From c179db3d4331db9d85c7acfdaa1e96e295d277ba Mon Sep 17 00:00:00 2001 From: Kevin O'Connor Date: Mon, 1 Nov 2021 13:54:11 -0400 Subject: temperature_sensors: Deprecate "NTC 100K beta 3950" thermistor It seems the common "beta 3950" thermistors generally follow a temperature table defined by the new "Generic 3950" definition. Using a table that actually follows the "beta 3950" temperature curve is generally less accurate. Deprecate the existing "NTC 100K beta 3950" definition to avoid this common issue.
