Syscon can also have child nodes that share a registration file with it. To do this correctly, follow these steps: - subclass syscon from simplebus and expose it if the node is also "simple-bus" compatible. - block simplebus probe for this compatible string, so it's priority (bus pass) doesn't colide with syscon driver.
