[PATCH 0/2] hwmon: lm90: Fix DT channel constraints and reject unsupported channel 2

[Flaviu Nistor <flaviu.nistor@gmail.com>]

The intention of this patch series is to fix DT channel constrains in the
dt-bindings and inprove the driver to reject unsupported channel 2.

dt-bindings:
Forbid temperature-offset-millicelsius on channel@0 (local sensor).
Rejecting of assigning temperature-offset-millicelsius for channel@0 is
already implemented in the driver.
Reject channel@2 for compatibles that have only one remote sensor.

driver:
If the sensor have only one remote channel, reject a possible unsupported
channel 2 and return an error, similar to miss-assigment of temperature
-offset-millicelsius property to channel@0.

    temperature offset
  hwmon: (lm90) Reject channel 2 on chips with only one remote sensor
