A commit message like this always is a good indicator that this wants to
be multiple patches ;-) [Keywords: "While at it", "And", ...]

Separate patch with nice description perhaps? (remove undocumented inputs)

Separate patch please, "use correct pin for lcd-reset pinctrl" or so.

separate patch please talking about regrouping the two
separate pmic pin-groups.
