Subject: [PATCH v11 7/7] ARM: dts: sun8i: bananapi-m2m: Enable Bananapi S070WV20-CT16 DSI panel
Date: Thu,  3 Oct 2019 12:15:27 +0530	[thread overview]
Message-ID: <20191003064527.15128-8-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20191003064527.15128-1-jagan@amarulasolutions.com>

This patch add support for Bananapi S070WV20-CT16 DSI panel to
BPI-M2M board.

DSI panel connected via board DSI port with,
- DCDC1 as VCC-DSI supply
- DLDO1 as VDD supply
- PL5 gpio for lcd reset gpio pin
- PB7 gpio for lcd enable gpio pin
- PL4 gpio for backlight enable pin
