This patch changes the devicetree bindings for the pps-gpio driver from the integer based API to the descriptor based API. It also adds documentation for the device tree capture-clear option.
The change from integer based GPIO API to the descriptor based API breaks backward compatibility for the devicetree. This is due to the descriptor based API appending "-gpio" or "-gpios" (see Documentation/gpio/base.txt.)
