phy driver

phy driver

[Barbier, Renaud]

I am working on a LS1021A currently booting from SPI NOR. 
I am having difficulties to get the network port working.
Issue is that the PHY AR8033 is not initialized properly and even though I get the correct speed/duplex at first (1000FD), no data go through.
Clearing/writing 0x100 to the phy control register then gives the lowest speed/duplex(10HD) and ping works.

The at803.c phy driver is now enabled but I do not see the driver probe function being called and neither mdio_bus_match.
I see a few examples of device trees to add the properties found in the driver. What else am I missing for the at803 to be used.

Cheers,
Renaud

I found a few boards support that fixup. It is likely it will work for the LS1021 AR8033
