Video plane scaling requires higher FCK than 111 normally. 112 113 If this is set to 0, there's no extra constraint on the 114 DISPC FCK. However, the FCK will at minimum be 115 2xPCK (if active matrix) or 3xPCK (if passive matrix). 116 117 Max FCK is 173MHz, so this doesn't work if your PCK 118 is very high. 119 120config FB_OMAP2_DSS_SLEEP_AFTER_VENC_RESET 121 bool "Sleep 20ms after VENC reset" 122 default y 123 help 124 There is a 20ms sleep after VENC reset which seemed to fix the 125 reset.
