mdiobus_scan: scan a bus for MDIO devices.

NAME

mdiobus_scan - scan a bus for MDIO devices.

SYNOPSIS

struct phy_device * mdiobus_scan(struct mii_bus bus, int addr);

ARGUMENTS

bus

mii_bus to scan

addr

address on bus to scan

DESCRIPTION

This function scans the MDIO bus, looking for devices which can be identified using a vendor/product ID in registers 2 and 3. Not all MDIO devices have such registers, but PHY devices typically do. Hence this function assumes anything found is a PHY, or can be treated as a PHY. Other MDIO devices, such as switches, will probably not be found during the scan.
