Name

get_phy_id — reads the specified addr for its ID.

Synopsis

int get_phy_id (struct mii_bus * bus,
 int addr,
 u32 * phy_id,
 bool is_c45,
 struct phy_c45_device_ids * c45_ids);
 

Arguments

struct mii_bus * bus

the target MII bus

int addr

PHY address on the MII bus

u32 * phy_id

where to store the ID retrieved.

bool is_c45

If true the PHY uses the 802.3 clause 45 protocol

struct phy_c45_device_ids * c45_ids

where to store the c45 ID information.

Description

In the case of a 802.3-c22 PHY, reads the ID registers of the PHY at addr on the bus, stores it in phy_id and returns zero on success.

In the case of a 802.3-c45 PHY, get_phy_c45_ids is invoked, and its return value is in turn returned.
