Subject: [PATCH v10 1/2] dt-bindings: hwmon: add MAX31827
Date: Wed, 24 May 2023 19:01:29 +0300 [thread overview]
Message-ID: <20230524160131.14081-1-daniel.matyas@analog.com> (raw)
MAX31827 is a low-power temperature switch with I2C interface.
The device is a ±1°C accuracy from -40°C to +125°C
(12 bits) local temperature switch and sensor with I2C/SM-
Bus interface. The combination of small 6-bump wafer-lev-
el package (WLP) and high accuracy makes this temper-
ature sensor/switch ideal for a wide range of applications.

Change log:
v9 -> v10: Added proper change log.
v8 -> v9: Did not use '--base'.
v7 -> v8: Added '--base=[Linux 6.4-rc1 commmit]' when using 'git format-patch'
v6 -> v7: No change.
v5 -> v6: Added Reviewed-by tag.
v3 -> v5: Forgot to add Reviewed-by tag.
v2 -> v3: Made max31828 and max31829 compatible with max31827.
v1 -> v2: Resolved dt_binding_check errors. Dropped status at i2c node. Made node name generic.
