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

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.

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

<debugfs>/omapdss/dsi_irq for DSI interrupts.

SDI (Serial Display Interface) support.
SDI is a high speed one-way display serial bus between the host

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.
See http://www.mipi.org/ for DSI specifications.
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.
