Function Documentation

mdio_bus_disable()

void mdio_bus_disable

(

const struct device *

dev

)

#include <include/zephyr/drivers/mdio.h>

Disable MDIO bus and tri-state drivers.

Parameters

[in]

dev

Pointer to the device structure for the controller

mdio_bus_enable()

void mdio_bus_enable

(

const struct device *

dev

)

#include <include/zephyr/drivers/mdio.h>

Enable MDIO bus.

Parameters

[in]

dev

Pointer to the device structure for the controller

mdio_read()

int mdio_read	(	const struct device *	dev,
		uint8_t	prtad,
		uint8_t	devad,
		uint16_t *	data
	)

#include <include/zephyr/drivers/mdio.h>

Read from MDIO Bus.

This routine provides a generic interface to perform a read on the MDIO bus.

Parameters

[in]	dev	Pointer to the device structure for the controller
[in]	prtad	Port address
[in]	devad	Device address
	data	Pointer to receive read data

Return values

0	If successful.
-EIO	General input / output error.
-ETIMEDOUT	If transaction timedout on the bus

mdio_write()

int mdio_write	(	const struct device *	dev,
		uint8_t	prtad,
		uint8_t	devad,
		uint16_t	data
	)

#include <include/zephyr/drivers/mdio.h>

Write to MDIO bus.

This routine provides a generic interface to perform a write on the MDIO bus.

Parameters

[in]	dev	Pointer to the device structure for the controller
[in]	prtad	Port address
[in]	devad	Device address
[in]	data	Data to write

Return values

0	If successful.
-EIO	General input / output error.
-ETIMEDOUT	If transaction timedout on the bus
