What information does "based on Actions Semi Owl SoC" give us? :)
The board name should be unique enough - Owl is a family of SoCs,
"actions:" is in the subject and "s900-" is in the filename.

Suggest to add that as comments above the two nodes instead.

Fine with me - maybe add a comment and make sure it's aligned with the
schematics naming wrt PMIC.

Wouldn't it make more sense to move these and the below pinctrl-* to
s900.dtsi for sharing with other theoretical boards? I really dislike
the imx model where pin muxing is duplicated into each individual board.

Andreas
