From d9411e57dc7fcdbf28eb825d090b06b4248a95bc Mon Sep 17 00:00:00 2001 From: Matt Campbell Date: Tue, 28 Apr 2015 07:44:17 -0400 Subject: w1: Add support for DS28EA00 sequence to w1-therm This patch provides support for the DS28EA00 digital thermometer. The DS28EA00 provides an additional two pins for implementing a sequence detection algorithm. This feature allows you to determine the physical location of the chip in the 1-wire bus without needing pre-existing knowledge of the bus ordering. Support is provided through the sysfs w1_seq file. The file will contain a single line with an integer value representing the device index in the bus starting at 0.
