- *
- * During interrupt and other critical calls, a spinlock is used to

- * access to the device.
- *
- * For general accesses a lock is provided so that calls which are

- * not need to be saved. This lock also serves to serialise access
- * to the EEPROM and PHY access registers which are shared between
