As stated in marvell-orion-mdio.txt deleted in commit 0781434af811f
("dt-bindings: net: orion-mdio: Convert to JSON schema") if
'interrupts' property is present, width of 'reg' should be 0x84.
Otherwise, width of 'reg' should be 0x4. Fix 'examples:' and add
constraints checking whether 'interrupts' property is present
and validate it against fixed values in reg.

|
|
The Ethernet controllers of the Marvel Kirkwood, Dove, Orion5x, MV78xx0,
|
|
Armada 370, Armada XP, Armada 7k and Armada 8k have an identical unit that
|
|
provides an interface with the MDIO bus. Additionally, Armada 7k and Armada
|
|
8k has a second unit which provides an interface with the xMDIO bus. This
|
|
driver handles these interfaces.
