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