From 0bbb0fcf5ff16061ae7b5f182a5803020df65c9a Mon Sep 17 00:00:00 2001 From: Aseda Aboagye Date: Wed, 17 Jul 2019 10:36:10 -0700 Subject: google/nocturne: Add MKBP events as a wake source We would like to wake nocturne up in suspend from an MKBP event. On Nocturne, MKBP events are notified to the host via a GPIO from the EC, EC_INT_L. However, the AP cannot wake from suspend from this GPIO. Therefore, we'll use the host event interface to wake the system instead. This commit simply enables MKBP events to wake the system in suspend. BUG=chromium:786721 BRANCH=firmware-nocturne-10984.B TEST=Build and flash nocturne, generate MKBP events on the EC and verify that the system wakes up in suspend.
