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?

EDID is correctly read (I verified that it is the same as with the v5
version of the driver), but there's one difference I noted. v5 says dpms
is Off, while v6 says dpms is On.

Which resolution do you expect?
