2 Introduction to the 1-wire (w1) subsystem
5 The 1-wire bus is a simple master-slave bus that communicates via a single
6 signal wire (plus ground, so two wires).
8 Devices communicate on the bus by pulling the signal to ground via an open
14 All w1 slave devices must be connected to a w1 bus master device.
18     - DS9490 usb device
19     - W1-over-GPIO
20     - DS2482 (i2c to w1 bridge)
21     - Emulated devices, such as a RS232 converter, parallel port adapter, etc
25 ------------------------------
29  - sysfs entries for that w1 master are created
30  - the w1 bus is periodically searched for new slave devices
36 in nature, which can contain several (two or one) low-level operations.
50 ------------------
60   - (ds18?20 thermal sensor family driver)
61     provides temperature reading function which is bound to ->rbin() method
65   - driver for simple 64bit memory cell provides ID reading method.
71 -----------------------------------------------
78 Devices that support the 1-wire natively must provide the ability to write and
81 Most hardware provides higher-level functions that offload w1 handling.
