Hi
I've decided that I want to learn kernel hacking a little and because of
that and because of new HDMI CEC Framework in kernel 4.8 I chose to write
CEC driver for old Allwinner A10.
There in no CEC hardware core for this CPU and I think the only way is to
create implementation that uses bit bang

This thread does seem to suggest there is (some) CEC hardware...
Also some code here ;

Not sure if you missed it or i'm blind, just ignore if nonsense ;)

Hi,
Thank you guys for your great inputs.
Discussion was very very helpful and clarified lot of things.
Here is more of less my current master plan :)
1) finish first version of sunxi CEC adapter that is using
pooling of HDMI CEC register. This version will be without
EDID parsing. Even if we lat
