Video plane scaling requires higher FCK than 101 normally. 102 103 If this is set to 0, there's no extra constraint on the 104 DISPC FCK. However, the FCK will at minimum be 105 2xPCK (if active matrix) or 3xPCK (if passive matrix). 106 107 Max FCK is 173MHz, so this doesn't work if your PCK 108 is very high. 109 110config OMAP2_DSS_SLEEP_AFTER_VENC_RESET 111 bool "Sleep 20ms after VENC reset" 112 default y 113 help 114 There is a 20ms sleep after VENC reset which seemed to fix the 115 reset. The reason for the bug is unclear, and it's also unclear 116 on what platforms this happens. 117 118 This option enables the sleep, and is enabled by default. You can 119 disable the sleep if it doesn't cause problems on your platform. 120 121endif 122
