From a7b60e7dc8788db5de2fe983e9702e167b7f27fe Mon Sep 17 00:00:00 2001 From: Tim Wawrzynczak Date: Tue, 10 Nov 2020 09:57:19 -0700 Subject: soc/intel/tigerlake: Check TBT & TCSS ports for wake events Wakes from TBT ports and TCSS devices will show up as PME_B0_STS wakes, so add checks for wakes from these devices in pch_log_pme_internal_wake_source.
