[PATCH v2 0/4] hwmon: (ltc2945): add support for sense resistor

[Alexandru Ardelean]

This changeset adds support the sense resistor that can be connected on
a board to computer current & power.

The sense resistor is a parameter of the board. It should be configured in
the driver via a device-tree / ACPI property, so that the proper current
measurements can be done in the driver.

Changelog v1 -> v2:
* https://lore.kernel.org/linux-hwmon/20201106101825.30960-1-alexandru.ardelean@xxxxxxxxxx/
* reverted kstrotoull() -> kstrtoul()
* added sanity check for resistor, to prevent crashing when DT provides
  zero value
* add DT binding doc for ltc2945
