[PATCH] omap2: fix DPLL_FREQSEL calculation

From: Felipe Balbi <hidden>
Date: 2011-01-20 11:16:54
Also in: linux-omap, lkml

Hi,

This patch fixes the calculation of the internal frequency. The value
of "n" is one less than the actual divider. 0 is a valid value.

An example where the internal frequency is calculated correctly can be
found here: clkt_dpll.c:_dpll_test_fint()

This patch is against linux-next-20110120.

scripts/get_maintainer.pl would've helped you getting a better Cc list.
I'm adding linux-omap and lakml
