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
