From 43fd0cf4c6dcd5a0e383e60168428bda0bc56374 Mon Sep 17 00:00:00 2001 From: Lukas Zapletal Date: Mon, 23 Sep 2019 12:59:31 +0200 Subject: hwmon: (k10temp) Update documentation and add temp2_input info It's been a while since the k10temp documentation has been updated. There are new CPU families supported as well as Tdie temp was added. This patch adds all missing families which I was able to find from git history and provides more info about Tctl vs Tdie exported temps.
