-Subject: [PATCH 060/170] enabling the realtime clock 1-wire chip DS1307 and
- 1-wire on GPIO4 (as a module)
-
-1-wire: Add support for configuring pin for w1-gpio kernel module
-See: https://github.com/raspberrypi/linux/pull/457
-
-Add bitbanging pullups, use them for w1-gpio
-
-Allows parasite power to work, uses module option pullup=1
-
-bcm2708: Ensure 1-wire pullup is disabled by default, and expose as module parameter
-
-Signed-off-by: Alex J Lennon <ajlennon@dynamicdevices.co.uk>
-
-w1-gpio: Add gpiopin module parameter and correctly free up gpio pull-up pin, if set
-
-Signed-off-by: Alex J Lennon <ajlennon@dynamicdevices.co.uk>
-
-w1-gpio: Sort out the pullup/parasitic power tangle
