Broadcom BCM54140 Quad SGMII/QSGMII PHY
=======================================
Supported chips:
* Broadcom BCM54140
Datasheet: not public
Author: Michael Walle <michael@walle.cc>
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.
