Alternatively, debug messages 13 can also be enabled by setting CONFIG_DYNAMIC_DEBUG and then setting 14 appropriate flags in <debugfs>/dynamic_debug/control. 15 16config OMAP2_DSS_DEBUGFS 17 bool "Debugfs filesystem support" 18 depends on DEBUG_FS 19 default n 20 help 21 This enables debugfs for OMAPDSS at <debugfs>/omapdss. This enables 22 querying about clock configuration and register configuration of dss, 23 dispc, dsi, hdmi and rfbi. 24 25config OMAP2_DSS_COLLECT_IRQ_STATS 26 bool "Collect DSS IRQ statistics" 27 depends on OMAP2_DSS_DEBUGFS 28 default n 29 help 30 Collect DSS IRQ statistics, printable via debugfs. 31 32 The statistics can be found from 33 <debugfs>/omapdss/dispc_irq for DISPC interrupts, and 34 <debugfs>/omapdss/dsi_irq for DSI interrupts. 35 36config OMAP2_DSS_DPI 37 bool "DPI support" 38 default y 39 help 40 DPI Interface.

Video plane scaling requires higher FCK than 99 normally. 100 101 If this is set to 0, there's no extra constraint on the 102 DISPC FCK. However, the FCK will at minimum be 103 2xPCK (if active matrix) or 3xPCK (if passive matrix). 104 105 Max FCK is 173MHz, so this doesn't work if your PCK 106 is very high. 107 108config OMAP2_DSS_SLEEP_AFTER_VENC_RESET 109 bool "Sleep 20ms after VENC reset" 110 default y 111 help 112 There is a 20ms sleep after VENC reset which seemed to fix the 113 reset. The reason for the bug is unclear, and it's also unclear 114 on what platforms this happens. 115 116 This option enables the sleep, and is enabled by default. You can 117 disable the sleep if it doesn't cause problems on your platform. 118 119endif 120
