Subject: [PATCH v2 0/2] ACPI / EC: Tune suspend/resume speed using PM operations

There are 2 improvements can be done to the EC driver to make system
suspend/resume faster:
1. Automatically use busy polling mode when noirq is entered
2. Disallow event handling (SCI_EVT/_Qxx) during suspend/resume period

This patchset achieves such performance tuning on top of a recent
workaround that creates ec_query_wq.

Lv Zheng (2):
  ACPI / EC: Add PM operations to tune polling mode efficiency
  ACPI / EC: Add PM operations to block event handling
