[PATCH 1/2] soc/tegra: pmc: Enable PMIC wake event on Tegra186

[PATCH 1/2] soc/tegra: pmc: Enable PMIC wake event on Tegra186

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

The PMIC wake event can be used to bring the system out of suspend based
on certain events happening on the PMIC (such as an RTC alarm).

[PATCH 2/2] arm64: tegra: Make the RTC a wakeup source on Jetson TX2

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

The RTC found on the MAX77620 PMIC can be used as a wakeup source on
Jetson TX2, which is useful to wake the system from suspend at a given
time.
