- OMAP2+ Display Subsystem support.
- if OMAP2_DSS
- 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
- bool "Debug support"
- default n
- help
- This enables printing of debug messages. Alternatively, debug messages
- can also be enabled by setting CONFIG_DYNAMIC_DEBUG and then setting
- appropriate flags in <debugfs>/dynamic_debug/control.
- config OMAP2_DSS_DEBUGFS
- bool "Debugfs filesystem support"
- depends on DEBUG_FS
- default n
- help
- This enables debugfs for OMAPDSS at <debugfs>/omapdss. This enables
- querying about clock configuration and register configuration of dss,
- dispc, dsi, hdmi and rfbi.
- config OMAP2_DSS_COLLECT_IRQ_STATS
- bool "Collect DSS IRQ statistics"
- depends on OMAP2_DSS_DEBUGFS
- default n
- help
- Collect DSS IRQ statistics, printable via debugfs.
- The statistics can be found from
- <debugfs>/omapdss/dispc_irq for DISPC interrupts, and
- <debugfs>/omapdss/dsi_irq for DSI interrupts.
- config OMAP2_DSS_DPI
- bool "DPI support"

- help
- DPI Interface. This is the Parallel Display Interface.
- config OMAP2_DSS_RFBI
- bool "RFBI support"
- default n
- help
- MIPI DBI support (RFBI, Remote Framebuffer Interface, in Texas
- Instrument's terminology).
- DBI is a bus between the host processor and a peripheral,
- such as a display or a framebuffer chip.
- See http://www.mipi.org/ for DBI specifications.
- config OMAP2_DSS_VENC

- config OMAP2_DSS_SDI
- bool "SDI support"
- default n
- help
- SDI (Serial Display Interface) support.
- SDI is a high speed one-way display serial bus between the host
- processor and a display.
- config OMAP2_DSS_DSI
- bool "DSI support"
- default n
- help
- MIPI DSI (Display Serial Interface) support.
- DSI is a high speed half-duplex serial interface between the host
- processor and a peripheral, such as a display or a framebuffer chip.

- 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.
- 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.
