menuconfig OMAP2_DSS tristate "OMAP2/3 Display Subsystem support (EXPERIMENTAL)" depends on ARCH_OMAP2 || ARCH_OMAP3 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=" 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 /omapdss/dispc_irq for DISPC interrupts, and /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 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. endif
