2018-07-11power: supply: ds2760_battery: merge ds2760 supply driver with its w1 slave ↵Daniel Mack1-12/+0
companion This patch removes the w1 slave driver that used to register the w1 family and instanciate a platform device at runtime. The code now lives in the supply driver instead to avoid that level of indirection. The old device name "ds2760-battery.0" is preserved, so userspace applications can access the same virtual device nodes as before. Note that because the w1 core does not currently have a framework for suspend/resume, the driver now registers a PM notifier callback.

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. Signed-off-by: Maciej S.

2014-06-23w1: select crc16 library for ds2406Arnd Bergmann1-0/+1
commit 94859308a21b "w1: new w1_ds2406 driver" added a new driver that uses the crc16 library, but didn't ensure that the core is there. This adds the necessary Kconfig statements, just like we have it for other w1 drivers.

2014-06-19w1: new w1_ds2406 driverScott Alfter1-0/+7
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.

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.

2011-01-13w1: DS2423 counter driver and documentationMika Laitio1-0/+11
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 00 02 00 00 00 00 00 00 00 6d 38 00 ff ff 00 00 fe ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff crc=YES c=2 00 02 00 00 00 00 00 00 00 e0 1f 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff crc=YES c=2 00 5a 0e 5f 18 00 00 00 00 0b 28 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff crc=YES c=408882778 00 05 00 00 00 00 00 00 00 8d 39 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff crc=YES c=5 Patch includes also the documentation.
