The "ahb", for MAC ipg_clk, ipg_clk_mac that are bus clock.
The "ptp"(option), for IEEE1588 timer clock that requires the clock.
The "enet_clk_ref"(option), for MAC transmit/receiver reference clock like
RGMII TXC clock or RMII reference clock. It depends on board design,
the clock is required if RGMII TXC and RMII reference clock source from
SOC internal PLL.
The "enet_out"(option), output clock for external device, like supply clock
for PHY. The clock is required if PHY clock source from SOC.
The "enet_2x_txclk"(option), for RGMII sampling clock which fixed at 250Mhz.
The clock is required if SoC RGMII enable clock delay.

dt-bindings: net: Cleanup MDIO node schemas The schemas for MDIO bus nodes range from missing to duplicating everything in mdio.yaml. The MDIO bus node schemas only need to reference mdio.yaml, define any binding specific properties, and define 'unevaluatedProperties: false'. This ensures that MDIO nodes only contain defined properties. With this, any duplicated properties can be removed. Cc: "David S.

unevaluatedProperties: false
description:
Specifies the mdio bus in the FEC, used as a container for phy nodes.
# Deprecated optional properties:
# To avoid these, create a phy node according to ethernet-phy.yaml in the same
# directory, and point the FEC's "phy-handle" property to it. Then use
# the phy's reset binding, again described by ethernet-phy.yaml.
phy-reset-gpios:
deprecated: true
description:
Should specify the gpio for phy reset.
phy-reset-duration:
$ref: /schemas/types.yaml#/definitions/uint32
deprecated: true
description:
Reset duration in milliseconds. Should present only if property
"phy-reset-gpios" is available. Missing the property will have the
duration be 1 millisecond. Numbers greater than 1000 are invalid
and 1 millisecond will be used instead.
phy-reset-active-high:
type: boolean
deprecated: true
description:
If present then the reset sequence using the GPIO specified in the
"phy-reset-gpios" property is reversed (H=reset state, L=operation state).
phy-reset-post-delay:
$ref: /schemas/types.yaml#/definitions/uint32
deprecated: true
description:
Post reset delay in milliseconds. If present then a delay of phy-reset-post-delay
milliseconds will be observed after the phy-reset-gpios has been toggled.
Can be omitted thus no delay is observed. Delay is in range of 1ms to 1000ms.
Other delays are invalid.

# FIXME: We had better set additionalProperties to false to avoid invalid or at
# least undocumented properties. However, PHY may have a deprecated option to
# place PHY OF properties in the MAC node, such as Micrel PHY, and we can find
# these boards which is based on i.MX6QDL.
