Subject: [PATCH v2 5/5] hwmon: (k10temp) Don't show temperature limits on Ryzen (Zen) CPUs
Date:   Sat, 18 Jan 2020 09:26:15 -0800
Message-Id: <20200118172615.26329-6-linux@roeck-us.net>
In-Reply-To: <20200118172615.26329-1-linux@roeck-us.net>
References: <20200118172615.26329-1-linux@roeck-us.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The maximum Tdie or Tctl is not published for Ryzen CPUs. What is
known, however, is that the traditional value of 70 degrees C is no
longer correct. Displaying it is meaningless, confusing, and wrong.
Stop doing it.
