From a1c8b34d7b1b3a8df5b86faab79010c06b037445 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Tue, 8 Sep 2015 16:12:44 -0700 Subject: skylake: Use common ACPI _SWS code Enable and use the common code for filling out the NVS data used by the _SWS methods. Add a function to provide the wake source data. With Deep S3 enabled skylake does not retain the contents of the PM1_EN register so instead just select the wake related events in PM1_STS. BUG=chrome-os-partner:40635 BRANCH=none TEST=tested on glados by checking for valid _SWS string in /sys/firmware/log after suspend/resume. Wake sources that were tested are RTC, power button, keypress, trackpad, and wifi.
