MVEBU comphy drivers
|
|
--------------------
|
|
|
|
COMPHY controllers can be found on the following Marvell MVEBU SoCs:
|
|
* Armada 7k/8k (on the CP110)
|
|
* Armada 3700
|
|
It provides a number of shared PHYs used by various interfaces (network, SATA,
|
|
USB, PCIe...).
|
|
|
|
Required properties:
|
|
|
|
- compatible: should be one of:
|
|
* "marvell,comphy-cp110" for Armada 7k/8k
|
|
* "marvell,comphy-a3700" for Armada 3700
|
|
- reg: should contain the COMPHY register(s) location(s) and length(s).
|
|
* 1 entry for Armada 7k/8k
|
|
* 4 entries for Armada 3700 along with the corresponding reg-names
|
|
properties, memory areas are:
|
|
* Generic COMPHY registers
|
|
* Lane 1 (PCIe/GbE)
|
|
* Lane 0 (USB3/GbE)
|
|
* Lane 2 (SATA/USB3)
|
|
- marvell,system-controller: should contain a phandle to the system
|
|
controller node (only for Armada 7k/8k)
|
|
- #address-cells: should be 1.
|
|
- #size-cells: should be 0.
|
|
|
|
Optional properlties:
|
|
|
|
- clocks: pointers to the reference clocks for this device (CP110 only),
|
|
consequently: MG clock, MG Core clock, AXI clock.
|
|
- clock-names: names of used clocks for CP110 only, must be :
|
|
"mg_clk", "mg_core_clk" and "axi_clk".
|
|
|
|
A sub-node is required for each comphy lane provided by the comphy.
|
|
|
|
Required properties (child nodes):
|
|
|
|
- reg: COMPHY lane number.
|
|
- #phy-cells : from the generic PHY bindings, must be 1. Defines the
|
|
input port to use for a given comphy lane.
|
|
|
