Subject: [PATCHv3 0/4] Add DT support for fixed PHYs

Hello,

Here is a third version of the patch set that adds a Device Tree
binding and the related code to support fixed PHYs.

Since the second version, the changes have been:

 * Rebased on top of v3.14-rc1, and re-tested on hardware.

 * Removed the RFC tag, since there seems to be some real interest in
   this feature, and the code has gone through several iterations
   already.

 * The error handling in fixed_phy_register() has been fixed.

Since the first version, the changes have been:

 * Instead of using a 'fixed-link' property inside the Ethernet device
   DT node, with a fairly cryptic succession of integer values, we now
   use a PHY subnode under the Ethernet device DT node, with explicit
   properties to configure the duplex, speed, pause and other PHY
   properties.

 * The PHY address is automatically allocated by the kernel and no
   longer visible in the Device Tree binding.

 * The PHY device is created directly when the network driver calls
   of_phy_connect_fixed_link(), and associated to the PHY DT node,
   which allows the existing of_phy_connect() function to work,
   without the need to use the deprecated of_phy_connect_fixed_link().

Thanks,

Thomas
