[PATCH] arm64: dts: mediatek: mt8173: Add gce-client-reg handle to disp-mutex

Posted by AngeloGioacchino Del Regno 3 years, 11 months ago

Add a gce client reg handle to the disp mutex to enable MT8173
platforms to use MediaTek's CMDQ for extra performance.

As a note, this was successfully tested on MT8173 Acer Chromebook R13 (Elm).

Cheers,
