+Subject: OMAP: Make video mode selectable from pre-defined list
+X-Git-Url: http://git.mansr.com/?p=linux-omap;a=commitdiff_plain;h=7a9e55d7156dae6bc930c77620a88a669d2ed1c9
+
+OMAP: Make video mode selectable from pre-defined list
+
+This adds a list of common video modes and allows one to be
+selected with video=omapfb:mode:name on the command line,
+overriding the defaults from lcd_*.c. A default named mode
+can also be specified in the kernel configuration.
