The Devicetree bindings document does not have to say in the title that
it is a "binding", but instead just describe the hardware.
Drop trailing "bindings" in various forms (also with trailing full
stop):
find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
-not -name 'trivial-devices.yaml' \
-exec sed -i -e 's/^title: \(.*\) [bB]indings\?\.\?$/title: \1/' {} \;

title: ST Microelectronics Nomadik I2C
|
|
|
|
description: The Nomadik I2C host controller began its life in the ST
|
|
Microelectronics STn8800 SoC, and was then inherited into STn8810 and
|
|
STn8815. It was part of the prototype STn8500 which then became ST-Ericsson
|
|
DB8500 after the merge of these two companies wireless divisions.
