Refer to the device binding for details on what disabled means for a given device. "fail" Indicates that the device is not operational.

A serious error was detected in the device and it is unlikely to become operational without repair. The sss portion of the value is specific to the device and indicates the error condition detected. -- 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
