From b047c62e24418b9f62b721be017ec5c0364166a5 Mon Sep 17 00:00:00 2001 From: Aaron Ma Date: Tue, 31 Jul 2018 18:52:39 +0800 Subject: ACPI / EC: Use ec_no_wakeup on ThinkPad X1 Yoga 3rd Like on X1C6, on X1Y3 EC interrupts constantly wake up system from s2idle, the power consumption is extremely high. So make ec_no_wakeup be true as default to keep system in s2idle mode and reduce power consumption. Power button works when ec_no_wakeup=true. Signed-off-by: Aaron Ma Signed-off-by: Rafael J.
