Subject: Re: [PATCH v1 1/6] dt-bindings: display/mediatek: mt8188: Add
 documentations for VDOSYS1

Hi, Hsiao-chien:

Separate mmsys part to another patch because it would go through
different maintainer's tree.

Separate padding part to another patch because it's a new device.

Regards,
Chun-Kuang.
