It potentially might work if it will be possible to split > nand memory definition (or nand memory properties) out of and-controller.yaml, similarly to > ti,gpmc-child.yaml from this series. What you think would be the issue? I am not opposed to split nand-controller.yaml into nand-controller.yaml and nand-chip.yaml if it simplifies the description of controllers but I don't get why it would be needed. In particular since we expect all drivers to support the nand-controller { controller-props; nand-chip { chip-props; } } organization which has been enforced since at least 2018. Having a controller vs. chip representation is fundamentally right. But here I see how "legacy" are these bindings with so much unneeded specific "ti," properties... On one side it would be good to verify that the driver supports this representation (which I believe is true) and on the other side maybe it's time to advertise "better" bindings as well. Thanks, Miquèl
