Hi,

add a dt-bindings prefix and move the patch to the first order in the series.

mt6358regulator is not a required property, it is just a node alias.

it is not necessary to document the PMIC part in the regulator binding

and you can refer to mt6380-regulator.txt or mt6323-regulator.txt
first to make the
style about the PMIC description and example be more consistent.

use a generic node, regulators, something like

regulators {
compatible = "mediatek,mt6358-regulator";

add a blank line between subnodes which includes all below occurrences
