1 config FB_OMAP2_DSS_INIT
6 select VIDEOMODE_HELPERS
7 select FB_OMAP2_DSS_INIT
10 config FB_OMAP2_DSS_DEBUG
14 This enables printing of debug messages. Alternatively, debug messages
15 can also be enabled by setting CONFIG_DYNAMIC_DEBUG and then setting
16 appropriate flags in <debugfs>/dynamic_debug/control.
18 config FB_OMAP2_DSS_DEBUGFS
19 bool "Debugfs filesystem support"
23 This enables debugfs for OMAPDSS at <debugfs>/omapdss. This enables
24 querying about clock configuration and register configuration of dss,
25 dispc, dsi, hdmi and rfbi.
27 config FB_OMAP2_DSS_COLLECT_IRQ_STATS
28 bool "Collect DSS IRQ statistics"
29 depends on FB_OMAP2_DSS_DEBUGFS
32 Collect DSS IRQ statistics, printable via debugfs.
34 The statistics can be found from
35 <debugfs>/omapdss/dispc_irq for DISPC interrupts, and
36 <debugfs>/omapdss/dsi_irq for DSI interrupts.
38 config FB_OMAP2_DSS_DPI
42 DPI Interface. This is the Parallel Display Interface.
44 config FB_OMAP2_DSS_RFBI
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 specifications.
57 config FB_OMAP2_DSS_VENC
61 OMAP Video Encoder support for S-Video and composite TV-out.
63 config FB_OMAP2_DSS_HDMI_COMMON
66 config FB_OMAP4_DSS_HDMI
67 bool "HDMI support for OMAP4"
69 select FB_OMAP2_DSS_HDMI_COMMON
71 HDMI support for OMAP4 based SoCs.
73 config FB_OMAP5_DSS_HDMI
74 bool "HDMI support for OMAP5"
76 select FB_OMAP2_DSS_HDMI_COMMON
78 HDMI Interface for OMAP5 and similar cores. This adds the High
79 Definition Multimedia Interface. See http://www.hdmi.org/ for HDMI
82 config FB_OMAP2_DSS_SDI
86 SDI (Serial Display Interface) support.
88 SDI is a high speed one-way display serial bus between the host
89 processor and a display.
91 config FB_OMAP2_DSS_DSI
95 MIPI DSI (Display Serial Interface) support.
97 DSI is a high speed half-duplex serial interface between the host
98 processor and a peripheral, such as a display or a framebuffer chip.
100 See http://www.mipi.org/ for DSI specifications.
102 config FB_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
120 config FB_OMAP2_DSS_SLEEP_AFTER_VENC_RESET
121 bool "Sleep 20ms after VENC reset"
124 There is a 20ms sleep after VENC reset which seemed to fix the
125 reset. The reason for the bug is unclear, and it's also unclear
126 on what platforms this happens.
128 This option enables the sleep, and is enabled by default. You can
129 disable the sleep if it doesn't cause problems on your platform.
