Subject: [PATCH 2/6] ARM: Tegra: Add CPU's OPPs for using cpufreq-cpu0 driver
Date: Wed,  7 Aug 2013 20:16:44 +0530	[thread overview]
Message-ID: <d4cd498d9b63d761039b025216e65278dc8e0e37.1375886595.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 needs OPPs to be present in DT which can be probed by it to
get frequency table. This patch adds OPPs and clock-latency to tegra cpu0 node
for multiple SoCs.

Voltage levels aren't used until now for tegra and so a flat value which would
eventually be ignored is used to represent voltage.
