Progress update:
Yesterday I managed to update PVR kernel drivers to "something" that compiles with current kernel by removing the following:
/proc entries as the code is not updated to use seq_file required in kernel >= 3.10
notification between OMAP DSS display driver and PVR (this is not implemented in OMAP DSS)
power management features (they are not implemented in kernel:
https://github.com/torvalds/linux/bl...omap-pm-noop.c
)
However, to even try getting the display to work we still need the following:
implement support for
pyrenees
(N9) and
himalaya
(N950) OMAP DSS displays
add DT OMAP DSS parts necessary to
omap-n9.dts
and
omap-n950.dts
In 3.5.3 that stuff was in the following files (list may not be complete):
https://github.com/filippz/kernel-ad...el-nokia-dsi.c
(
taal
,
himalaya
and
pyrenees
)
https://github.com/filippz/kernel-ad...lays/ctrl-gf.c
(mentions
himalaya
specific hacks)
https://github.com/filippz/kernel-ad.../board-rm680.c
Good news
: display driver might be ready in
https://github.com/torvalds/linux/bl...panel-dsi-cm.c
(
taal
is mentioned there, probably needs tweaking for
himalaya
and
pyrenees
). Seems that there were plans for adding other display types into it, but were abandoned:

Bad news
: I really don't know enough about this to be able to port these parts myself
Any volunteers
