95 | default 0 | |
96 | help | |
97 | This can be used to adjust the minimum FCK/PCK ratio. | |
98 | ||
99 | With this you can make sure that DISPC FCK is at least | |
100 | n x PCK. Video plane scaling requires higher FCK than | |
101 | normally. | |
102 | ||
103 | If this is set to 0, there's no extra constraint on the | |
104 | DISPC FCK. However, the FCK will at minimum be | |
105 | 2xPCK (if active matrix) or 3xPCK (if passive matrix). | |
106 | ||
107 | Max FCK is 173MHz, so this doesn't work if your PCK | |
108 | is very high. | |

114 | There is a 20ms sleep after VENC reset which seemed to fix the | |

116 | on what platforms this happens. | |

118 | This option enables the sleep, and is enabled by default. You can | |
119 | disable the sleep if it doesn't cause problems on your platform. | |
