The Devicetree bindings document does not have to say in the title that
it is a "Devicetree binding", but instead just describe the hardware.
Drop beginning "Devicetree bindings" in various forms:
find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
-exec sed -i -e 's/^title: [dD]evice[ -]\?[tT]ree [bB]indings\? for \([tT]he \)\?\(.*\)$/title: \u\2/' {} \;
find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
-exec sed -i -e 's/^title: [bB]indings\? for \([tT]he \)\?\(.*\)$/title: \u\2/' {} \;

-exec sed -i -e 's/^title: [dD][tT] [bB]indings\? for \([tT]he \)\?\(.*\)$/title: \u\2/' {} \;

As indicated in
link: https://lore.kernel.org/all/[email protected]/
DT schema files should not have 'Device Tree Binding' as part of there
title: line. Remove this in most .yaml files, so hopefully preventing
developers copying it into new .yaml files, and being asked to remove
it.

The PS/2 bus defines data and clock line to be open drain, this should
be reflected in the gpio flags set in the binding.
Especially, this is important since the clock line sometimes is driven
by the host while being used as interrupt source.

The Arm PL050 "Keyboard/Mouse Interface" is an Arm system IP providing a
PS/2 compatible serial interface.
Add a simple DT schema binding, based on the TRM[1], the existing DTs and
the Linux driver.

The older Allwinner SoCs have a PS2 controller that is supported in Linux,
with a matching Device Tree binding.
Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

Turns out this is not such a great idea. Once the SP clock is disabled,
it's not sufficient to just enable in order to bring the SP core back up.
It seems that the kernel has no business managing this clock. Just let
the firmware keep it enabled.
This reverts commit ed22cee91a88c47e564478b012fdbcb079653499.

Improve the binding example by removing all the leading 0x to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"

Pull DeviceTree updates from Rob Herring:
"There's a few orphans in the conversion to %pOF printf specifiers
included here that no one else picked up.
Summary:
- Convert more DT code to use of_property_read_* API.
- Improve DT overlay support when adding multiple overlays
- Convert printk's to %pOF format specifiers. Most went via subsystem
trees, but picked up the remaining orphans
- Correct unittests to use preferred "okay" for "status" property
value
- Add a KASLR seed property
- Vendor prefixes for Mellanox, Theobroma System, Adaptrum, Moxa
- Fix modalias buffer handling
- Clean-up of include paths for building dtbs
- Add bindings for amc6821, isl1208, tsl2x7x, srf02, and srf10
devices
- Add nvmem bindings for MediaTek MT7623 and MT7622 SoC
- Add compatible string for Allwinner H5 Mali-450 GPU
- Fix links to old OpenFirmware docs with new mirror on
devicetree.org
- Remove status property from binding doc examples"

Pretty much any node can have a status property, so it doesn't need to
be in examples.
Converted with the following command and removed examples with SoC and
board specific splits:

This driver provides PS/2 serio bus support by implementing bit banging
with the GPIO API. The GPIO pins, data and clock, can be configured with
a node in the device tree or by generic device properties (GDP).
Writing to a device is supported as well, though it is possible timings
can not be halt as they are tough and difficult to reach with bit banging.
Therefore it can be configured (also in DT and GDP) whether the serio
write function should be available for clients.
This driver is for development purposes and not recommended for productive
use. However, this driver can be useful e.g. when no USB port is available
or using old peripherals is desired as PS/2 controller chips getting rare.
This driver was tested on bcm2825 and on Kirin 960 and it worked well
together with the atkbd and psmouse driver.

The OLPC XO-1.75 and XO-4 laptops include a PS/2 touchpad and an AT
keyboard, yet they do not have a hardware PS/2 controller. Instead, a
firmware runs on a dedicated core ("Security Processor", part of the SoC)
that acts as a PS/2 controller through bit-banging.
Communication between the main cpu (Application Processor) and the
Security Processor happens via a standard command mechanism implemented
by the SoC. Add a driver for this interface to enable keyboard/mouse
input on this platform.
