2011-10-03	Add a 'flag' locator to gpioiic(4), and define a first flag	Matthieu Herrb
	value to swap the SDA and SCL pins assigment during attach. Mostly from work with mbalmer@NetBSD. ok miod@
2008-11-24	- Add two new ioctls to gpio(4), GPIOATTACH and GPIODETACH, to allow to attach	Marc Balmer
	and detach devices on a gpiobus at runtime. The offset and mask locators in kernel config files can still be used for static configuration, so this does not break existing custome kernel configs. - Have gpioow(4) unmap the pins it used from the gpiobus during detach Changes to gpioctl(8) will be a separate committ. ok uwe
2007-06-05	Switch to rwlock(9)	Jonathan Gray

2006-01-20	Add support for driving SDA in push-pull + tri-state mode.	Alexander Yurchenko

2006-01-18	Check that SDA pin is able to read input.	Alexander Yurchenko

2006-01-17	Make it detachable.	Alexander Yurchenko

2006-01-15	Nit.	Alexander Yurchenko

2006-01-14	Some improvements:	Alexander Yurchenko
	- use gpio_pin_caps() while configuring pins - try to deal not only with open-drain outputs
2006-01-14	Support for I2C bus bit-banging through the GPIO pins.	Alexander Yurchenko
