- - 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>;
