See fixed-link.txt in the same directory. - Use instead of phy-handle. -- fsl,num-tx-queues : The property is valid for enet-avb IP, which supports - hw multi queues. Should specify the tx queue number, otherwise set tx queue - number to 1. -- fsl,num-rx-queues : The property is valid for enet-avb IP, which supports - hw multi queues. Should specify the rx queue number, otherwise set rx queue - number to 1. -- fsl,magic-packet : If present, indicates that the hardware supports waking - up via magic packet. -- fsl,err006687-workaround-present: If present indicates that the system has - the hardware workaround for ERR006687 applied and does not need a software - workaround. -- fsl,stop-mode: register bits of stop mode control, the format is - <&gpr req_gpr req_bit>. - gpr is the phandle to general purpose register node. - req_gpr is the gpr register offset for ENET stop request. - req_bit is the gpr bit offset for ENET stop request. - -interrupt-names: names of the interrupts listed in interrupts property in - the same order. The defaults if not specified are - __Number of interrupts__ __Default__ - 1 "int0" - 2 "int0", "pps" - 3 "int0", "int1", "int2" - 4 "int0", "int1", "int2", "pps" - The order may be changed as long as they correspond to the interrupts - property. Currently, only i.mx7 uses "int1" and "int2". They correspond to - tx/rx queues 1 and 2. "int0" will be used for queue 0 and ENET_MII interrupts. - For imx6sx, "int0" handles all 3 queues and ENET_MII. "pps" is for the pulse - per second interrupt associated with 1588 precision time protocol(PTP). - -Optional subnodes: -- mdio : specifies the mdio bus in the FEC, used as a container for phy nodes - according to phy.txt in the same directory - -Deprecated optional properties: - To avoid these, create a phy node according to phy.txt in the same - directory, and point the fec's "phy-handle" property to it. Then use - the phy's reset binding, again described by phy.txt. -- phy-reset-gpios : Should specify the gpio for phy reset -- phy-reset-duration : 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 : 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 : 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.
