Documentation/process/license-rules.rst and checkpatch expect the SPDX
identifier syntax for multiple licenses to use capital "OR". Correct it
to keep consistent format and avoid copy-paste issues.
Correct also the format // -> .* in few Allwinner binding headers as
pointed out by checkpatch:

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/' {} \;

The TCSR_MUTEX region contains two set of registers: mutex and halt.
Add syscon, so the TCSR mutex device (hwspinlock) can use MMIO based
method and in the same time share regmap with other devices for the halt
regs.

Older Qualcomm SoCs have TCSR mutex registers with 0x80 stride, instead
of 0x1000. Add dedicated compatibles for such case. Unfortunately the
binding started using a generic "qcom,tcsr-mutex" compatible without
specifying the SoC part, thus it looks now quite inconsistent.

The example includes a board-specific compatible property, this is wrong
as the example should be board agnostic and should represent the particular
binding. Also, the file includes two similar examples but with a different
compatible. So, drop the entire second example

that started showing up after the conversion of K3 bindings to
YAML format in commit 66e06509aa37 ("dt-bindings: arm: ti:
Convert K3 board/soc bindings to DT schema").
compatible: ['ti,am654'] is not valid under any of the given schemas (Possible causes of the failure):
compatible: ['ti,am654'] is too short
compatible:0: 'ti,am654' is not one of ['ti,am654-evm']
Also, fix one of the node names while at this.

Convert the current OMAP hwspinlock binding from text format to YAML
format/DT schema, and delete the legacy text binding file.
The new YAML binding conversion is a slightly updated version compared
to the original. The legacy "ti,hwmods" property is now obsolete and
is dropped altogether, and the K3 example is updated to showcase the
actual dts node usage.

The Qualcomm hwlock is described in DeviceTree either directly on the
mmio bus or split between a syscon and a mutex node, but as noted in
[1] the latter is not valid DT, so remove any traces of this from the
binding.

In modern Qualcomm platforms the mutex region of the TCSR is forked off
into its own block, all with a offset of 0 and stride of 4096, and in
some of these platforms no other registers in this region is accessed
from Linux.
Update the binding to allow the hardware block to be described directly
on the mmio bus, in addition to allowing the existing syscon based
definition for backwards compatibility.

This patch adds the generic common bindings used to represent
a hwlock device and use/request locks in a device-tree build.
Each hwspinlock provider should have the '#hwlock-cells' property,
which represents the number of cells to be used for representing
a specific hwspinlock. Client users shall use the property
'hwlocks' for requesting specific lock(s).
Note that the document is named hwlock.txt deliberately to keep
it a bit more generic.
