Subject: [PATCH v3 0/4] hwmon: (ltc2945): add support for sense resistor

Changeset adds support for sense resistor.

Changelog v2 -> v3:
* https://lore.kernel.org/linux-hwmon/20201111091259.46773-1-alexandru.ardelean@analog.com/
* dropped patch 'docs: hwmon: (ltc2945): change type of val to ULL in ltc2945_val_to_reg()'
* add patch 'hwmon: (ltc2945): clamp values before converting'
* for patch 'hwmon: (ltc2945): add support for sense resistor'
  - sense-resistor is represented in milli-ohms internally; this
    risks of any other potential overflows with the multiplication to
    1000; the scaling in the driver becomes simpler, but we can't allow
    a lower resistor value that 1 mOhm, and all resistor values
    need to be integer in mOhm.
  - added max power and max amps limits, adjusted to sense resistor
* for patch 'dt-bindings: hwmon: ltc2945: add device tree doc for ltc2945 '
  added 'Reviewed-by: Rob Herring <robh@...nel.org>'
