+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.
+
+Sysfs entries
