The Realtek system controllers are already in use with only generic
'"syscon", "simple-mfd"' compatibles and are missing specific
compatibles as required. Add a schema with specific compatibles. The
labels used in .dts files serve as the basis for the names.
It's doubtful the child nodes upstream are complete and I don't have
documentation, so the specific child nodes aren't documented here. Of
the ones in use, bindings already exist for them.

Current binding document enforces presence of either port@0 (DSI in) or
port@1 (DPI IN/OUT), with port@2 (DP out) being optional. This bridge is
capable of DSI->DP, DPI->DP and DPI->DP, it is therefore perfectly valid
to have both port@0 and port@1 described in the DT, because this is fairy
standard DPI->DP configuration of this bridge. Replace oneOf with anyOf
to cover this configuration.

This function first duplicates p1 and p2 into new, and then checks whether
the duplication succeeds. However, if the duplication fails (e.g.,
kzalloc() returns NULL in __of_prop_dup()), new will be NULL but is still
dereferenced in __of_prop_free(). To ensure that the unit test continues to
run even when duplication fails, add a NULL check before calling
__of_prop_free().

Updates the Device Tree bindings for Xilinx firmware by introducing
conditional schema references for the pinctrl node.
Previously, the pinctrl node directly referenced
xlnx,zynqmp-pinctrl.yaml. However, this patch modifies the schema to
conditionally apply the correct pinctrl schema based on the compatible
property. Specifically:
- If compatible contains "xlnx,zynqmp-pinctrl", reference
xlnx,zynqmp-pinctrl.yaml.
- If compatible contains "xlnx,versal-pinctrl", reference
xlnx,versal-pinctrl.yaml.
Additionally, an example entry for "xlnx,versal-pinctrl" has been
added under the examples section.

Running the full 'make dt_binding_check' is slow. A shortcut is to set
DT_SCHEMA_FILES env variable to a substring of DT schema files to test.
It both limits which examples are validated and which schemas are used
to validate the examples. This is a problem because errors from other
schemas are missed. What makes validation slow is checking all examples,
so we really just need a way to test a single example.
Add a %.yaml target to validate the schema and validate the example:
make example-schema.yaml
The behavior for 'make dt_binding_check DT_SCHEMA_FILES=example-schema'
is unchanged. Really it should mirror dtbs_check and validate all the
examples with a subset of schemas, but there are lots of users of
expecting the existing behavior.
