+ Normally the LCD is page-aligned (tyically 4KB). If this is

+There are different ways of describing a display mode. The devicetree

+
+Required subnode 'rgb' is as follows:

+Required properties (rgb) :

+
+The panel node describes the panel itself. This has the properties listed in
+displaymode.txt as well as:
+
+Required properties (panel) :
+ - nvidia,bits-per-pixel: number of bits per pixel (depth)
+ - nvidia,pwm : pwm to use to set display contrast (see tegra20-pwm.txt)
+ - nvidia,panel-timings: 4 cells containing required timings in ms:
+ * delay before asserting panel_vdd
+ * delay between panel_vdd-rise and data-rise
+ * delay between data-rise and backlight_vdd-rise
+ * delay between backlight_vdd and pwm-rise
+ * delay between pwm-rise and backlight_en-rise
+
+Optional GPIO properies all have (phandle, GPIO number, flags):
