Do you have a system that needs this?

Yah, we have a system (Cygnus) that can either use the HCLK, or an external
clock generated from a PLL. To get certain pixel clock frequencies
(depending on the LCD panel we use), we need to use the external clock
source with the PLL configured to a particular VCO frequency.

We have not enabled full LCD/video support on that platform in the mainline
kernel, but we'll eventually get to it.

OK I hope to finish these patches soon so you have some nice stuff
to build upon. I guess it will need the same per-vendor plug-in that
I supplied for the ARMs and the Nomadik.

Yours,
