SubjectRe: [PATCH v3 2/2] of_mdio: Allow the DT to specify the phy ID and avoid autoprobing
From: Jason Gunthorpe <>
Date: Wed, 19 Mar 2014 16:15:24 -0600

> This makes the generic of_mdiobus_register parse the DT compatible string for
> the pattern ethernet-phy-idAAAA.BBBB. If present it should be a value that
> matches the phy-id register normally readable through MDIO.
> When the ID is given the phy autoprobing is defeated and the phy is
> created directly.
> This is necessary to support phy's that cannot be autoprobed when
> of_mdiobus_register is called. Specifically, my case has the phy in reset at
> of_mdiobus_register, the reset is only released once the ethernet driver
> starts, before it attaches to the phy.
> Tested on ARM Kirkwood with phy id 0x01410e90 (Marvell 88E1318)
> Signed-off-by: Jason Gunthorpe <>
> Acked-by: Florian Fainelli <>

Also applied to net-next.
