This patch series, adds support for analog audio on J721S2 EVM using
device tree overlays.
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.

However, the system controller on J721S2 also contains audio reference clock controllers (ti,am62-audio-refclk) that use the same clock-controller@XXXX naming pattern. Hence, extend the clock-controller pattern to accept either ehrpwm-tbclk or audio-refclk schemas using a oneOf constraint.

The compatible string identifies the IP block, not the SoC family. This is already an established pattern — k3-j784s4-j742s2-main-common.dtsi uses the same compatible for the J784S4/J742S2 audio refclk node. The ti,j721e-system-controller.yaml binding (which covers ti,j721s2-system-controller) already lists ti,am62-audio-refclk as an allowed clock-controller child, which was updated in patch 1/2 of this series to make room for this node.
