grep '"mediatek,mt8192-msdc"' * -RnH
arch/arm64/boot/dts/mediatek/mt8192.dtsi:868:                   compatible = "mediatek,mt8192-msdc";
Documentation/devicetree/bindings/arm/mediatek/mediatek,mt8192-clock.yaml:112:        compatible = "mediatek,mt8192-msdc";
drivers/clk/mediatek/clk-mt8192-msdc.c:67:              .compatible = "mediatek,mt8192-msdc",

I am wondering that in this case, should we have also modify the bindings document
(mediatek,mt8192-clock.yaml)?


thanks,
Miles
