Subject: [PATCH 7/7] clk: tegra: use max divider if divider overflows
Date: Thu, 26 Dec 2013 16:44:27 -0800	[thread overview]
Message-ID: <1388105067-24438-8-git-send-email-abrestic@chromium.org> (raw)
In-Reply-To: <1388105067-24438-1-git-send-email-abrestic@chromium.org>

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.
