branches: 1.1.2; 1.1.4; 1.1.6; 1.1.10; 1.1.14; 1.1.20; Dallas Semiconductor 1-Wire bus support, from OpenBSD. Currently includes gpioow(4), attaching a bit-banging driver via a GPIO pin. Also, owtemp(4) which supports some of the 1-Wire temperature sensors, including the DS18b20 and DS1920 - temperatures are returned via the envsys(4) framework.
Original drivers by Alexander Yurchenko (grange@openbsd), with envsys(4) support and a fix to the 1-wire search algorithm (for discovering devices on the bus) by me.
As discussed on tech-kern earlier this week.
