-CONTENTS
-
- - QMan Portal
- - Example
-
-QMan Portal Node
-
-Portals are memory mapped interfaces to QMan that allow low-latency, lock-less
-interaction by software running on processor cores, accelerators and network
-interfaces with the QMan
-
-PROPERTIES
-
-- compatible
- Usage: Required
- Value type: <stringlist>
- Definition: Must include "fsl,qman-portal-<hardware revision>"
- May include "fsl,<SoC>-qman-portal" or "fsl,qman-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
-
-- fsl,liodn
- Usage: See pamu.txt
- Value type: <prop-encoded-array>
- Definition: Two LIODN(s). DQRR LIODN (DLIODN) and Frame LIODN
- (FLIODN)
-
-- fsl,iommu-parent
- Usage: See pamu.txt
- Value type: <phandle>
- Definition: PAMU property used for dynamic LIODN assignment
-
- For additional details about the PAMU/LIODN binding(s) see pamu.txt
-
-- cell-index
- Usage: Required
- Value type: <u32>
- Definition: The hardware index of the channel. This can also be
- determined by dividing any of the channel's 8 work queue
- IDs by 8
-
-In addition to these properties the qman-portals should have sub-nodes to
-represent the HW devices/portals that are connected to the software portal
-described here
-
-The currently supported sub-nodes are:
- * fman0
- * fman1
- * pme
- * crypto
-
-These subnodes should have the following properties:
-
-- fsl,liodn
- Usage: See pamu.txt
- Value type: <prop-encoded-array>
- Definition: PAMU property used for static LIODN assignment
-
-- fsl,iommu-parent
- Usage: See pamu.txt
- Value type: <phandle>
- Definition: PAMU property used for dynamic LIODN assignment
-
-- dev-handle
- Usage: Required
- Value type: <phandle>
- Definition: The phandle to the particular hardware device that this
- portal is connected to.
-
