Function Documentation

no_os_mdio_init()

int no_os_mdio_init	(	struct no_os_mdio_desc **	desc,
		const struct no_os_mdio_init_param *	param )

Initialize the MDIO interface.

Parameters

desc	- The MDIO descriptor.
param	- MDIO parameters.

Returns

0 in case of success, error code otherwise.

no_os_mdio_read()

int no_os_mdio_read	(	struct no_os_mdio_desc *	desc,
		uint32_t	reg,
		uint16_t *	val )

Read a register using MDIO.

Parameters

desc	- The MDIO descriptor.
reg	- Register address. For clause 45 reg is constructed using NO_OS_MDIO_C45_ADDR macro. It is otherwise the plain clause 22 address (0...31).
val	- Value read from register.

Returns

0 in case of success, error code otherwise.

no_os_mdio_remove()

int no_os_mdio_remove

(

struct no_os_mdio_desc *

desc

)

Free the resources allocated by no_os_mdio_init().

Parameters

desc	- The MDIO descriptor.

Returns

0 in case of success, error code otherwise.

no_os_mdio_write()

int no_os_mdio_write	(	struct no_os_mdio_desc *	desc,
		uint32_t	reg,
		uint16_t	val )

Write a register using MDIO.

Parameters

desc	- The MDIO descriptor.
reg	- Register address. For clause 45 reg is constructed using NO_OS_MDIO_C45_ADDR macro. It is otherwise the plain clause 22 address (0...31).
val	- Value to write into register.

Returns

0 in case of success, error code otherwise.
