Subject: [PATCH] ARM: tegra: Enable CPUIdle on Tegra20
Date: Thu, 23 Feb 2012 18:20:56 +0200 [thread overview]
Message-ID: <1330014056-26125-1-git-send-email-pdeschrijver@nvidia.com> (raw)
As the LP3 code also works for Tegra20, we can enable cpuidle for Tegra20.
Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>

Tested on Tegra2 Ventana,
/sys/devices/system/cpu/cpu[0-1]/cpuidle/state0/usage increments over time
and the system is stable.
