I could add phys = <> as optional in the schema. Is there any reason to stop adding adjacent csiphy nodes ? isp@addr { regs = 0xCSID0, 0xCSIPH1; reg-names = "csidX", "csiphy0"; }; csiphy@CSIPHY1 {} I'm not sure if this is against DT rules. The iommu items _should_ be fine as its maxItems so I can just set that to five instead of eight in the dtsi. --- bod
