[PATCH 0/5] Add PPS pulse-width support

[Eliav Farber]

This series of five patches adds pulse-width calculation support to the
pps core (patch 1)
It then enables pulse-width calculation for the pps-gpio driver (patches
2 - 5).

*) Pulse-width in measured in nano seconds.
*) Width time can be calculated for both assert-time and reset-time.
*) New sysfs were added to expose the pulse-width.
*) Support was added to pps-gpio driver to enable capture-clear based on
   device-tree. 
*) Enabling pulse-width calculation for pps-gpio driver is done based on
   new boolean device-tree properties.

Eliav Farber (5):
  pps: add pulse-width calculation in nsec
  dt-bindings: pps: pps-gpio: introduce capture-clear property
  pps: clients: gpio: add option to set capture-clear from device-tree
  dt-bindings: pps: pps-gpio: introduce pulse-width properties
  pps: clients: gpio: enable pps pulse-width calculations based on
    device-tree
