microchip,enc424j600 (on spi bus)

Vendor: Microchip Technology Inc.

Description

ENC424J600 standalone 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 ENC424J600 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.

duplex

int

 
Duplex mode, full or half. By default it's always full duplex thus 0
as this is, by far, the most common mode.
Use the macros not the actual enum value, here is the concordance
list (see dt-bindings/spi/spi.h)
  0    SPI_FULL_DUPLEX
  2048 SPI_HALF_DUPLEX

Legal values: 0, 2048

frame-format

int

 
Motorola or TI frame format. By default it's always Motorola's,
thus 0 as this is, by far, the most common format.
Use the macros not the actual enum value, here is the concordance
list (see dt-bindings/spi/spi.h)
  0     SPI_FRAME_FORMAT_MOTOROLA
  32768 SPI_FRAME_FORMAT_TI

Legal values: 0, 32768

supply-gpios

phandle-array

 
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.
