From 8fee9951d30d03b4bca16c198b887c5415418c12 Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Fri, 29 Jan 2021 23:14:53 +0200 Subject: sb,soc/intel: Add wake source fields in GNVS MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For the moment, these are most not used but become a necessity for a unified approach. They would be required for the implementation of _SWS method for OSPM to determine the reason for system waking up. The related hardware registers are present with these platforms. It's expected that ACPI power-management related GNVS entries are grouped together to form a single struct in later works.
