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.
The following attributes are supported.
======================= ======================================================== in0_label "AVDDL" in0_input Measured AVDDL voltage. in0_min Minimum AVDDL voltage. in0_max Maximum AVDDL voltage. in0_alarm AVDDL voltage alarm.
in1_label "AVDDH" in1_input Measured AVDDH voltage. in1_min Minimum AVDDH voltage. in1_max Maximum AVDDH voltage. in1_alarm AVDDH voltage alarm.
temp1_input Die temperature. temp1_min Minimum die temperature. temp1_max Maximum die temperature. temp1_alarm Die temperature alarm. ======================= ========================================================
