Hi Joakim,

I noticed that some of the compat strings being added are used in imx
dtsi files today:

john@localhost:~/linux> git grep "fsl,imx8mm-ddr-pmu"
arch/arm64/boot/dts/freescale/imx8mm.dtsi: compatible =
"fsl,imx8mm-ddr-pmu", "fsl,imx8m-ddr-pmu";

Any specific reason why they are not described in the dt bindings already?

I don't follow dt so much anymore, so don't know the policies.

> + "fsl,imx8mn-ddr-pmu"

Thanks,
John
