Subject: [RFC PATCH 0/3] ACPI / PM: Move _PTS/_WAK invocations out of the noirq stage

Currently _PTS/_WAK are invoked during noirq stages, while in _PTS/_WAK,
there can be EC transactions. Though the EC driver is able to handle
transactions using polling mode, for the performance reason, it is better
to move _PTS/_WAK out of the noirq stage.

Lv Zheng (3):
  PM: Rename prepare_late/wake suspend_ops callbacks to
    prepare_noirq/finish_noirq
  PM: Add prepare_late/finish_early suspend_ops callbacks
  ACPI / PM: Fix EC polling issue by implementing
    prepare_late/finish_early suspend_ops callbacks
