Subject: [PATCH] clk: tegra: No 7.1 super clk dividers on Tegra20
Date: Fri, 8 Feb 2013 14:44:09 +0200	[thread overview]
Message-ID: <1360327453-29242-1-git-send-email-pdeschrijver@nvidia.com> (raw)

Unlike Tegra30, Tegra20 does not have a 7.1 divider for the CPU superclk.
Remove the clocks related to the divider.
