0014 Description
0015 -----------
0016
0017 The Broadcom BCM54140 is a Quad SGMII/QSGMII PHY which supports monitoring
0018 its die temperature as well as two analog voltages.
0019
0020 The AVDDL is a 1.0V analogue voltage, the AVDDH is a 3.3V analogue voltage.
0021 Both voltages and the temperature are measured in a round-robin fashion.
