I received one answer by mail, init of lcd screen is done by u-boot, I found useful informations by looking in u-boot/configs/ folder and with some grep and looking tablets defconfig files. At least it works on my "no-name" a20 tablet I will try later on lime2, I didn't received the lcd cable yet.
useful options for lcd(in my case): CONFIG_VIDEO_LCD_MODE="x:800,y:480,depth:18,pclk_khz:33000,le:45,ri:209,up:22,lo:22,hs:1,vs:1,sync:3,vmode:0" CONFIG_VIDEO_LCD_POWER="PH8" CONFIG_VIDEO_LCD_BL_EN="PH7" CONFIG_VIDEO_LCD_BL_PWM="PB2" Alexis. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
