Chris Packham 35a647f12c ARM: dts: armada-xp-98dx3236: combine dfx server nodes
Rather than having a separate node for the dfx server add a reg property
to the parent node. This give some compatibility with the Marvell
supplied SDK.

As no upstream driver currently exists for this block and support for
this SoC is still quite fresh in the kernel it should not be necessary
to retain a backwards compatible binding.

Marvell Prestera Switch Chip bindings
-------------------------------------
Required properties:
- compatible: 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";
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>;
};
