Thanks.
After investigating the issue further it seems that I had it
backwards. The value of "n" is the value to divide by, not the value
that goes in the register. This means that it is _dpll_test_fint()
that is doing it incorrectly. Here is a new version of the patch to
fix the right function.
This patch fixes the calculation of the internal frequency. The value
of "n" is the actual divider to use.
This patch is against linux-next-20110120.
