First the bad news: display support is not in the mainline kernel.

since linux-omap tree follows the mainline, it's not there either

Tomi removed the n8x0 panel driver some time ago (I don't know why),

even then it wasn't working as the platform data failed to set up some
It would've been a big effort to keep the panel driver compiling, as we
moved to a new display driver architecture. And, as it wasn't working
anyway, I deemed it simpler to just remove it.
I have no objections to add it back, but it needs to be split into two
separate drivers, blizzard encoder driver and the panel driver. The
RFBI
driver also probably needs some love. And, of course, DT support for
all
those.
In theory, RFBI is relatively simple. If I recall right, the panel is
also quite simple, although it still needs to be controlled via SPI.
Blizzard was a bit more complex one, but perhaps most of its features
can be just left out.
But getting all those three working fine without being able to make any
measurements between the components, well, one might needs some luck
there =).
I do have N800 and N810 (no serial mods), so I might be able to give
some help there at some point, if I'm able to boot the board with usb
gadget ethernet (which hasn't been working for me for omap3 for some
time).
Hi Tomi,
In the following commit it states that you ported the old blizzard
driver to
the new omapdss driver:

OMAPFB: remove old blizzard driver
N8x0's blizzard driver has been ported to new omapdss driver, so we
can
now remove the old blizzard driver.

Did that driver work on the N810 at that point? If I look at the kernel
tree
at that point in time would all the components be there? It would make
it
easier if I had a starting point as I don't have any documentation so
reading
the old source code is the only way I can figure out how things
work(ed).
Regards,
Leigh.
