Subject: [DO NOT MERGE] [PATCH v10 6/6] arm64: dts: allwinner: bananapi-m64: Enable Bananapi S070WV20-CT16 DSI panel
Date: Sat,  5 Oct 2019 19:49:13 +0530	[thread overview]
Message-ID: <20191005141913.22020-7-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20191005141913.22020-1-jagan@amarulasolutions.com>

This patch add support for Bananapi S070WV20-CT16 DSI panel to
BPI-M64 board.

DSI panel connected via board DSI port with,
- DLDO1 as VCC-DSI supply
- DCDC1 as VDD supply
- PD7 gpio for lcd enable pin
- PD6 gpio for lcd reset pin
- PD5 gpio for backlight enable pin
