Vendor: STMicroelectronics

Description

ST STM32H7 Ethernet

This binding file describes the device tree properties required to configure
and use the Ethernet controller on STM32H7 and STM32H5 series microcontrollers.
The `st,stm32h7-ethernet` compatible string can be used for both series,
ensuring flexibility and ease of configuration.

Properties

Properties not inherited from the base binding file.

Name

Type

Details

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.

local-mac-address

uint8-array

Specifies the MAC address that was assigned to the network device

zephyr,random-mac-address

boolean

Use a random MAC address generated when the driver is initialized.
Note that using this choice and rebooting a board may leave stale
MAC address in peers' ARP caches and lead to issues and delays in
communication.  (Use "ip neigh flush all" on Linux peers to clear
ARP cache.)

It is driver specific how the OUI octets are handled.

If set we ignore any setting of the local-mac-address property.

phy-handle

phandle

Specifies a reference to a node representing a PHY device.

phy-connection-type

string

Specifies the interface connection type between ethernet MAC and PHY.

Legal values: 'mii', 'rmii', 'gmii', 'rgmii'

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.
