Subject[DO NOT MERGE] [PATCH v4 4/4] ARM: dts: sun8i: bananapi-m2m: Enable S070WV20-CT16 panel
Date
This patch add support for Bananapi S070WV20-CT16 panel to
BPI-M2M board.

Bananapi S070WV20-CT16 is a pure RGB output panel with ICN6211 DSI/RGB
converter bridge, so enable bridge along with associated panel.

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

Changes for v4:
- replace reset with enable-gpios
Changes for v3:
- none
