Hi all,

I'm working on a zoom2 dev board (omap34x-II MDP), and I can't draw
anything on the LCD display.

I've built kernel 2.6.35 from
git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git
and then applied the following patchs :
[PATCH 1/2 V7] OMAP: ZOOM2/3&SDP3630: Add display board file for zoom
boards <http://marc.info/?l=linux-omap&m=127445506720934&w=2>
[PATCH 2/2 V7] OMAP: ZOOM2/3&SDP3630: Add display board file for zoom
boards <http://marc.info/?l=linux-omap&m=127445522921326&w=2>
[PATCH V6] OMAP: DSS: Add NEC NL8048HL11-01B display panel
<http://marc.info/?l=linux-omap&m=127445535621669&w=2>

At this time the kernel boots well, and my LCD backlight turns on but
I can't draw anything.
I've checked, the framebuffer device is present and configured with
size of 800x480.

Perhaps I've missed something?

Thank you in advance.
