These are dtsi/dts files that have SAI missing mclk0:
arch/arm/boot/dts/imx6ul.dtsi
arch/arm/boot/dts/imx6sx.dtsi
arch/arm/boot/dts/ls1021a.dtsi
arch/arm/boot/dts/imx7s.dtsi
arch/arm/boot/dts/vfxxx.dtsi
arch/arm64/boot/dts/freescale/imx8mq.dtsi
arch/arm64/boot/dts/freescale/fsl-ls1028a.dtsi
arch/arm64/boot/dts/freescale/fsl-ls1012a.dtsi
arch/arm64/boot/dts/freescale/fsl-ls1012a.dtsi

Would it be possible for you to update the others also?

Thanks
