Subject: [PATCH 6/6] arm64: dts: allwinner: bananapi-m64: Enable S070WV20-CT16 DSI panel
Date: Fri, 15 Mar 2019 18:38:25 +0530 [thread overview]
Message-ID: <20190315130825.9005-7-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190315130825.9005-1-jagan@amarulasolutions.com>
This patch add support for Bananapi S070WV20-CT16 DSI panel to
BPI-M64 board.
Bananapi S070WV20-CT16 is a pure RGB output panel with ICN6211 DSI/RGB
convertor bridge, so enable bridge along with associated panel.
DSI panel connected via board DSI port with,
- DLDO1 as VCC-DSI supply
- PD6 gpio for reset pin
- PD5 gpio for backlight enable pin
- PD7 gpio for backlight vdd supply
