[PATCH v4 0/4] hwmon: (sht3x) Add support for GXCAS GXHT30

From: Zaixiang Xu

Date: Wed Mar 25 2026 - 05:12:46 EST


This series adds support for the GXCAS GXHT30 humidity and temperature
sensor. The GXHT30 is software compatible with the Sensirion SHT30 series.

This series also introduces the missing YAML binding schema for the
Sensirion SHT30 family, replacing wildcards with specific model names.

Changes in v4:
- Use match data (.data) to correctly distinguish between SHT (humidity/
temperature) and STS (temperature-only) sensors in the driver, fixing
a logic error where STS sensors would report bogus humidity
(suggested by Guenter Roeck and AI review).
- Update YAML bindings to use fallback compatibles for compatible chips
and add optional 'interrupts' and 'vdd-supply' properties
(suggested by Guenter Roeck and AI review).
- Simplified of_match_table to only include base models due to the
newly added fallback mechanism.
- Renamed binding file from sensirion,sht3x.yaml to sensirion,sht30.yaml.
- Include Conor's Acked-by for the vendor-prefix patch.

Changes in v3:
- Split driver changes into two patches: one for DT framework and one
for adding GXHT30 (suggested by Guenter Roeck).
- Fixed commit message line lengths (suggested by Guenter Roeck).
- Removed wildcards 'x' from compatibles and used specific model names
(suggested by Conor Dooley).
- Added manufacturer website to vendor-prefix patch (suggested by Conor Dooley).
- Fixed missing newline at end of YAML file (reported by kernel test robot).

Changes in v2:
- Fix placeholder "Your Name" in MODULE_AUTHOR.
