[PATCH 1/2] device-tree: bindinds: add NXP PCT2075 as compatible device to LM75

[Daniel Mack]

The PCT2075 is compatible to other chips that are already handled by
the LM75 driver.

[PATCH 2/2] drivers: hwmon: lm75: add support for PCT2075

[Daniel Mack]

The NXP PCT2075 is largely compatible with other chips already supported
by the LM75 driver. It uses an 11-bit resolution and defaults to 100 ms
sampling period. The datasheet is here:

Applied to hwmon-next. Note that I also updated Documentation/hwmon/lm75.rst.
