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

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

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