 1.2  30-Nov-2019  ad onewire:

- Re-do the signalling to be a little more forgiving and efficient.
- If bus reset fails during probe, try a second time.
- Spread out kernel threads for many busses to avoid thundering herd effect.
 1.1  07-Apr-2006  riz branches: 1.1.2; 1.1.4; 1.1.6; 1.1.10; 1.1.14; 1.1.20; 1.1.164;
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.
