.
- First patch adds the McASP nodes.
- Second patch adds the audio_refclk1 node that is required
  to configure the CTRL_MMR register for the external clock
- Third patch enables the analog audio

For audio to work, the ti-dm firmware that should be picked
for uboot is now publically available and will be shortly
merged to the ti-linux-firmware branch:
<https://git.ti.com/cgit/processor-firmware/ti-linux-firmware/tree/ti-dm/j784s4/ipc_echo_testb_mcu1_0_release_strip.xer5f?h=ti-linux-firmware-next>

For testing, ~/.asoundrc file was created in root partition
which can be seen in the test logs:
<https://gist.github.com/Jayesh2000/3ca38cbac2f37842b1010af79dfe9b4c>

Changelog v1->v2:
- Rebase on tag next-20240624
- Add padding in mcasp reg property
- Add assigned-clock and assigned-clock-parents property for mcasp
  for more accurate description
- Change mcasp pinmux node name similar to other nodes
- Fix typo in k3_clk node and remove unnecessary comments for refclk1

v1 patch:

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
