Subject[PATCH v2 1/1] dt-bindings: display: mediatek: dpi: add power-domains property
Date
DPI is part of the display / multimedia block in MediaTek SoCs
and is managed using power controller in some platforms. We add
the power-domains property to the binding documentation.

Fixes:9273cf7d3942("dt-bindings: display: mediatek: convert the dpi bindings to yaml")
