- Broadcom BCM54140 Quad SGMII/QSGMII PHY
- =======================================
- Supported chips:
- * Broadcom BCM54140
- Datasheet: not public
- Author: Michael Walle <[email protected]>
- 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
- -------------
- The following attributes are supported.
