>
> Patch 1 splits out RK3288 HDMI code in a way that it is appropriate
> for sharing with Allwinner SoCs.
>
> Patch 2 splits out TCON code which is completely reusable on
> all Allwinner SoCs.
>
> Patch 3 (new) converts commont TCON code to use DM video compatible
> timing structure.
>
> Patch 4 adds all necessary clocks which are needed for Display
> Engine 2, TCON and HDMI.
>
> Patch 5 implement actual DE2 and HDMI driver and patch 6 disables HDMI
> on all boards which don't have it (default is on).
>
> Patch 7 is included here only for testing HDMI output on A64 due
> to missing power regulator support (AXP803). Another option is to
> use ATF which powers on HDMI. Such ATF can be found on Andre

> Code was tested on OrangePi 2 & OrangePi Plus 2E (both H3),
> OrangePi PC 2 (H5) and Pine64 (A64). It was also tested on RK3288 Tinker

I tested the patched U-Boot on A10 with HDMI and A13 with LCD, and
it works properly.
