   DESCRIPTION
   -----------

   Only one panel may be defined at a time.

   The pixel clock is calculated to be no greater than the target.

   Each timing value is accompanied by a specification comment.

     UNITS/MIN/TYP/MAX

   Most of the units will be in clocks.

   USE_RGB555

     Define this macro to configure the AMBA LCD controller to use an
     RGB555 encoding for the pels instead of the normal RGB565.

   LPD9520, LPD79524, LPD7A400, LPD7A404-10, LPD7A404-11

     These boards are best approximated by 555 for all panels.  Some
     can use an extra low-order bit of blue in bit 16 of the color
     value, but we don't have a way to communicate this non-linear
     mapping to the kernel.
