   - Apple Silicon SMC
   - TSC1641 I2C power monitor
   - MPS MP9945
   - MAX17616
   - MP2925 and MP2929

  Added support for new devices to existing drivers:
   - dell-smm: Add Dell G5 5505 to fan control whitelist
   - aspeed-g6-pwm-tach: Support for AST2700
   - asus-ec-sensors: Support for ROG STRIX X470-I GAMING, ROG STRIX
     X870-F GAMING WIFI, ROG STRIX X870E-H GAMING WIFI7, and Pro WS
     TRX50-SAGE WIFI
   - k10temp: Support for AMD Steam Deck APU ID
   - pmbus/isl68137: Support for raa229141
   - aht10: Support for dht20
   - adt7410: Support for ADT7422

   - pmbus/max34440: Support for ADPM12200
   - ntc-thermistor: Support for Murata ncp18wm474

  Infrastructure updates:
   - Utilize subsystem locking in various drivers
   - ltc4282, ltc2947: Use the new energy64 attribute

  Bug fixes:
   - Various drivers: Fixes to avoid TOCTOU, mostly in macro functions
     evaluating parameters multiple times, as well as missing locks
   - max6697: Fix regmap leak on probe failure
   - sy7636a: Fix regulator_enable resource leak on error path
   - asus-ec-sensors: Correct Pro WS TRX50-SAGE WIFI entry

  Other changes and improvements:
   - w83781d, lm78: Drop REALLY_SLOW_IO
   - Fix broken datasheet links in various drivers

  And various other minor fixes and improvements"
