adin2111_mdio_c45_read()

int adin2111_mdio_c45_read	(	const struct device *	dev,
		uint8_t	prtad,
		uint8_t	devad,
		uint16_t	regad,
		uint16_t *	data
	)

Read from MDIO Bus using Clause 45 access.

Note

The caller is responsible for device lock. Shall not be called from ISR.

Parameters

[in]	dev	MDIO device.
[in]	prtad	Port address.
[in]	devad	Device address.
[in]	regad	Register address.
[out]	data	Pointer to receive read data.

Return values

0	If successful.
-EIO	General input / output error.
-ETIMEDOUT	If transaction timedout on the bus.
<0	Error, a negative errno code.
