Pull hwmon updates from Guenter Roeck:

 - Substantial rewrite of lm90 driver to support several additional
   chips and improve support for existing chips.

 - Add support of ROG ZENITH II EXTREME, Maximus XI Hero, and
   Strix Z690-a D4 to asus-ec-sensors driver

 - Add support of F71858AD to f71882fg driver

 - Add support of Aquacomputer Quadro to aquacomputer_d5next driver

 - Improved assembler code and add support for Dell G5 5590 as well as
   XPS 13 7390 in dell-smm driver

 - Add support for ASUS TUF GAMING B550-PLUS WIFI II to nct775 driver

 - Add support for IEEE 754 half precision to PMBus core. Also support
   for Analog Devices LT7182S, improve regulator support, and report
   various MFR register values in debugfs.

 - Various other minor improvements and fixes
