Function Documentation

int axienet_mdio_setup	(	struct axienet_local *	lp,
		struct device_node *	np
	)

axienet_mdio_setup - MDIO setup function : Pointer to axienet local data structure. : Pointer to device node

returns: 0 on success, -ETIMEDOUT on a timeout, -ENOMEM when mdiobus_alloc (to allocate memory for mii bus structure) fails.

Sets up the MDIO interface by initializing the MDIO clock and enabling the MDIO interface in hardware. Register the MDIO interface.
