Description
Atmel SAM0-family GMAC Ethernet
Properties
Properties not inherited from the base binding file.

|---|---|---|
|
|
Specifies the MAC address that was assigned to the network device
|
|
|
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.
|
|
|
Specifies a reference to a node representing a PHY device.
This property is required. |
|
|
Specifies the interface connection type between ethernet MAC and PHY.
Default value: Legal values: |
|
|
Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.
|
|
|
Pin configuration/s for the second state. See pinctrl-0.
|
|
|
Pin configuration/s for the third state. See pinctrl-0.
|
|
|
Pin configuration/s for the fourth state. See pinctrl-0.
|
|
|
Pin configuration/s for the fifth state. See pinctrl-0.
|
|
|
Names for the provided states. The number of names needs to match the
number of states.
|
|
|
Number of hardware TX and RX queues.
This property is required. |
|
|
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: |
|
|
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: |
|
|
phandle to I2C eeprom device node.
|
Deprecated properties not inherited from the base binding file.
(None)
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 “atmel,sam0-gmac” compatible.

|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
|
|
|
List of power states that will disable this device power.
|
|
|
indicates the operational status of a device

This property is required. See Important properties for more information. |
|
|
name of each register space
|
|
|
interrupts for device
See Important properties for more information. |
|
|
extended interrupt specifier for device
|
|
|
name of each interrupt
|
|
|
phandle to interrupt controller node
|
|
|
Human readable string describing the device (used as device_get_binding() argument)
See Important properties for more information. This property is deprecated. |

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
