The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure.

+config OMAP2_VRAM_SIZE
+ int "VRAM size (MB)"
+ range 0 32
+ default 0
+ help
+ The amount of SDRAM to reserve at boot time for video RAM use.
+ This VRAM will be used by omapfb and other drivers that need
+ large continuous RAM area for video use.
+
+ You can also set this with "vram=<bytes>" kernel argument, or
+ in the board file.

+ Collect DSS IRQ statistics, printable via debugfs.
+
+ The statistics can be found from

+config OMAP2_DSS_DSI
+ bool "DSI support"
+ depends on ARCH_OMAP3 || ARCH_OMAP4
+ default n
+ help
+ MIPI DSI (Display Serial Interface) support.

+
+config OMAP2_DSS_FAKE_VSYNC
+ bool "Fake VSYNC irq from manual update displays"
+ default n
+ help
+ If this is selected, DSI will generate a fake DISPC VSYNC interrupt
+ when DSI has sent a frame. This is only needed with DSI or RFBI
+ displays using manual mode, and you want VSYNC to, for example,
+ time animation.

+ default 0
+ help
+ This can be used to adjust the minimum FCK/PCK ratio.
+
+ With this you can make sure that DISPC FCK is at least
+ n x PCK. Video plane scaling requires higher FCK than
+ normally.
+
+ If this is set to 0, there's no extra constraint on the
+ DISPC FCK. However, the FCK will at minimum be
+ 2xPCK (if active matrix) or 3xPCK (if passive matrix).
+
+ Max FCK is 173MHz, so this doesn't work if your PCK
+ is very high.
+
+config OMAP2_DSS_SLEEP_AFTER_VENC_RESET
+ bool "Sleep 20ms after VENC reset"
+ default y
+ help
+ There is a 20ms sleep after VENC reset which seemed to fix the
+ reset. The reason for the bug is unclear, and it's also unclear
+ on what platforms this happens.
+
+ This option enables the sleep, and is enabled by default. You can
+ disable the sleep if it doesn't cause problems on your platform.
