Vendor: Synopsys, Inc.
Description
These nodes are “mdio” bus nodes.
Synopsys DWC XGMAC MDIO SMA Driver node
Properties
Properties not inherited from the base binding file.

Details |
|---|---|---|
|
|
When present, the SMA suppresses the 32-bit preamble and transmits
MDIO frames with only 1 preamble bit. By default, the MDIO frame
always has 32 bits of preamble as defined in the IEEE 802.3 specs.
|
|
|
Some MDIO controllers have the ability to configure the MDC frequency.
If present, this property may be used to specify the MDC frequency based
on what the PHYs connected to the mdio bus can support. Default of 2.5MHz
is the standard and should supported by all PHYs.
Default value: |
|
|
MDIO csr reference clock speed
- 0: "100_150MHZ"
- 1: "150_250MHZ"
- 2: "250_300MHZ"
- 3: "300_350MHZ"
- 4: "350_400MHZ"
- 5: "450_500MHZ"
Default value: |
|
|
When this field is true, it overrides the default
MDIO clock generation based on CSR clock.
|
|
|
get reset line value

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 “snps,dwcxgmac-mdio” 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
