Subject: [PATCH 0/6] Add CPUidle support for Tegra210
Date: Mon, 7 Jan 2019 11:28:04 +0800 [thread overview]
Message-ID: <20190107032810.13522-1-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.
