* | w1: add helper macro module_w1_family | Andrew F. Davis | 2016-08-02 |
| | | | | | | | | | | | | | The helper macro module_w1_family can be used in module drivers that only register a w1 driver in their module init functions. Add this macro and use it in all applicable drivers. Link: http://lkml.kernel.org/r/20160531204313.20979-2-afd@ti.com Signed-off-by: Andrew F.

* | w1: new w1_ds2406 driver | Scott Alfter | 2014-06-19 |
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.
