+ -----------
+ 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.
