[PATCH v2 0/4] xlnx: dt-bindings: Convert to json-schema

[PATCH v2 0/4] xlnx: dt-bindings: Convert to json-schema

[Vincenzo Frascino]

This series converts the folling Xilinx device tree binding documentation:
 - xlnx,i2s
 - xlnx,audio-formatter
 - xlnx,spdif
to json-schema.

To simplify the testing a linux tree rebased on 6.13-rc4 is accessible
at [1].

Note: These bindings are required for future work on the ARM Morello
Platforms device tree.
