Subject: [PATCH 0/7] ARM: tegra30: cpuidle: add LP2 support
Date: Mon, 8 Oct 2012 18:26:14 +0800 [thread overview]
Message-ID: <1349691981-31038-1-git-send-email-josephl@nvidia.com> (raw)
The CPU idle LP2 is a power gating idle mode for Tegra30. It supports the
secondary CPUs (i.e., CPU1-CPU3) to go into LP2 dynamically. When any of
the secondary CPUs go into LP2, it can be power gated alone. There is a
limitation on CPU0. The CPU0 can go into LP2 only when all secondary CPUs
are already in LP2. After CPU0 is in LP2, the CPU rail can be turned off.
Verified on Seaboard(Tegra20) and Cardhu(Tegra30).
This patch set should depend on these two patches:
d8be3dc ARM: tegra: rename the file of "sleep-tXX" to "sleep-tegraXX"
7dc7d51 ARM: tegra: cpuidle: replace LP3 with ARM_CPUIDLE_WFI_STATE
Joseph Lo (7):
ARM: tegra: cpuidle: separate cpuidle driver for different chips
ARM: tegra: cpuidle: add LP2 resume function
ARM: tegra30: cpuidle: add LP2 driver for secondary CPUs
ARM: tegra30: common: enable csite clock
ARM: tegra30: clocks: add CPU low-power function into
tegra_cpu_car_ops
ARM: tegra30: flowctrl: add cpu_suspend_exter/exit function
ARM: tegra30: cpuidle: add LP2 driver for CPU0
