This patch implements the PPS ECHO functionality for pps-gpio, that
sysfs claims is available already.
Configuration is done via device tree bindings.
No changes are made to userspace interfaces.
This patch was originally written by Lukas Senger as part of a masters
thesis project and modified for inclusion into the linux kernel by Tom
Burkart.

This patch changes the GPIO access for the pps-gpio driver from the
integer based API to the descriptor based API.
The integer based API is considered deprecated and the descriptor based
API is the preferred way to access GPIOs as per
Documentation/driver-api/gpio/intro.rst
No changes are made to userspace interfaces.

Collection of aesthetic adjustments to various PPS-related files,
directories and Documentation, some quite minor just for the sake of
consistency, including:
* Updated example of pps device tree node (courtesy Rodolfo G.)
* "PPS-API" -> "PPS API"
* "pps_source_info_s" -> "pps_source_info"
* "ktimer driver" -> "pps-ktimer driver"
* "ppstest /dev/pps0" -> "ppstest /dev/pps1" to match example
* Add missing PPS-related entries to MAINTAINERS file
* Other trivialities

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.
