From e78acf7efebff9184ad4add02b62a1f486a8cde8 Mon Sep 17 00:00:00 2001 From: Andres Freund Date: Fri, 13 Nov 2020 12:49:16 -0800 Subject: thermal: intel_pch_thermal: Add PCI ids for Lewisburg PCH. I noticed that I couldn't read the PCH temperature on my workstation (C620 series chipset, w/ 2x Xeon Gold 5215 CPUs) directly, but had to go through IPMI. Looking at the data sheet, it looks to me like the existing intel PCH thermal driver should work without changes for Lewisburg. I suspect there's some other PCI IDs missing. But I hope somebody at Intel would have an easier time figuring that out than I...
