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

52 DBI is a bus between the host processor and a peripheral,
53 such as a display or a framebuffer chip.

93config OMAP2_DSS_FAKE_VSYNC

96 help
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,
100 time animation.

105 default 0
106 help
107 This can be used to adjust the minimum FCK/PCK ratio.
108
109 With this you can make sure that DISPC FCK is at least
110 n x PCK. Video plane scaling requires higher FCK than
111 normally.
112
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).
116
117 Max FCK is 173MHz, so this doesn't work if your PCK
118 is very high.
