It's not clear to me, what has to be done to see this warning. Can you
tell me how to reproduce?

My current WIP patch is:

diff --git a/Documentation/devicetree/bindings/mtd/mxc-nand.yaml b/Documentation/devicetree/bindings/mtd/mxc-nand.yaml
index 73b86f2226c7..6e3e346e4448 100644

     maxItems: 1

which I think is right, but obviously doesn't fix the problem you
pointed out :-)

Or documented and not marked deprecated?

Best regards
