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.
28 config OMAP2_DSS_COLLECT_IRQ_STATS
29 bool "Collect DSS IRQ statistics"
30 depends on OMAP2_DSS_DEBUG_SUPPORT
33 Collect DSS IRQ statistics, printable via debugfs.
35 The statistics can be found from
36 <debugfs>/omapdss/dispc_irq for DISPC interrupts, and
37 <debugfs>/omapdss/dsi_irq for DSI interrupts.
43 DPI Interface. This is the Parallel Display Interface.
49 MIPI DBI support (RFBI, Remote Framebuffer Interface, in Texas
50 Instrument's terminology).
52 DBI is a bus between the host processor and a peripheral,
53 such as a display or a framebuffer chip.
55 See http://www.mipi.org/ for DBI spesifications.
61 OMAP Video Encoder support for S-Video and composite TV-out.
68 SDI (Serial Display Interface) support.
70 SDI is a high speed one-way display serial bus between the host
71 processor and a display.
78 MIPI DSI (Display Serial Interface) support.
80 DSI is a high speed half-duplex serial interface between the host
81 processor and a peripheral, such as a display or a framebuffer chip.
83 See http://www.mipi.org/ for DSI spesifications.
85 config OMAP2_DSS_USE_DSI_PLL
86 bool "Use DSI PLL for PCLK (EXPERIMENTAL)"
88 depends on OMAP2_DSS_DSI
90 Use DSI PLL to generate pixel clock. Currently only for DPI output.
91 DSI PLL can be used to generate higher and more precise pixel clocks.
93 config OMAP2_DSS_FAKE_VSYNC
94 bool "Fake VSYNC irq from manual update displays"
97 If this is selected, DSI will generate a fake DISPC VSYNC interrupt
98 when DSI has sent a frame. This is only needed with DSI or RFBI
99 displays using manual mode, and you want VSYNC to, for example,
102 config OMAP2_DSS_MIN_FCK_PER_PCK
103 int "Minimum FCK/PCK ratio (for scaling)"
107 This can be used to adjust the minimum FCK/PCK ratio.
109 With this you can make sure that DISPC FCK is at least
110 n x PCK. Video plane scaling requires higher FCK than
113 If this is set to 0, there's no extra constraint on the
114 DISPC FCK. However, the FCK will at minimum be
115 2xPCK (if active matrix) or 3xPCK (if passive matrix).
117 Max FCK is 173MHz, so this doesn't work if your PCK
