Hi,
we are working at the moment with i.MX6DL. I tried to setup new
display support (RGB interface) in Bootloader U-Boot. There is a
structure available, where I can define all the display timings:
   .mode	= {
   	.name           = "wvga-rgb",
   	.refresh        = 57,
   	.xres           = 800,
   	.yres           = 480,
   	.pixclock       = 33260,
   	.left_margin    = 42,
   	.right_margin   = 86,
   	.upper_margin   = 10,
   	.lower_margin   = 33,
   	.hsync_len      = 128,
   	.vsync_len      = 2,
   	.sync           = 0,
   	.vmode          = FB_VMODE_NONINTERLACED
But there I miss the edge definition of the pixel clock and data
enable.
The sync field is used to describe these characteristics,
and some of the flags are listed in drivers/video/mxcfb.h (FB_SYNC*)
and others in drivers/video/videomodes.h (FB_SYNC_VERT_HIGH_ACT).
