Update the AM65x HwSpinlock example to fix couple of warnings
that started showing up after the conversion of K3 bindings to
YAML format in commit 66e06509aa ("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.

Suman Anna d8db9dc348 dt-bindings: hwlock: omap: Convert binding to YAML
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.

Bjorn Andersson 35efb0e1d5 dt-bindings: hwlock: qcom: Remove invalid binding
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.

Bjorn Andersson d6a9f0c8f6 dt-bindings: hwlock: qcom: Allow device on mmio bus
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.

Suman Anna 0ce8cf2f31 Documentation: dt: add common bindings for hwspinlock
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.
