10 Required properties:
11
12 - compatible: should be one of:
13 * "marvell,comphy-cp110" for Armada 7k/8k

15 - reg: should contain the COMPHY register(s) l
16 * 1 entry for Armada 7k/8k
17 * 4 entries for Armada 3700 along with the c
18 properties, memory areas are:
19 * Generic COMPHY registers
20 * Lane 1 (PCIe/GbE)
21 * Lane 0 (USB3/GbE)
