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/' {} \;

|
|
This binding describes the hardware component responsible for side channel
|
|
requests to the always-on subsystem (AOSS), used for certain power management
|
|
requests that is not handled by the standard RPMh interface. Each client in the
|
|
SoC has its own block of message RAM and IRQ for communication with the AOSS.
|
|
The protocol used to communicate in the message RAM is known as Qualcomm
|
|
Messaging Protocol (QMP)
|
|
|
|
The AOSS side channel exposes control over a set of resources, used to control
|
|
a set of debug related clocks and to affect the low power state of resources
|
|
related to the secondary subsystems.

The AOSS side channel also provides the controls for three cooling devices,
|

these are expressed as subnodes of the QMP node. The name of the node is
|
|
used to identify the resource and must therefor be "cx", "mx" or "ebi".
