Is there nvmem-1? I see binding > does it, but why? 'nvmem' is used/declared by nvmem-consumer.yaml as a phandle array already so using just 'nvmem' fails validation: Documentation/devicetree/bindings/mfd/maxim,max77759.example.dtb: pmic@66: = nvmem: {'compatible': ['maxim,max77759-nvmem'], 'nvmem- layout': {'compatible': ['fixed-layout'], '#address-cells': 1, '#size-cells= ': 1, 'reboot-mode@0': {'reg': [[0, 4]]}, 'boot-reason@4': {'reg': [[4, 4]]}, 'shutdown-user-flag@8': {'reg': [[8, 1]]}, 'rsoc@10': {'= reg': [[10, 2]]}}} is not of type 'array' from schema $id: http://devicetree.org/schemas/nvmem/nvmem-consumer.yaml# https://lore.kernel.org/all/20250226-max77759-mfd-v2-3-a65ebe2bc0a9@linaro.= org/ Cheers, Andre'
