	  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 OMAP2_DSS_DEBUGFS
	bool "Debugfs filesystem support"
	depends on DEBUG_FS
	default n
	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.

config OMAP2_DSS_COLLECT_IRQ_STATS
	bool "Collect DSS IRQ statistics"
	depends on OMAP2_DSS_DEBUGFS
	default n
	help
	  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.

config OMAP2_DSS_DPI
	bool "DPI support"

	help
	  DPI Interface. This is the Parallel Display Interface.

config OMAP2_DSS_VENC
	bool "VENC support"
