[PATCH v3 0/4] hwmon: Add support for INA780

[Chris Packham <chris.packham@alliedtelesis.co.nz>]

This series adds support for the INA780 to the existing ina238.c driver.

v2: https://lore.kernel.org/linux-hwmon/20250808030510.552724-1-chris.packham@alliedtelesis.co.nz/
v1: https://lore.kernel.org/linux-hwmon/20250806005127.542298-1-chris.packham@alliedtelesis.co.nz/

One important bit of feedback I've not addressed is this

> Follow-up: I ordered evaluation boards for INA228, INA237, INA238, and INA780A.
> I'll want to see support added for current limits on all chips, using a similar
> approach as the one in the ina2xx driver. After all, the shunt voltage limits
> are really current limits in disguise. With that and appropriate chip specific
> parameters the differences between the chips should become relatively minor.
>
> This should also simplify adding support for INA700 which seems similar to INA780A.

I wasn't sure if that meant you were going to look at adding current limits to
the existing chips and I should wait or if you wanted me to try based on the
code. Given our timezone differences I figured I'd send the series anyway.
Patch 2 is a bugfix that you might want to pick up sooner.
