Subject[PATCH v2] arm64: dts: rk3399-pinephone-pro: Add internal display support
Date
From: Ondrej Jirman <megi@xff.cz>

The phone's display is using a Hannstar LCD panel. Support it by adding a
panel DT node and all needed nodes (backlight, MIPI DSI, regulators, etc).

Changes in v2:
- Drop touchscreen node because used the wrong compatible (Ondrej Jirman).
- Fix assigned-clock-parents in vopb node (Ondrej Jirman).
- Add vopl and vopl nodes.
