This mbox contains three revisions (v2, v3, v4) of a single documentation-only patch for the xe hwmon driver. The patch documents a known DG2 hardware quirk where the second fan channel (`fan2_input`) may read 0 RPM due to shared tach wiring, and explains why this is not a driver bug.

The series shows good iterative refinement following reviewer feedback:
- **v1** (not in mbox): attempted a code change to reduce the reported fan count on DG2.
- **v2**: dropped the code change, added a dedicated `Documentation/gpu/xe/xe_hwmon.rst` doc instead.
- **v3**: dropped the standalone doc file; added a short note directly under the `fan2_input` ABI entry per Raag's feedback.
- **v4**: identical diff to v3, but adds a `Fixes:` tag and collects `Reviewed-by` from Raag Jadav.

**v4 is the latest and should be the one considered for merge.** It is a clean, minimal documentation addition. The patch is correct, well-scoped, and already has a Reviewed-by.

**Verdict: v4 looks good to merge.** One minor observation below but nothing blocking.
