However, the FCK will at minimum be 120 2xPCK (if active matrix) or 3xPCK (if passive matrix). 121 122 Max FCK is 173MHz, so this doesn't work if your PCK 123 is very high. 124 125config OMAP2_DSS_SLEEP_AFTER_VENC_RESET 126 bool "Sleep 20ms after VENC reset" 127 default y 128 help 129 There is a 20ms sleep after VENC reset which seemed to fix the 130 reset.
