pps: new client driver using GPIO
This client driver allows you to use a GPIO pin as a source for PPS signals. Platform data [1] are used to specify the GPIO pin number, label, assert event edge type, and whether clear events are captured. This driver is based on the work by Ricardo Martins who submitted an initial implementation [2] of a PPS IRQ client driver to the linuxpps mailing-list on Dec 3 2010.
