# 1.18 17-Dec-2024 martin

Rename gpiobus.c to gpiolib.c so we can move other parts in there too.
Requested by Jared.


# 1.17 17-Dec-2024 martin

Move (the one and only) gpiobus_* function(s) into a separate file
that is build if we have gpiobus (independent of having gpio or not).

Add a 1PPS-over-GPIO driver, originally by Brad Spencer, with changes by
me to adapt to the new GPIO interrupt interface and support a wider variety
of GPIO pin configuations.

# 1.15 19-May-2018 thorpej

Add an example "gpioirq" driver that demonstrates interrupts on GPIO
pins. Will be enhanced in the future to support sending events to
user space on edge-triggered interrupt events.

Based on initial work by Brad Spencer.

gpiopwm(4) is a driver to pulse GPIO pins in software. This obsoletes
the software pulsing facilities in gpio(4) (and gpioctl(8)) which will
later be removed.

# 1.8 14-Aug-2009 mbalmer

Add support for multi-position electro-mechanical keylocks. An example
driver, gpiolock(4), is provided as an example how to interface real hardware.
A new securemodel, securemodel_keylock, is provided to show how this can
be used to tie keylocks to overall system security. This is experimental
code. The diff has been on tech-kern for several weeks.

Reviewed by many, kauth(9) integration reviewed by Elad Efrat; approved by
tonnerre@ and tron@. Thanks to everyone who provided feedback.


# 1.7 09-Aug-2009 mbalmer

gpioiic(4), a driver to do use GPIO pins in bit-banging mode to form an I2C
bus. Ported from OpenBSD.


# 1.6 27-Jul-2009 mbalmer

Do not attach gpiosim(4) at root, but make it a pseudo device.
With help from Matthias Drochner, thanks!


# 1.5 25-Jul-2009 mbalmer

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.

# 1.4 07-Apr-2006 riz

branches: 1.4.6; 1.4.64;
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.
