Vendor: Atmel Corporation

Note

An implementation of a driver matching this compatible is available in drivers/ethernet/eth_sam_gmac.c.

Description

Atmel SAM0-family GMAC Ethernet

Properties

Properties not inherited from the base binding file.

Name

Type

Details

phy-handle

phandle

 
Specifies a reference to a node representing a PHY device.

This property is required.

num-queues

int

 
Number of hardware TX and RX queues.

This property is required.

max-frame-size

int

 
Maximum ethernet frame size.  The current ethernet frame sizes
supported by hardware are 1518, 1536 and 10240 (jumbo frames).  This
means that normally gmac will reject any frame above max-frame-size
value.  The default value is 1518, which represents an usual
IEEE 802.3 ethernet frame:

  Ethernet Frame [ 14 MAC HEADER | 1500 MTU | 4 FCS ] = 1518 bytes

When using value 1536 it is possible extend ethernet MAC HEADER up
to 32 bytes.  The hardware have support to jumbo frames and it can be
enabled by selecting the value 10240.

Default value: 1518

max-speed

int

 
This specifies maximum speed in Mbit/s supported by the device.  The
gmac driver supports 10Mbit/s and 100Mbit/s.  Using 100, as default
value, enables driver to configure 10 and 100Mbit/s speeds.

Default value: 100

mac-eeprom

phandle

 
phandle to I2C eeprom device node.

phy-connection-type

string

 
Specifies the interface connection type between ethernet MAC and PHY.

Default value: rmii

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

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.

pinctrl-0

phandles

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

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.

pinctrl-names

string-array

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