7 title: UART 1-Wire Bus
10   - Christoph Winklhofer <cj.winklhofer@gmail.com>
13   UART 1-wire bus. Utilizes the UART interface via the Serial Device Bus
14   to create the 1-Wire timing patterns.
16   The UART peripheral must support full-duplex and operate in open-drain
18   baud-rate and transmitted byte, which corresponds to a 1-Wire read bit,
21   The default baud-rate for reset and presence detection is 9600 and for
22   a 1-Wire read or write operation 115200. In case the actual baud-rate
24   to generate the 1-Wire timing patterns.

32   reset-bps:
35       The baud rate for the 1-Wire reset and presence detect.
37   write-0-bps:
40       The baud rate for the 1-Wire write-0 cycle.
42   write-1-bps:
45       The baud rate for the 1-Wire write-1 and read cycle.
