Domap-hdq.rst2 Kernel driver for omap HDQ/1-wire module
7 HDQ/1-wire controller on the TI OMAP 2430/3430 platforms.
15 The HDQ/1-Wire module of TI OMAP2430/3430 platforms implement the hardware
17 Semiconductor 1-Wire protocols. These protocols use a single wire for
18 communication between the master (HDQ/1-Wire controller) and the slave
19 (HDQ/1-Wire external compliant device).
21 A typical application of the HDQ/1-Wire module is the communication with battery
24 The controller supports operation in both HDQ and 1-wire mode. The essential
25 difference between the HDQ and 1-wire mode is how the slave device responds to
26 initialization pulse.In HDQ mode, the firmware does not require the host to
