Hi Laurent,
Thank you for taking the time to reply to my patch and to my earlier
questions.

Can you explain the benefits of profiling this inside the kernel rath
Hi Sakari,
Thank you for taking the time to look into the issue.

Clock frequencies are not exact values, but rather imprecise, physical
properties. The present pll computation however, treats them as exact.
It tries to compute parameters that attain the requested pix_clock
exactly. Failing that, it gives up.
The new implementation approximates the requested pix
