[PATCH 7/7] clk: tegra: use max divider if divider overflows

STALE4645d

From: Andrew Bresticker <hidden>
Date: 2013-12-27 00:51:09
Also in: linux-tegra, lkml
Subsystem: common clk framework, tegra clock driver, the rest · Maintainers: Stephen Boyd, Brian Masney, Jerome Brunet, Prashant Gaikwad, Linus Torvalds

When requesting a rate less than the minimum clock rate for a divider,
use the maximum divider value instead of bailing out with an error.
This matches the behavior of the generic clock divider.
