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/' {} \;

In older device trees this can be the accidental name for the analog
|
|
supply on the VCCA pin, and in that case the deprecated vddo-supply is
|
|
used for the digital power supply.
|
|
|
|
vddo-supply:
|
|
description: Deprecated name for the digital power supply, use vdd-supply
|
|
as this reflects the real name of the pin. If this supply is present,
|
|
the vdd-supply represents VCCA instead of VDD. Implementers should first
|
|
check for this property, and if it is present assume that the vdd-supply
|
|
represents the analog supply.
