mbalmer fa4785b09a Register with the PMF, and when detaching, just the right order. 2009-08-08 10:38:17 +00:00
mbalmer 61e768bf92 Don't use an identifier name that probably clashes with the C standard. 
Requested by many.

mbalmer e1a16b3665 A better match routine that checks also the number of pins instead 
of checking the pins in the attach routine; malconfigured devices will
no longer attach.  While here, replace some printf uses by aprint_....

mbalmer 8964d40bc5 Rework the GPIO framework. Tie it to the kauth(9) framework to control 
access to the GPIO pins.  Device drivers using GPIO pins can now be
attached and detached at runtime.  GPIO pins can be named for easier
reference from userland programs.  Introduce a new gpiosim(4) driver,
which is used for development.

Reviewed by many.

riz 637bfc29f9 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.
