menuconfig OMAP2_DSS
tristate "OMAP2+ Display Subsystem support (EXPERIMENTAL)"
depends on ARCH_OMAP2PLUS
help
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_SUPPORT
bool "Debug support"
default y
help
This enables debug messages. You need to enable printing
with 'debug' module parameter.
config OMAP2_DSS_COLLECT_IRQ_STATS
bool "Collect DSS IRQ statistics"
depends on OMAP2_DSS_DEBUG_SUPPORT
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"
default y
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 spesifications.
config OMAP2_DSS_VENC
bool "VENC support"
default y
help
OMAP Video Encoder support for S-Video and composite TV-out.
config OMAP4_DSS_HDMI
bool "HDMI support"
depends on ARCH_OMAP4
default y
help
HDMI Interface. This adds the High Definition Multimedia Interface.
See http://www.hdmi.org/ for HDMI specification.
config OMAP2_DSS_SDI
bool "SDI support"
depends on ARCH_OMAP3
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"
depends on ARCH_OMAP3
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.
See http://www.mipi.org/ for DSI spesifications.
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.
