Subject: [PATCH v3 0/5] hwmon: it87: prep for IT8613E support

This series ports IT8613E support from the out-of-tree it87 fork into
upstream in small steps. It first adds per-chip resource metadata and
new PWM temp map handling, then expands temp limits/offsets, adds
IT8613E detection, and finally the IT8613E configuration.

Tested on: IT8613E, MEDION B660H7-M20 BIOS motherboard.

Changes in v3:
- Send as a proper patch series (maintainer request).
- Fix smatch warning in show_pwm_temp_map() (IS_ERR check before use).
- PWM control fixes based on fork diff:
  - Use IT8613E PWM register table (and it8622 for future extension).
  - Clamp invalid PWM temp map values when reading.
  - Default new-tempmap PWM mapping to channel 0.
