same nit as for 1/5: maybe just 'arm64: dts: qcom: Add pml7350 support/.dtsi'
or similar since this adds the initial .dtsi for the pmk8350?

nit: also mention that it adds the pmk8350 .dtsi in the first place.

Please provide a link to the binding if it has been sent.

Is the usage of this keys really universal across different boards?
At least for the volume down key for most PMICs the config is in the
board file, which seems to make more sense.

nit: I think this should be 'alphabetical' order, so 'pm8350_die_temp' should
be before 'pmk8350_die_temp'.

Is it guaranteed that a board with the pmk8350 will always have the
other 3 PMICs?

nit: nodes should be ordered by address, hence 'rtc@6100' should be before
'gpios@b000'.
