[PATCH 19/27] arm64: dts: mediatek: mt6795: Add support for display blocks and DPI/DSI
From: AngeloGioacchino Del Regno
Date: Wed Apr 12 2023 - 07:29:20 EST
Introduce all nodes for all of the display blocks in the MediaTek Helio
X10 MT6795 SoC, including the DSI PHY and DSI/DPI interfaces: those are
left disabled as usage is board specific.
