wiznet,w5500 (on spi bus)

Vendor: Unknown vendor

Description

W5500 standalone 10/100BASE-T Ethernet controller with SPI interface

Properties

Properties not inherited from the base binding file.

Name

Type

Details

int-gpios

phandle-array

Interrupt pin.
The interrupt pin of W5500 is active low. If connected directly the MCU pin should be configured as active low.

This property is required.

reset-gpios

phandle-array

Reset pin.
The reset pin of W5500 is active low. If connected directly the MCU pin should be configured as active low.

This property is required.

spi-max-frequency

int

Maximum clock frequency of device's SPI interface in Hz

This property is required.

supply-gpios

phandle

GPIO specifier that controls power to the device.

This property should be provided when the device has a dedicated
switch that controls power to the device.  The supply state is
entirely the responsibility of the device driver.

Contrast with vin-supply.

vin-supply

phandle

Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.

This property should be provided when device power is supplied
by a shared regulator.  The supply state is dependent on the
request status of all devices fed by the regulator.

Contrast with supply-gpios.  If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.

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.

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “wiznet,w5500” compatible.
