Chris Packham 40ad192f9e dt-bindings: marvell,prestera: Add common compatible string
Add "marvell,prestera" as a compatible string so that drivers can be
written to account for any prestera variant without needing to
specialise to the more specific values.

Marvell Prestera Switch Chip bindings
-------------------------------------
Required properties:
- compatible: must be "marvell,prestera" and one of the following
"marvell,prestera-98dx3236",
"marvell,prestera-98dx3336",
"marvell,prestera-98dx4251",
- reg: address and length of the register set for the device.
- interrupts: interrupt for the device
Optional properties:
- dfx: phandle reference to the "DFX Server" node
Example:
switch {
compatible = "simple-bus";
#address-cells = <1>;
#size-cells = <1>;
ranges = <0 MBUS_ID(0x03, 0x00) 0 0x100000>;
packet-processor@0 {
compatible = "marvell,prestera-98dx3236", "marvell,prestera";
reg = <0 0x4000000>;
interrupts = <33>, <34>, <35>;
dfx = <&dfx>;
};
};
DFX Server bindings
-------------------
Required properties:
- compatible: must be "marvell,dfx-server", "simple-bus"
- ranges: describes the address mapping of a memory-mapped bus.
- reg: address and length of the register set for the device.
Example:
dfx-server {
compatible = "marvell,dfx-server", "simple-bus";
#address-cells = <1>;
#size-cells = <1>;
ranges = <0 MBUS_ID(0x08, 0x00) 0 0x100000>;
reg = <MBUS_ID(0x08, 0x00) 0 0x100000>;
};
