infineon,xmc4xxx-mdio

Vendor: Infineon Technologies

Description

These nodes are “mdio” bus nodes.

Infineon xmc4xxx Family MDIO Driver node

Properties

Properties not inherited from the base binding file.

Name

Type

Details

mdi-port-ctrl

string

The MDIO input is connected to several port/pins via a mux.
This is not handled by pinctrl because the mux is located at the
peripheral and not GPIO. The possible connections are defined by
an enum.

This property is required.

Legal values: 'P0_9', 'P2_0', 'P1_11'

pinctrl-0

phandles

Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.

This property is required.

pinctrl-names

string-array

Names for the provided states. The number of names needs to match the
number of states.

This property is required.

suppress-preamble

boolean

When present, the SMA suppresses the 32-bit preamble and transmits
MDIO frames with only 1 preamble bit. By default, the MDIO frame
always has 32 bits of preamble as defined in the IEEE 802.3 specs.

clock-frequency

int

Some MDIO controllers have the ability to configure the MDC frequency.
If present, this property may be used to specify the MDC frequency based
on what the PHYs connected to the mdio bus can support. Default of 2.5MHz
is the standard and should supported by all PHYs.

Default value: 2500000

pinctrl-1

phandles

Pin configuration/s for the second state. See pinctrl-0.

pinctrl-2

phandles

Pin configuration/s for the third state. See pinctrl-0.

pinctrl-3

phandles

Pin configuration/s for the fourth state. See pinctrl-0.

pinctrl-4

phandles

Pin configuration/s for the fifth state. See pinctrl-0.
