Subject: [PATCH v2 0/4] hwmon: (ltc2945): add support for sense resistor
Date: Wed, 11 Nov 2020 11:12:55 +0200 [thread overview]
Message-ID: <20201111091259.46773-1-alexandru.ardelean@analog.com> (raw)
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@analog.com/
* reverted kstrotoull() -> kstrtoul()
* added sanity check for resistor, to prevent crashing when DT provides
zero value
* add DT binding doc for ltc2945
