if you have an oscilloscope, can you probe PIXCLK, HSYNC, VSYNC and DE
to check the signals are properly configured vs the datasheet of your
display.

Yes, I have measured VSYNC and there is no activity on this line.

Also tried 3.13 with a non-dt kernel and the same issue is seen.

Running FSL 2.6.31 I can see VSYNC at 57Hz and Tux on the display, so
the hardware is good.

At least for me imxfb seems to be broken even for the non-dt case.

I will check the latest changes on the weekends for i.MX27.

I acknowledge that the (linux-next-20140314) framebuffer driver works fine.
Today I checked it on Phytec-PCM970 board with i.MX27 (DT).

Nevertheless, I ask Tomi to apply at least two patches for this driver:
