Subject: [PATCH v4 25/26] [DO NOT MERGE] arm64: dts: allwinner: bananapi-m64: Bananapi S070WV20-CT16 DSI panel
Date: Tue, 13 Nov 2018 16:46:32 +0530	[thread overview]
Message-ID: <20181113111633.20189-26-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20181113111633.20189-1-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,
- DC1SW as AVDD supply
- DCDC1 as DVDD supply
- PD6 gpio for reset pin
- PD5 gpio for backlight enable pin
- PD7 gpio for backlight vdd supply
