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
