As discussed with Krzysztof and Chris, it seems like each NAND controller binding should actually restrain the properties allowed in the NAND chip node with its own "unevaluatedProperties: false". This only works if we reference a yaml schema which contains all the possible properties *in the NAND chip node*. Indeed, the NAND controller yaml schema contains properties for the NAND chip which are not evaluated with this construction. Link: https://lore.kernel.org/all/a23dd485-a3d9-e31f-be3e-0ab293fcfc4a@xxxxxxxxxx/ While converting Marvell controller bindings, Chris explicitly pointed similar bindings which would also trigger errors when using "unevaluatedProperties: false" because of the problem mentioned above. Here is an attempt at making this logic more robust: * All NAND chip properties which are specific to the raw NAND world are moved into a raw-nand-chip.yaml file. * raw-nand-chip.yaml is referenced by all NAND controller bindings when the NAND chip must be further constrained. * raw-nand-chip.yaml and spi-nand.yaml reference nand-chip.yaml. These change made me realize the qcom,boot-partition property description was broken, and a few other descriptions needed small updates. Here is a batch of updates to fix all these.
