OMAP: DSS2: Display Subsystem Driver core
The core files of DSS2. DSS2 commits are split a bit artificially to make the individual commits smaller, and DSS2 doesn't compile properly without the rest of the core commits. This shouldn't be a problem, as no configuration uses DSS2 yet. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>

+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.
+
+config OMAP2_DSS_DEBUG_SUPPORT
+ bool "Debug support"
+ default y
+ help
+ This enables debug messages. You need to enable printing
+ with 'debug' module parameter.

+ depends on OMAP2_DSS_DSI
+ help
+ Use DSI PLL to generate pixel clock. Currently only for DPI output.
+ DSI PLL can be used to generate higher and more precise pixel clocks.
+
+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.
+
+config OMAP2_DSS_MIN_FCK_PER_PCK
+ int "Minimum FCK/PCK ratio (for scaling)"
+ range 0 32
+ 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.
