CONTENTS

	- BMan Portal

	- Example

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>;

		};
