2 Introduction to the 1-wire (w1) subsystem
11 The w1 subsystem provides the framework for managing w1 masters and
14 All w1 slave devices must be connected to a w1 bus master device.
16 Example w1 master devices:
20 - DS2482 (i2c to w1 bridge)
24 What does the w1 subsystem do?
27 When a w1 master driver registers with the w1 subsystem, the following occurs:
29 - sysfs entries for that w1 master are created
30 - the w1 bus is periodically searched for new slave devices
32 When a device is found on the bus, w1 core tries to load the driver for its family
44 It is possible that between 1. and 2. w1 master thread will reset bus for searching
52 Slave devices are handled by a driver written for a family of w1 devices.
55 registers with the w1 subsystem.
70 What does a w1 master driver need to implement?
73 The driver for w1 bus master must provide at minimum two functions.
81 Most hardware provides higher-level functions that offload w1 handling.
82 See struct w1_bus_master definition in w1.h for details.
85 w1 master sysfs interface
91 bus (standard) symlink to the w1 bus
92 driver (standard) symlink to the w1 driver
107 If you have a w1 bus that never changes (you don't add or remove devices),
122 w1 slave sysfs interface
126 bus (standard) symlink to the w1 bus
127 driver (standard) symlink to the w1 driver
