Field Documentation

isAlive

int32_t(* EnetPhy_Mdio::isAlive) (uint32_t phyAddr, bool *isAlive, void *arg)

Check if PHY is alive.

Checks if PHY is alive, either using an explicit register read or any other mechanism supported by the MDIO peripheral (i.e. background BMSR reads).

Parameters

phyAddr	PHY device address
isAlive	Whether PHY is alive or not
args	Caller's arguments passed to the PHY driver at open time

Returns

EnetPhy_ErrorCodes

isLinked

int32_t(* EnetPhy_Mdio::isLinked) (uint32_t phyAddr, bool *isLinked, void *arg)

Check if PHY is linked.

Checks if PHY is linked, either using an explicit register read or any other mechanism supported by the MDIO peripheral.

Parameters

phyAddr	PHY device address
isLinked	Whether PHY is linked or not
args	Caller's arguments passed to the PHY driver at open time

Returns

EnetPhy_ErrorCodes

readC22

int32_t(* EnetPhy_Mdio::readC22) (uint32_t group, uint8_t phyAddr, uint32_t reg, uint16_t *val, void *arg)

Read PHY register using Clause-22 frame.

Reads a PHY register using a Clause-22 frame.

Parameters

group	User group (use 0 if single group is supported)
phyAddr	PHY device address
reg	Register address
val	Value read from register
args	Caller's arguments passed to the PHY driver at open time

Returns

EnetPhy_ErrorCodes

writeC22

int32_t(* EnetPhy_Mdio::writeC22) (uint32_t group, uint8_t phyAddr, uint32_t reg, uint16_t val, void *arg)

Write PHY register using Clause-22 frame.

Writes a PHY register using a Clause-22 frame.

Parameters

group	User group (use 0 if single group is supported)
phyAddr	PHY device address
reg	Register address
val	Value to be written
args	Caller's arguments passed to the PHY driver at open time

Returns

EnetPhy_ErrorCodes

readC45

int32_t(* EnetPhy_Mdio::readC45) (uint32_t group, uint8_t phyAddr, uint8_t mmd, uint16_t reg, uint16_t *val, void *arg)

Read PHY register using Clause-45 frame.

Reads a PHY register using a Clause-45 frame. Returns ENETPHY_ENOTSUPPORTED if MDIO doesn't support Clause-45 frames.

Parameters

group	User group (use 0 if single group is supported)
phyAddr	PHY device address
reg	Register address
val	Value read from register
args	Caller's arguments passed to the PHY driver at open time

Returns

EnetPhy_ErrorCodes

writeC45

int32_t(* EnetPhy_Mdio::writeC45) (uint32_t group, uint8_t phyAddr, uint8_t mmd, uint16_t reg, uint16_t val, void *arg)

Write PHY register using Clause-45 frame.

Writes a PHY register using a Clause-45 frame. Returns ENETPHY_ENOTSUPPORTED if MDIO doesn't support Clause-45 frames.

Parameters

group	User group (use 0 if single group is supported)
phyAddr	PHY device address
reg	Register address
val	Value to be written
args	Caller's arguments passed to the PHY driver at open time

Returns

EnetPhy_ErrorCodes
