Subject: [PATCH v7 14/16] ARM: tegra: Add entries for cpufreq on Tegra124
Date: Thu,  8 Jan 2015 15:22:17 +0200	[thread overview]
Message-ID: <1420723339-30735-15-git-send-email-mikko.perttunen@kapsi.fi> (raw)
In-Reply-To: <1420723339-30735-1-git-send-email-mikko.perttunen@kapsi.fi>

From: Tuomas Tynkkynen <ttynkkynen@nvidia.com>

The Tegra124 cpufreq driver relies on certain clocks being present
in the /cpus/cpu@0 node.
