First way thank for this work
But I can't use it, I'm explain myself.

My LVDS connexion works fine because I display correctly the console under 
uboot (I work with CONFIG_VIDEO_LCD_MODE)

I use the wiki : http://linux-sunxi.org/LCD to convert my fex config to 
CONFIG_VIDEO_LCD_MODE for the uboot all work fine

But for the kernel nothing, I have some crazy line or black screen.

   - I add my lcd configuration into simple_panel.c (
   http://linux-sunxi.org/LCD)
   - I can seen the debug ligne came from LVDS driver.
   - My LCD screen is a dlc070ddg 7' 800x480 LVDS 18bits.
   - I work with a Olimex_A20-OLinuXino-Micro 
   <http://linux-sunxi.org/Olimex_A20-OLinuXino-Micro>.

I don't know where I can search If some body have a idea?

Thanks
