+ bool "Debug support"
+ help
+ This enables printing of debug messages. Alternatively, debug messages
+ can also be enabled by setting CONFIG_DYNAMIC_DEBUG and then setting
+ appropriate flags in <debugfs>/dynamic_debug/control.
+
+config FB_OMAP2_DSS_DEBUGFS
+ bool "Debugfs filesystem support"
+ depends on DEBUG_FS
+ help
+ This enables debugfs for OMAPDSS at <debugfs>/omapdss. This enables
+ querying about clock configuration and register configuration of dss,
+ dispc, dsi, hdmi and rfbi.

+ Collect DSS IRQ statistics, printable via debugfs.
+
+ The statistics can be found from
+ <debugfs>/omapdss/dispc_irq for DISPC interrupts, and
+ <debugfs>/omapdss/dsi_irq for DSI interrupts.

+ SDI is a high speed one-way display serial bus between the host

+config FB_OMAP2_DSS_DSI
+ bool "DSI support"
+ 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 https://www.mipi.org/ for DSI specifications.
+
+config FB_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.
+
+config FB_OMAP2_DSS_SLEEP_AFTER_VENC_RESET
+ bool "Sleep 20ms after VENC reset"
+ default y
+ help
+ There is a 20ms sleep after VENC reset which seemed to fix the
+ reset. The reason for the bug is unclear, and it's also unclear
+ on what platforms this happens.
+
+ This option enables the sleep, and is enabled by default. You can
+ disable the sleep if it doesn't cause problems on your platform.
