Hello Marek,

Hi,

Could you share your get_maintainers.pl invocation? I'd like to
adjust the reviewer entry in MAINTAINERS, so such patches get
into our kernel@xxxxxxxxxxxxxx inbox as well.

Plain get_maintainer -f path/to/dts

Some more comments below.

+	pmic: pmic@25 {

Here you assume GPIO1_IO04 is muxed as GPIO.

+			MX8MP_IOMUXC_GPIO1_IO04__USDHC2_VSELECT		0xc1

Here you mux it for USDHC2_VSELECT though. Is this intended?

That's a good question, other DTs do the same thing, I suspect the sd-vsel-gpios could be dropped, but as long as it is not outright harmful, it can be used for backward compatibility to support less complete OSes which may not handle the eSDHC VSELECT bit , so I figured it is good to keep both options.
