Are you sure it's not a larger device starting at 0x1800c000 or 0x18000000? Also, please provide a more specific compatible string based on the name of the device in the data sheet. The node name in contrast should be more generic, e.g. cru: system-controller@1800c000 { compatible = "brcm,bcm53010-cru", "syscon"; reg = <0x1800c000 0x400>; /* whatever the data sheet says */ }; Arnd -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
