It looks like a downstream property resurfacing. We expect one DT subnode per chip, so I don't see the need for num-cs, we just need to count the children nodes. For me, the correct fix is to drop num-cs from the upstream DT. The only real use for it would be if the hardware could be synthesized differently, with a single CS instead of 2, but I don't think it's the case here. > + > + power-domains: > + maxItems: 1 This one, even though we don't actively use it in Linux, it may serve a real purpose.
