[PATCH v3] arm64: dts: exynos7: add support for cpuidle core power down

2014-11-05 Thread Chander Kashyap
Exynos7 has core power down state where cores can be powered off independently. This patch adds support for this state. Entry latency for the core power down is calculated as follows: 1. Time difference is measured between cpuidle entry and exit. 2. WFI is skipped measuring the time. 3. The time
