21Description
22-----------
23
24The Maxim/Dallas Semiconductor DS2482 is a I2C device that provides
25one (DS2482-100) or eight (DS2482-800) 1-wire busses.

28General Remarks
29---------------
30
31Valid addresses are 0x18, 0x19, 0x1a, and 0x1b.
32
33However, the device cannot be detected without writing to the i2c bus, so no
34detection is done. You should instantiate the device explicitly.
