eth_lan865x_mdio_c22_read()

int eth_lan865x_mdio_c22_read	(	const struct device *	dev,
		uint8_t	prtad,
		uint8_t	regad,
		uint16_t *	data )

Read C22 registers using LAN865X MDIO Bus.

This routine provides an interface to perform a C22 register read on the LAN865X MDIO bus.

Parameters

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

Return values

0	If successful.
-EIO	General input / output error.
-ETIMEDOUT	If transaction timedout on the bus
-ENOSYS	if read is not supported
