The patch titled
Subject: dt-bindings: pps: pps-gpio PPS ECHO implementation
has been removed from the -mm tree. Its filename was
dt-bindings-pps-pps-gpio-pps-echo-implementation.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Tom Burkart <tom@xxxxxxxxxx>
Subject: dt-bindings: pps: pps-gpio PPS ECHO implementation
This patch implements the device tree binding changes required for the PPS
ECHO functionality for pps-gpio, that sysfs claims is available already.
It adds two DT properties for configuring the PPS ECHO functionality.
This patch is provided separated from the rest of the patch per
Documentation/devicetree/bindings/submitting-patches.txt.
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.
