That's not true, there is, just it's not converted to dt-schema:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/leds/leds-pca955x.txt?h=v6.11

So the nodes can stay, though they probably generate warnings. The
right way to fix this is to convert the binding document.

Hi Andrew,
Thanks for your suggestions.
I'll remain the nodes and provide the binding document in another patch.

This isn't changing the address, it's fixing the compatible string.
Please make this a separate patch with an appropriate Fixes: tag.

Maybe put this in the same patch as the compatible fix though, if it's
correct.
