From 5625dace84929b0fb6d3feb2bceda9dd0d5bb087 Mon Sep 17 00:00:00 2001 From: Tim Wawrzynczak Date: Wed, 27 Jul 2022 10:09:04 -0600 Subject: mb/google/brya/acpi: Add L23 entry/exit sequences during dGPU GCOFF When the dGPU is entering GCOFF, the link should first be placed into L2/L3 as appropriate for the design, then when exiting, the link should be placed back into L0. This patch fixes that oversight.
