Pull hwmon updates from Guenter Roeck:
 "New driver:

   - Maxim MAX6620

  Notable functional enhancements:

   - Add Asus WMI support to nct6775 driver, and list boards supporting
     it

   - Move TMP461 support from tm401 driver to lm90 driver

   - Add support for fanX_min, fanX_max and fanX_target to dell-smm
     driver, and clean it up while doing so

   - Extend mlxreg-fan driver to support multiple cooling devices and
     multiple PWM channels. Also increase number of supported fan
     tachometers.

   - Add a new customer ID (for ASRock) to nct6683 driver

   - Make temperature/voltage sensors on nct7802 configurable

   - Add mfg_id debugfs entry to pmbus/ibm-cffps driver

   - Support configurable sense resistor values in pmbus/lm25066, and
     fix various coefficients

   - Use generic notification mechanism in raspberrypi driver

  Notable cleanups:

   - Convert various devicetree bindings to dtschema, and add missing
     bindings

   - Convert i5500_temp and tmp103 drivers to
     devm_hwmon_device_register_with_info

   - Clean up non-bool "valid" data fields

   - Improve devicetree configurability for tmp421 driver"

+description: |
+  Thermistors with negative temperature coefficient (NTC) are resistors that
+  vary in resistance in an often non-linear way in relation to temperature.
+  The negative temperature coefficient means that the resistance decreases
+  as the temperature rises. Since the relationship between resistance and
+  temperature is non-linear, software drivers most often need to use a look
+  up table and interpolation to get from resistance to temperature.
+
+  When used in practice, a thermistor is often connected between ground, a
+  pull-up resistor or/and a pull-down resistor and a fixed voltage like this:
+
+      + e.g. 5V = pull-up voltage (puv)
+      |
+     +-+
+     | |
+     | | Pull-up resistor
+     | | (puo)
+     +-+
+      |-------------------------o
+     +-+ |                      ^
+     | |/                       |
