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?

You could very well have two panels and switch from one to another by changing the pin muxing, so we have to use an enpoint for that. This is pretty much the same case that we have with the A10s where we need to have two output endpoints for the TV Encoder and HDMI, something we cannot support right now in our binding, since we assume that we have the two channels that only have one user, which turned out to be wrong. I guess an easy way would be to have an extra property defining which channel the endpoint is attached to. Thanks, Maxime
