drivers/power/ds2780_battery.c: add a nolock function to w1 interface

Adds a nolock function to the w1 interface to avoid locking the
mutex if needed.

w1: ds2760 and ds2780, use ida for id and ida_simple_get() to get it

2011-11-02T23:07:02+00:00

Straightforward.  As an aside, the ida_init calls are not needed as far as
I can see needed.  (DEFINE_IDA does the same already).

w1: fix for loop in w1_f29_remove_slave()

2011-08-25T23:25:33+00:00

The for loop was looking for i <= 0 instead of i >= 0 so this function
never did anything.  Also we started with i = NB_SYSFS_BIN_FILES instead
of "NB_SYSFS_BIN_FILES - 1" which is an off by one bug.

w1: add Maxim/Dallas DS2780 Stand-Alone Fuel Gauge IC support

2011-05-27T00:12:38+00:00

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.

w1: add 1-wire (w1) DS2408 8-Channel Addressable Switch support

2011-05-27T00:12:38+00:00

This DS2408 w1 slave driver is not complete for all the features of the
chip, but its sufficient if you use it as a simple IO expander.

w1: DS2423 counter driver and documentation

2011-01-13T16:03:22+00:00

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

w1: w1 temp: fix negative termperature calculation

2010-04-24T18:31:25+00:00

Fix regression caused by commit 507e2fbaaacb6f164b4125b87c5002f95143174b
("w1: w1 temp calculation overflow fix") whereby negative temperatures for
the DS18B20 are not converted properly.

When the temperature exceeds 32767 milli-degrees the temperature overflows
to -32768 millidegrees.  These are both well within the -55 - +125 degree
range for the sensor.
