In the S0 <-> S3 transition, Coreboot sends EC messages to set/clear the wake masks when the SMI is invoked. For S0ix, EC sets and clears the wake mask via this patch. These functions are directly invoked from the state machine transition states. During S0ix entry, the wake mask for lid open is enabled. During S0ix exit, the wake mask for lid open is cleared. All pending events are also cleared BRANCH=none BUG=chrome-os-partner:48834 TEST=test lidopen in S0ix Signed-off-by: Archana Patni <archana.patni@intel.com> Signed-off-by: Subramony Sesha <subramony.sesha@intel.com> Change-Id: I52a15f502ef637f7b7e4b559820deecb831d818f Reviewed-on: https://chromium-review.googlesource.com/320190 Commit-Ready: Divya Jyothi <divya.jyothi@intel.com> Tested-by: Divya Jyothi <divya.jyothi@intel.com> Reviewed-by: Shawn N <shawnn@chromium.org>
