- PHY nodes for Aquantia devices.
- This text describes properties that are applicable to Aquantia PHY nodes in
- addition to the bindings in phy.txt.
- Aquantia PHYs allow some flexibility in the way they are wired in a system,
- they allow MDI pins to be reversed, LEDs linked up in different weays, have an
- I2C slave interface that can be used for debug. Normally the configuration
- corresponding to these is driven by the PHY firmware with the downside that
- a custom firmware is needed for each integration of a PHY.
- Several optional bindings are defined that allow these configuration points to
- be driven by the PHY driver and reduce dependency on specific FW versions.
- Optional properties:
- mdi-reversal: 0 or 1 indicating that reversal must be disabled/enabled.
- Firmware default is used if the property is missing.
- smb-addr: I2C/SMBus address to use, firmware default is used if the property
- is missing.
- Example node:
- phy@00 {
- reg = <0x00>;
- mdi-reversal = <1>;
- smb-addr = <0x25>;
- };
