Checkpatch tells me:
WARNING: DT compatible string "ti,omap4-panda-a4" appears un-documented
So I think Documentation/devicetree/bindings/arm/ti/omap.yaml needs an
update too. (and note the binding update should be a separate patch[1])

If keeping it is just this binding update, then I'd say we keep it, but
if it gets any more paninful to maintain, I'm also not going to argue
very hard to keep it.

1) The Documentation/ and include/dt-bindings/ portion of the patch should
be a separate patch. The preferred subject prefix for binding patches is::
