Description
-----------

The Maxim/Dallas Semiconductor DS2482 is a I2C device that provides
one (DS2482-100) or eight (DS2482-800) 1-wire buses.


General Remarks
---------------

Valid addresses are 0x18, 0x19, 0x1a, and 0x1b.

However, the device cannot be detected without writing to the i2c bus, so no
detection is done. You should instantiate the device explicitly.

::

  $ modprobe ds2482
  $ echo ds2482 0x18 > /sys/bus/i2c/devices/i2c-0/new_device

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
