Hi Johannes,
thanks for your patch.

I'm not sure if we should call it rev-b since this is quite confusing.
The whole EVK bundle (cpu-board + baseboard) is called EVKB. The most
recent cpu board revision is A4 and the the cpu board itself is called
8MMINILPD4-CPU2 whereas the older cpu board is called 8MMINILPD4-CPU.
So dts file name imx8mm-evkb is correct, but mention it as rev-b in your
commit message is wrong in my opinion.

Do we really need to move it into another dtsi file? I would either
suggest to move the pmic description into the .dts file since it is not
common anymore. This way we can avoid the imx8mm-evk-rohm-pmic.dtsi.

Marco
