====================
Add DT support for fixed PHYs
Here is a fourth version of the patch set that adds a Device Tree
binding and the related code to support fixed PHYs. I'm hoping to get
this merged in 3.16.
Changes since v3:
* Rebased on top of v3.15-rc5
* In patch "net: phy: decouple PHY id and PHY address in fixed PHY
driver", changed the PHY ID of fixed PHYs from 0xdeadbeef to 0x0,
as suggested by Grant Likely.
* Fixed the !CONFIG_PHY_FIXED case in patch "net: phy: extend fixed
driver with fixed_phy_register()". Noticed by Florian Fainelli.
* Added Acked-by from Grant Likely and Florian Fainelli on patch
"net: phy: extend fixed driver with fixed_phy_register()".
* Reworked the new fixed-link DT binding to be just a sub-node of the
Ethernet MAC node, and not a node referenced by the 'phy'
property. This was requested by Grant Likely.
* Reworked the code implementing the new DT binding to also make it
accept the old, single property based, DT binding.
* Added a patch that actually uses the new fixed link DT binding for
the Armada XP Matrix board.
Changes since v2:
* 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.
Changes since v1:
* 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().
