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 FB_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.
