[PATCH v4 0/3] hwmon: Add support for the LTC4283 Hot Swap Controller

["Nuno Sá via B4 Relay" <devnull+nuno.sa.analog.com@kernel.org>]

This is v3 for the LTC4283 how swap controller. Main change is that I'm
now using the auxiliary bus for adding the GPIO device (done depending
on FW properties).

Similar to the LTC4282 device, we're clearing some fault logs in the
reset_history attributes.

Guenter, in [1] you can find some replies for some questions you had in
v2 that likely you don't remember anymore.

v4 is based in last linux-next (next-20251204) so that we get
field_prep()/get() for masks that are not compile time constants.
