Subject: [PATCH v4 0/5] hwmon: it87: add 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.

Builds: each patch builds cleanly with W=1
(the only checkpatch warnings are the kept symbolic perms
S_IRUGO | S_IWUSR / S_IRUGO).

Changes in v4:
- Drop FEAT_TEMP_OFFSET and has_temp_offset(); rely on num_temp_offset.
- Initialize num_temp_limit/offset/map for all chips, no runtime defaults.
- Use per-chip reg_pwm pointer instead of type checks; fixes compile error.
- Keep IT8613E feature set aligned with the above (no FEAT_TEMP_OFFSET).

benoit.masson (5):
  hwmon: it87: describe per-chip temperature resources
  hwmon: it87: prepare for extended PWM temp maps
  hwmon: it87: expose additional temperature limits
  hwmon: it87: add IT8613E identification
  hwmon: it87: add IT8613E configuration
