Subject: arm64: tegra: Enable PMC wake events on Tegra194
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=38ecf1e5f47167ae48ef31a1fd1fbbe9562eff2b;p=linux.git

arm64: tegra: Enable PMC wake events on Tegra194

Wake events are a feature that allows the interrupt and GPIO controllers
to be powered off as part of system sleep. The PMC which is always on is
monitoring these wake events and can power up subsequent controllers as
necessary to process them.
