From 38ecf1e5f47167ae48ef31a1fd1fbbe9562eff2b Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 28 Nov 2018 18:19:55 +0100 Subject: [PATCH] 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.
