2 tristate "OMAP2/3 Display Subsystem support (EXPERIMENTAL)"
3 depends on ARCH_OMAP2 || ARCH_OMAP3
5 OMAP2/3 Display Subsystem support.
14 The amount of SDRAM to reserve at boot time for video RAM use.
15 This VRAM will be used by omapfb and other drivers that need
16 large continuous RAM area for video use.
18 You can also set this with "vram=<bytes>" kernel argument, or
21 config OMAP2_DSS_DEBUG_SUPPORT
25 This enables debug messages. You need to enable printing
26 with 'debug' module parameter.
32 MIPI DBI, or RFBI (Remote Framebuffer Interface), support.
38 OMAP Video Encoder support.
45 SDI (Serial Display Interface) support.
54 config OMAP2_DSS_USE_DSI_PLL
55 bool "Use DSI PLL for PCLK (EXPERIMENTAL)"
57 depends on OMAP2_DSS_DSI
59 Use DSI PLL to generate pixel clock. Currently only for DPI output.
60 DSI PLL can be used to generate higher and more precise pixel clocks.
62 config OMAP2_DSS_FAKE_VSYNC
63 bool "Fake VSYNC irq from manual update displays"
66 If this is selected, DSI will generate a fake DISPC VSYNC interrupt
67 when DSI has sent a frame. This is only needed with DSI or RFBI
68 displays using manual mode, and you want VSYNC to, for example,
71 config OMAP2_DSS_MIN_FCK_PER_PCK
72 int "Minimum FCK/PCK ratio (for scaling)"
76 This can be used to adjust the minimum FCK/PCK ratio.
78 With this you can make sure that DISPC FCK is at least
79 n x PCK. Video plane scaling requires higher FCK than
82 If this is set to 0, there's no extra constraint on the
83 DISPC FCK. However, the FCK will at minimum be
84 2xPCK (if active matrix) or 3xPCK (if passive matrix).
86 Max FCK is 173MHz, so this doesn't work if your PCK
