- 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_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.

- 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.
