  14 Description
  15 -----------
  16
  17 The Broadcom BCM54140 is a Quad SGMII/QSGMII PHY which supports monitoring
  18 its die temperature as well as two analog voltages.
  19
  20 The AVDDL is a 1.0V analogue voltage, the AVDDH is a 3.3V analogue voltage.
  21 Both voltages and the temperature are measured in a round-robin fashion.
