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:
v10 -> v11: No change.
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.

Wasn't this applied? Why do you send it again?

Best regards,

There was a problem reported in the driver implementation
(bad compatible entry). The submitter chose to send
v11 instead of a patch fixing the already applied driver.

I'll fix up the original driver patch instead. Please ignore.
