Subject: [PATCH V2 0/6] Add CPUidle support for Tegra210
Date: Mon, 28 Jan 2019 17:18:09 +0800	[thread overview]
Message-ID: <20190128091815.7040-1-josephl@nvidia.com> (raw)

This patch series adds CPUidle support for Tegra210, which supports
power-down state (C7) for CPU cores. And due to arch timer cannot work
across CPU core power-down and power on reset signal event. We introduce
Tegra210 timer driver to work as clock event device. So it can be the
wake-up source of CPU cores when they idled in the power-down state.

Fixed in V2:
 * list all the timer IRQs in the binding doc and dts file
 * add error clean-up code in timer driver
 * add entry-latency-us and exit-latency-us properties for idle-states
   DT node
