Video plane scaling requires higher FCK than 112 normally. 113 114 If this is set to 0, there's no extra constraint on the 115 DISPC FCK. However, the FCK will at minimum be 116 2xPCK (if active matrix) or 3xPCK (if passive matrix). 117 118 Max FCK is 173MHz, so this doesn't work if your PCK 119 is very high. 120 121config OMAP2_DSS_SLEEP_AFTER_VENC_RESET 122 bool "Sleep 20ms after VENC reset" 123 default y 124 help 125 There is a 20ms sleep after VENC reset which seemed to fix the 126 reset. The reason for the bug is unclear, and it's also unclear 127 on what platforms this happens. 128 129 This option enables the sleep, and is enabled by default. You can 130 disable the sleep if it doesn't cause problems on your platform. 131 132endif
