Pull hwmon updates from Guenter Roeck:
 "Obsolete driver removals:

   - Removed obsolete adm1021 and max6642 drivers

  New drivers:

   - MPS MP2891, MP2993, MP9941, and MP5920

   - SPD5118 (Temperature Sensor and EEPROM)

  Added device support to existing drivers:

   - g762: G761

   - dell-smm: Dell OptiPlex 7060

   - asus-ec-sensors: ProArt X670E-CREATOR WIFI

   - corsair-psu: HX1200i Series 2023 psu

   - nzxt-smart2: Additional USB IS for NZXT RGB & Fan Controller

  Notable enhancements and fixes:

   - Removed use of i2c_match_id()

   - Constified struct regmap_config where feasible

   - Cleaned up amc6821 driver, and converted to use regmap and
     with_info API

   - Converted max6639 driver to use with_info API; added support for
     additional sysfs attributes

   - Fixed various sysfs attribute underflows

   - Added PEC support to hwmon core, and use in lm90 and max31827
     drivers

  And various other minor fixes and improvements"
