From 5145e23a3510b6c6129b5e8aa56876fcfcb1adb6 Mon Sep 17 00:00:00 2001 From: Tim Wawrzynczak Date: Tue, 3 Nov 2020 13:24:14 -0700 Subject: soc/intel/jasperlake: Add PCH PCIe RPs wake up events to event log All wakes by a PCH PCIe root port were lumped under one event source; this commit splits them up so each root port gets its own ID in the event log.
