help
OMAP2/3 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_SUPPORT
bool "Debug support"
default y
help
This enables debug messages. You need to enable printing
with 'debug' module parameter.
config OMAP2_DSS_RFBI
bool "RFBI support"
default n
help
MIPI DBI, or RFBI (Remote Framebuffer Interface), support.
config OMAP2_DSS_VENC
bool "VENC support"
default y
help
OMAP Video Encoder support.
config OMAP2_DSS_SDI
bool "SDI support"
depends on ARCH_OMAP3
default n
help
SDI (Serial Display Interface) support.
config OMAP2_DSS_DSI
bool "DSI support"
depends on ARCH_OMAP3
default n
help
MIPI DSI support.
config OMAP2_DSS_USE_DSI_PLL
bool "Use DSI PLL for PCLK (EXPERIMENTAL)"
default n
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.
