From 3f06e6c74089a1dffcf9340890c7b5bb10ea2119 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Sun, 18 Feb 2024 12:31:13 -0600 Subject: mb/google/volteer: Disable PM ACPI timer to fix S0i3 regression Keeping the PM timer enabled will disqualify an ADL system from entering S0i3, and will also cause an increase in power during suspend states. The PM timer is not required for brya boards, therefore disabling it. Fixes: 0e90580 (soc/intel: transition full control over PM Timer from FSP to coreboot) This mirrors an identical commit for google/brya: 1ce0f3aab72d ("mb/google/brya: Fix S0i3 regression") TEST=Boot Linux on google/drobit, verify S0i3 counter incrementing after exiting S0ix suspend states.
