However, the FCK will at minimum be 119 2xPCK (if active matrix) or 3xPCK (if passive matrix). 120 121 Max FCK is 173MHz, so this doesn't work if your PCK 122 is very high. 123 124config OMAP2_DSS_SLEEP_AFTER_VENC_RESET 125 bool "Sleep 20ms after VENC reset" 126 default y 127 help 128 There is a 20ms sleep after VENC reset which seemed to fix the 129 reset.
