LCDIF driver for i.MX23 and i.MX28.
The LCDIF support four modes of operation
This driver depends on a correct setup of the pins used for this purpose (platform specific).
For the developer: Don't forget to set the data bus width to the display in the imx_fb_videomode structure. You will else end up with ugly colours. If you fight against jitter you can vary the clock delay. This is a feature of the i.MX28 and you can vary it between 2 ns ... 8 ns in 2 ns steps. Give the required value in the imx_fb_videomode structure.
