[RFC PATCH v1 0/2] hwmon: (iio_hwmon) optionally force iio channel type

Add a devicetree binding to optionally force a different IIO channel

This is useful in cases where ADC channels are connected to a circuit
that represent another unit such as a temperature or a current.

`channel-types` was chosen instead of `io-channel-types` as this is not
part of the iio consumer bindings.

In the current form, this patch does what it's intended to do:
change the unit displayed by `sensors`, but feels like the wrong way to
address the problem.

Would it be possible to force the type of different IIO channels for
this kind of use case with a devicetree binding from the IIO subsystem?

It would be convenient to do it within the IIO subsystem to have the
right unit there too.

Thanks for your time,
