BMan Portal Node

Portals are memory mapped interfaces to BMan that allow low-latency, lock-less
interaction by software running on processor cores, accelerators and network
interfaces with the BMan

PROPERTIES

- compatible
	Usage:		Required
	Value type:	<stringlist>
	Definition:	Must include "fsl,bman-portal-<hardware revision>"
			May include "fsl,<SoC>-bman-portal" or "fsl,bman-portal"

- reg
	Usage:		Required
	Value type:	<prop-encoded-array>
	Definition:	Two regions. The first is the cache-enabled region of
			the portal. The second is the cache-inhibited region of
			the portal

- interrupts
	Usage:		Required
	Value type:	<prop-encoded-array>
	Definition:	Standard property

EXAMPLE

The example below shows a (P4080) BMan portals container/bus node with two portals

bman-portals@ff4000000 {
		#address-cells = <1>;
		#size-cells = <1>;
		compatible = "simple-bus";
		ranges = <0 0xf 0xf4000000 0x200000>;

bman-portal@0 {
			compatible = "fsl,bman-portal-1.0.0", "fsl,bman-portal";
			reg = <0x0 0x4000>, <0x100000 0x1000>;
			interrupts = <105 2 0 0>;
		};
		bman-portal@4000 {
			compatible = "fsl,bman-portal-1.0.0", "fsl,bman-portal";
			reg = <0x4000 0x4000>, <0x101000 0x1000>;
			interrupts = <107 2 0 0>;
		};
