Hi Rob I'm slowly converting some of the Marvell binding documents to YAML. I've got a problem with one of the interrupt controllers. Documentation/devicetree/bindings/interrupt-controller/marvell,orion-intc.txt includes: Optional properties: - marvell,#interrupts: number of interrupts provided by bridge interrupt controller, defaults to 32 if not set I converted this to YAML as: 'marvell,#interrupts': description: number of interrupts provided by bridge interrupt controller $ref: /schemas/types.yaml#/definitions/uint32 default: 32 but when i run dt_binding_check, i get: home/andrew/linux/Documentation/devicetree/bindings/interrupt-controller/marvell,orion-bridge-intc.yaml: properties: 'marvell,#interrupts' does not match '^[#$a-zA-Z][a-zA-Z0-9,+\\-._@]{0,63}$' hint: Expected a valid DT property name from schema $id: http://devicetree.org/meta-schemas/keywords.yaml# As far as i can see from: https://devicetree-specification.readthedocs.io/en/v0.3/devicetree-basics.html#properties A property name is allowed a # anywhere in it, not just at the start. How do i get this regex changed? Thanks Andrew
