These 3 patches add the support to enable audio on J721S2-EVM.

This required the i2c-mux support[0] which is now in linux tree.

Now, this series ***depends upon only one dts change[1]*** to ensure there
are no dtbs_check warnings (no functional issues):
"ti,j721e-system-controller.yaml" refers to "ti,am654-ehrpwm-tbclk.yaml"
for clock-controller nodes, but for audio we need "ti,am62-audio-refclk".
When scm_conf is "simple-bus", there are no such warnings.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/next-20250604 (best guess, 1/2 blobs matched)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!

[1/3] arm64: dts: ti: k3-j721s2-main: Add McASP nodes
      commit: 56bf596ff9026b616137968102884233c86055d4

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.
