Kernel-4.18.0-80.el8_marvell-pp2

• Marvell Armada 375 Ethernet Controller (PPv2.1)
  Marvell Armada 7K/8K Ethernet Controller (PPv2.2)

Required properties:

• compatible: should be one of:
  “marvell,armada-375-pp2”
  “marvell,armada-7k-pp2”

• reg: addresses and length of the register sets for the device.
  For “marvell,armada-375-pp2”, must contain the following register
  sets:

  • common controller registers
  • LMS registers
  • one register area per Ethernet port
    For “marvell,armada-7k-pp2”, must contain the following register
    sets:
  • packet processor registers
  • networking interfaces registers

• clocks: pointers to the reference clocks for this device, consequently:

  • main controller clock (for both armada-375-pp2 and armada-7k-pp2)
  • GOP clock (for both armada-375-pp2 and armada-7k-pp2)
  • MG clock (only for armada-7k-pp2)
  • MG Core clock (only for armada-7k-pp2)
  • AXI clock (only for armada-7k-pp2)

• clock-names: names of used clocks, must be “pp_clk”, “gop_clk”, “mg_clk”,
  “mg_core_clk” and “axi_clk” (the 3 latter only for armada-7k-pp2).

The ethernet ports are represented by subnodes. At least one port is
required.

Required properties (port):

• interrupts: interrupt for the port
• port-id: ID of the port from the MAC point of view
• gop-port-id: only for marvell,armada-7k-pp2, ID of the port from the
  GOP (Group Of Ports) point of view. This ID is used to index the
  per-port registers in the second register area.
• phy-mode: See ethernet.txt file in the same directory

Optional properties (port):

• marvell,loopback: port is loopback mode
• phy: a phandle to a phy node defining the PHY address (as the reg
  property, a single integer).
• interrupt-names: if more than a single interrupt for rx is given, must

               be the name associated to the interrupts listed. Valid
               names are: "tx-cpu0", "tx-cpu1", "tx-cpu2", "tx-cpu3",
       "rx-shared", "link".
  

• marvell,system-controller: a phandle to the system controller.
