[PATCH v3 06/17] dt-bindings: display: mediatek: dpi: add power-domains property

From: amergnat
Date: Thu Apr 18 2024 - 10:19:55 EST


From: Fabien Parent <fparent@xxxxxxxxxxxx>

DPI is part of the display / multimedia block in MediaTek SoCs, and
always have a power-domain (at least in the upstream device-trees).
Add the power-domains property to the binding documentation.
