[PATCH net-next v2 0/2] DP83822 Fiber enablement

[Dan Murphy <dmurphy@ti.com>]

Hello

The DP83822 Ethernet PHY has the ability to connect via a Fiber port.  The
derivative PHYs DP83825 and DP83826 do not have this ability. In fiber mode
the DP83822 disables auto negotiation and has a fixed 100Mbps speed with
support for full or half duplex modes.

A devicetree binding was added to set the signal polarity for the fiber
connection.  This property is only applicable if the FX_EN strap is set in
hardware other wise the signal loss detection is disabled on the PHY.

If the FX_EN is not strapped the device can be configured to run in fiber mode
via the device tree. All be it the PHY will not perfomr signal loss detection.
