The following is what you get with your current patch,

Documentation/devicetree/bindings/remoteproc/ti,k3-dsp-rproc.example.dt.yaml:
dsp@4d80800000: mboxes: [[4294967295, 4294967295]] is too short
Documentation/devicetree/bindings/remoteproc/ti,k3-dsp-rproc.example.dt.yaml:
dsp@64800000: mboxes: [[4294967295, 4294967295]] is too short
