* Port ANX78xx Pinebook / Teres LCD panel driver from 5.6-rc1 * Move Teres U-boot to 2020.01 ... it boots with enabled screen now. * U-boot 2020 needs some extra Pyton utils when packing sunxi bootloader. Adding to native and Docker build dependencies. * Add Pinebook lid wakeup * python3-dev is also needed dependency

Teres-I has an anx6345 bridge connected to the RGB666 LCD output, and
|
|
the I2C controlling signals are connected to I2C0 bus.
|
|
|
|
Enable it in the device tree, and enable the display engine, video mixer
|
|
and tcon0 as well.
