I've spent the last two weeks feeling like Status Quo, in search of the
4th chord, trying to get hdmi audio and video working at the same time
with the imx-drm staging componentised architecture, for the F20
mainline kernel build. I think we are there......
I'm out of time, have other things I must do today, so Charles
(dsdreamer), if there is any chance of you installing the
3.14.0-0.rc5.git2.2.2.cs from CS testing repo on your F20 image, and
doing some testing with this, great!
I've not actually had anything connected to the hdmi port, I'm forcing
it to be initialised with "video=HDMI-A-1:1024x768@60e" on the kernel
cmd line options, but it looks like video is being initialised, /dev/fb0
is being created, and a "dw-hdmi-audio" device is now available.
