Jeez what a bit of a mess here - looks like I will have to punt this
series.
a) main_conf in arch/arm64/boot/dts/ti/k3-am62-main.dtsi is still
syscon, simple-mfd -> I had thought we have converted these already, but
apparently not.
b) we then have the yaml itself. Documentation/devicetree/bindings/mfd/ti,j721e-system-controller.yaml
it picks up clock-controller as ti,am654-ehrpwm-tbclk.yaml
but the actual binding is Documentation/devicetree/bindings/clock/ti,am62-audio-refclk.yaml
which is not enforced.
Jai: please sort this out before I can look at any of these audio
enablement patches involving refclk.
ALSO: please DONOT ignore dtbs_check warnings folks. it does show some
real issues in either bindings or dts.
