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.

+        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.

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

+        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.
