From 47da16dc335bf36496919d89a015852f1590fc5c Mon Sep 17 00:00:00 2001 From: Kevin Chiu Date: Tue, 22 Mar 2022 14:04:14 +0800 Subject: mb/google/guybrush/var/nipperkin: update telemetry settings Update the two load line slope settings for the telemetry. AGESA sends these values to the SMU, which accepts them as units of current. Proper calibration is determined by the AMD SDLE tool and the Stardust test.
