  8. Description
  9. -----------
  10. The Broadcom BCM54140 is a Quad SGMII/QSGMII PHY which supports monitoring
  11. its die temperature as well as two analog voltages.
  12. The AVDDL is a 1.0V analogue voltage, the AVDDH is a 3.3V analogue voltage.
  13. Both voltages and the temperature are measured in a round-robin fashion.
  14. Sysfs entries
