From 311abbd8896a927b7c4a4b2a226060a5ed64b044 Mon Sep 17 00:00:00 2001 From: Alec Berg Date: Fri, 14 Mar 2014 09:27:31 -0700 Subject: rambi: glimmer: Disable key scanning in suspend when lid is open Added ability to disable the keyboard to wake from suspend when the lid is outside a certain angle range. This has been added to glimmer by defining CONFIG_LID_ANGLE_KEY_SCAN in its board.h. Also modified the lid angle calculation to include a reliability flag which can be used to tell when the hinge aligns too closely with gravity and the lid angle value is unreliable. BUG=none BRANCH=rambi TEST=Tested on a glimmer: In S3, verified that when the lid is open past ~180 deg, the keyboard does not wake the machine. Also verified that if you align hinge with gravity, the keyboard enabled/disabled status remains the same (since we can't actually trust the lid angle value).
