SubjectRe: [PATCH v13 02/11] dt-bindings: soc: Add MT8183 power dt-bindings
Hi Weiyi Lu,

Thank you for the patch. Just a trivial comment below.

> Add power dt-bindings of MT8183 and introduces "BASIC" and
> "SUBSYS" clock types in binding document.
> The "BASIC" type is compatible to the original power control with
> clock name [a-z]+[0-9]*, e.g. mm, vpu1.
> The "SUBSYS" type is used for bus protection control with clock
> name [a-z]+-[0-9]+, e.g. isp-0, cam-1.
