This patchset series adds HDMI video support to the Allwinner
sun8i SoCs which include the display engine 2 (DE2).
The driver contains the code for the A83T and H3, but it could be
used/extended for other SoCs as the A64, H2 and H5.

Hi,

I'm trying to test your patches on Orange Pi PC, and I've run into a few
issues: (I'm using sunxi-ng with the same patches as last time, to make
it work with your driver)

1] I just get pink output on the monitor - there's some signal, but it's
pink (or more like magenta).

dmesg ouput indicates no error:

	[snip]

My H3 boards work correctly, except the Orange PI 2 when it cannot read
the EDID (but it is OK after reboot).

Did you check if the EDID was correctly read?
Which resolution do you expect?
