so, I have tested this serie on pandaboard, using meta-ti layer for
the BSP and poky (i used master-next branch which has these patches).
I have tested with a couple of patches that I sent to meta-ti to
revert the xf86-video-omap that we had in meta-ti. For the reference,
i tested with this:
https://github.com/ndechesne/meta-ti/commits/test_new_xf-v-o (my new
patches aren't merged yet in master).

i tested with xf86-video-omap, not -omapfb, and with a v3.4 kernel
which I know has a working omapdrm driver.

it all looks good, the driver is loaded, and I tested resolution
change, as well as rotation , both with xrandr command (i tested
core-image-x11 image).

many thanks for sorting this out...

i have some questions... xf86-video-omap now clearly depends on opengl
DISTRO_FEATURE (since dri cannot be disabled) for the xserver build.
So if i build oe-core + meta-ti, it won't build as the xserver is
built without dri/glx support there, and then xf86-video-omap won't
build.
 - how should we handle that? it doesn't sound quite right to enfore a
DISTRO feature in a recipe... but is it possible to have a check for
opengl in the recipe? that would avoid a more cryptic build error..
 - how can I make an oe-core+meta-ti to build for Panda with this
video driver? e.g. where should I set this DISTRO_FEATURE in meta-ti,
outside of 'poky' distro, e.g. in a BSP layer?. I recall that we have
this in the xserver recipe:

PACKAGECONFIG ??= "udev ${@base_contains('DISTRO_FEATURES', 'opengl',
'glx', '', d)}"
PACKAGECONFIG[udev] = "--enable-config-udev,--disable-config-udev,udev"
PACKAGECONFIG[glx] = "--enable-dri --enable-dri2 --enable-glx --enable-glx-tls,\
                      --disable-dri --disable-dri2 --disable-glx,\
                      xf86driproto dri2proto mesa-dri"

thx
