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" default y help DPI Interface. This is the Parallel Display Interface. config OMAP2_DSS_VENC bool "VENC support" default y help OMAP Video Encoder support for S-Video and composite TV-out. config OMAP2_DSS_HDMI_COMMON bool config OMAP4_DSS_HDMI bool "HDMI support for OMAP4" default y select OMAP2_DSS_HDMI_COMMON help HDMI support for OMAP4 based SoCs. config OMAP4_DSS_HDMI_CEC bool "Enable HDMI CEC support for OMAP4" depends on OMAP4_DSS_HDMI select CEC_CORE default y help When selected the HDMI transmitter will support the CEC feature. config OMAP5_DSS_HDMI bool "HDMI support for OMAP5" default n select OMAP2_DSS_HDMI_COMMON help HDMI Interface for OMAP5 and similar cores. This adds the High Definition Multimedia Interface. See http://www.hdmi.org/ for HDMI specification. config OMAP2_DSS_SDI bool "SDI support" default n help SDI (Serial Display Interface) support. SDI is a high speed one-way display serial bus between the host processor and a display. config OMAP2_DSS_DSI bool "DSI support" default n select DRM_MIPI_DSI 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 http://www.mipi.org/ for DSI specifications. config 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 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. endif
