This patch set adds support for changing the Ethernet protocol at
runtime on Layerscape SoCs which have the Lynx 28G SerDes block.
The first two patches add a new generic PHY driver for the Lynx 28G and
the bindings file associated. The driver reads the PLL configuration at
probe time (the frequency provided to the lanes) and determines what
protocols can be supported.
Based on this the driver can deny or approve a request from the
dpaa2-mac to setup a new protocol.
The next 2 patches add some MC APIs for inquiring what is the running
version of firmware and setting up a new protocol on the MAC.
Moving along, we extract the code for setting up the supported
interfaces on a MAC on a different function since in the next patches
will update the logic.
In the next patch, the dpaa2-mac is updated so that it retrieves the
SerDes PHY based on the OF node and in case of a major reconfig, call
the PHY driver to set up the new protocol on the associated lane and the
MC firmware to reconfigure the MAC side of things.
Finally, the LX2160A dtsi is annotated with the SerDes PHY nodes for the
1st SerDes block. Beside this, the LX2160A Clearfog dtsi is annotated
with the 'phys' property for the exposed SFP cages.
Changes in v2:
