dd6478d68b w1: add DS2405 addressable switch driver
This adds a driver for a DS2405 1-wire single-channel addressable switch.
The DS2405 can also work as a single-channel binary remote sensor.

This driver supports two attributes: "state" and "output" which are the
same attribute names as supported by existing DS2406, DS2408 and DS2413
drivers.

94859308a2 w1: new w1_ds2406 driver
Some preliminary work at making use of this driver led me to implement
CRC-16 checks on read and write to deal with the occasional glitchiness of
the 1-Wire bus.  The revised driver (attached) returns an I/O error if the
CRC check fails.  When reading the chip's state, either you get a valid
indication or you get an I/O error.  When changing its state, either the
change is successful or an I/O error is returned.

275ac74629 w1: add Maxim/Dallas DS2780 Stand-Alone Fuel Gauge IC support
Add support for the Maxim/Dallas DS2780 Stand-Alone Fuel Gauge IC.

It was suggested to combine this functionality with the current ds2782
driver.  Unfortunately, I'm unable to commit the time to refactoring this
driver to that extent and I don't have a platform with the ds2782 part to
validate that there are no regression issues by adding this functionality.

17fecb5582 w1: DS2423 counter driver and documentation
This is a 1-wire/w1 DS2423 slave driver for reading the values from all 4
counters available DS2423 devices by using standard w1_slave file.  In
ds2423 the counters are tied to ram pages 12-15 in and each of those
ram-pages.  Each of these counter values (and asoociated ram page values)
are represented as a own line in w1_slave file.  Driver has been tested on
mips and x86.

usage example:
cat /sys/bus/w1/devices/1d-00000009b964/w1_slave
