Subject: [PATCH v2 0/1] gpio-restart restart handler

This driver builds upon Guenter Roeck's kernel restart handler patchset
to add a driver which registers a GPIO-based restart handler which restarts
the system by toggling a GPIO.

Changes are based off 3.17-rc2 with the following patches from v7 of 
Guenter's patchset:
https://patchwork.kernel.org/patch/4746721/
https://patchwork.kernel.org/patch/4746731/
https://patchwork.kernel.org/patch/4747011/
https://patchwork.kernel.org/patch/4746741/
https://patchwork.kernel.org/patch/4746861/

Changes since v1:
v2:
	- Updated devicetree binding to make it less kernel specific
	- Changed priority property from u8 type to standard u32
	- Rename input property to open-source
	- Made delays configurable from binding
	- Removed unneeded BUG_ON
	- Used devm_gpiod_get flags parameter to configure initial direction
