Hi Laurent,

I just tried today's mainline kernel which has:

950e2fb [media] omap_vout: use omapdss's version instead of cpu_is_*

but I still see the log message "omapdss OVERLAY error: check_overlay:
paddr cannot be 0" (full log: http://fpaste.org/jOBo/)

This doesn't affect the video display though since the framebuffer
video is working correctly.

Setting CONFIG_FB_OMAP2_NUM_FBS=1 in my .config makes the error
message disappear since the paddr is correctly
set for the first overlay:

[    3.175842] OMAPFB: allocated VRAM paddr 9e900000, vaddr de900000
[    3.182891] OMAPFB: paddr 9e900000

Best regards,
Javier
