[PATCH v2 0/4] ACPI / EC: Fix ECDT and boot_ec support

[Lv Zheng]

Linux uses ECDT only in boot stage (before the namespace is fully
initialized), but there are cases reported that Windows allows ECDT to be
used for OSPM runtime, responding EC events by evaluating _Qxx methods
under the device node indicated in the ECDT.

This patchset changes Linux ECDT support to follow Windows behavior and
also fixes related boot_ec support.

v2:
 Rebased on top of recent linux-pm.git/linux-next.
 Addressed 1 comment from Peter Wu.
 Update patch SOBs.
