CONFIG_FB_OMAP2_DSS_MIN_FCK_PER_PCK: Minimum FCK/PCK ratio (for scaling)

General informations

The Linux kernel configuration item CONFIG_FB_OMAP2_DSS_MIN_FCK_PER_PCK:

Help text

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.
