[PATCH 6/6] arm64: allwinner: a64: enable LCD-related hardware for Pinebook

From: Vasily Khoruzhick
Date: Thu Feb 20 2020 - 03:36:03 EST


From: Icenowy Zheng <icenowy@xxxxxxx>

Pinebook has an ANX6345 bridge connected to the RGB666 LCD output and
eDP panel input. The bridge is controlled via I2C that's connected to
R_I2C bus.

Enable all this hardware in device tree.
