From 45b9509476c920ffc0f83543a7175985b229f8b1 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Thu, 30 Mar 2023 13:43:11 -0600 Subject: [PATCH] mb/google/skyrim: Disable L1.2 for SD port Having L1.2 enabled on the SD port increases the kernel resume times by between 30 & 40ms. This patch disables L1.2 on SD to get that time back. As with needing to have hotplug enabled on the SD card, this seems like a driver issue, so hopefully that will get sorted out and this patch can be reverted. BUG=b:274025743 TEST=resume times are decreased.
