[PATCH v7 0/2] Enable audio support for J721S2 EVM

[Moteen Shah <m-shah@ti.com>]

Earlier version of the patchset sent upstream[0] was rejected as
its dependency[1], which resolves the DTBS check errors introduced
by [0] also got rejected on the grounds of ABI breakage.

Another solution to fix the DTBS check errors introduced by [0] is
to modify the ti,j721e-system-controller.yaml binding to allow
audio-refclk as clock-controller child. This is done in the first
patch of this series.

Changes since v6:
- Fix commit message in patch 2/2: split the I2C3 and McASP routing
  bullet to correctly describe I2C3 routing via gpio-mux controller
  and McASP serializer routing via GPIO hogs as separate items
- Add Reviewed-by from Sen

Changes since v5:
Link to v5:
https://lore.kernel.org/all/20260520115603.2662930-1-m-shah@ti.com/
- Move audio_refclk1 clock node from the overlay (k3-j721s2-evm-audio.dtso)
  to the main DTSI (k3-j721s2-main.dtsi) so it is always available
  independent of the overlay being applied
- Drop the &scm_conf block from the overlay since it is now in main.dtsi

Changes since v4:
Link to v4:
https://lore.kernel.org/all/20260519142341.2531948-1-m-shah@ti.com/
- Explicitly disable main_mcan3 and main_mcan5 as they will silently
  break mcasp audio routing
