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 regards Suman > > regards > Suman > >> >> Signed-off-by: Rob Herring <robh@xxxxxxxxxx> >> --- >> .../devicetree/bindings/remoteproc/ti,k3-dsp-rproc.yaml | 2 +- >> .../devicetree/bindings/remoteproc/ti,k3-r5f-rproc.yaml | 2 +- >> 2 files changed, 2 insertions(+), 2 deletions(-) >> >> diff --git a/Documentation/devicetree/bindings/remoteproc/ti,k3-dsp-rproc.yaml b/Documentation/devicetree/bindings/remoteproc/ti,k3-dsp-rproc.yaml >> index 5ec6505ac408..648144fa1582 100644 >> --- a/Documentation/devicetree/bindings/remoteproc/ti,k3-dsp-rproc.yaml >> +++ b/Documentation/devicetree/bindings/remoteproc/ti,k3-dsp-rproc.yaml >> @@ -53,7 +53,7 @@ properties: >> OMAP Mailbox specifier denoting the sub-mailbox, to be used for >> communication with the remote processor.
