Looks like this got lost somewhere? It does no longer apply, is it possible to do a respin ?

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 id's missing. But I hope somebody at Intel would have an easier time figuring that out than I...
