Subject: [PATCH 5/6] ARM: Tegra: start using cpufreq-cpu0 driver
Date: Wed,  7 Aug 2013 20:16:47 +0530	[thread overview]
Message-ID: <6610c86618b781b00eba446ca19035e077d99691.1375886595.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1375886595.git.viresh.kumar@linaro.org>
In-Reply-To: <cover.1375886595.git.viresh.kumar@linaro.org>

cpufreq-cpu0 driver can be probed over DT only if a corresponding device node is
created for the SoC which wants to use it. Lets create a platform device for
cpufreq-cpu0 driver for Tegra.

Also it removes the Kconfig entry responsible to compiling tegra-cpufreq driver
and hence there will not be any conflicts between two cpufreq drivers.
