Subject: [PATCH 0/3] hwmon: (ctf2301) Add support for CTF2301

Sensylink CTF2301 is a system-level thermal management solution chip.

The CTF2301 is an I2C/SMBus compatible device featuring:
  - One local temperature sensor with ±0.5°C accuracy and 0.0625°C resolution.
  - One remote temperature sensor for external diode-connected transistors,
    offering ±1°C accuracy and 0.125°C resolution (temperature range: -40°C to +125°C).
  - An integrated PWM fan controller capable of operating in two modes:
      1. Direct-DCY: Open-loop direct duty cycle control.
      2. Auto-Temp: Closed-loop automatic fan speed control based on measured temperature.
  - A 1-channel fan speed monitor (TACH input) for RPM measurement.

Check CTF2301 datasheet for more details[1]
