i.MX51 LVDS color and 2.6.38 [solved]

Hi all,

I'm working on a custom i.MX51 babbage board.

When I migrated from kernel 2.6.35 to freescale git branch  imx_2.6.38_11.11.01 (and also imx_2.6.38_11.09.01 and imx_2.6.38) we noticed that the six low significative bit of blue color (from DISP1_D0 to DISP1_D5) was no more active.

The effect is that blu have a "gross" definition; red and green are ok: 8 bit color depth each oen.

If we rollback to 2-6-35 all return pk. 


We sow the same  behavior on an original Freescale i.MX51 Babbage. Does anyone notice this problem too ? Any idea to solve ?

We are using video default configuration, (we also try other but nothing changed: kernel 2.6.35 works, 2.6.38 doesn't)


    .interface_pix_fmt = IPU_PIX_FMT_RGB24,
    .mode_str = "1024x768M-16@60",
    .default_bpp = 16,


we tested both dvi and LVDS output.

Hope someone can help me, just to say if his or her babbage board wors ok with 2.6.38
