dt-bindings: soc: fsl: Convert q(b)man-* to yaml format
Convert qman, bman, qman-portals, bman-portals to yaml format. Additional Change for fsl,q(b)man-portal: - Only keep one example. - Add fsl,qman-channel-id property. - Use interrupt type macro. - Remove top level qman-portals@ff4200000 at example. Additional change for fsl,q(b)man: - Fixed example error. - Remove redundent part, only keep fsl,qman node. - Change memory-regions to memory-region. - fsl,q(b)man-portals is not required property Additional change for fsl,qman-fqd.yaml: - Fixed example error. - Only keep one example. - Ref to reserve-memory.yaml - Merge fsl,bman reserver memory part Signed-off-by: Frank Li <Frank.Li@nxp.com> Link: https://lore.kernel.org/r/20240626193753.2088926-1-Frank.Li@nxp.com Signed-off-by: Rob Herring (Arm) <robh@kernel.org>

BMan Private Memory Node
|
||||
|
||||
BMan requires a contiguous range of physical memory used for the backing store
|
||||
for BMan Free Buffer Proxy Records (FBPR). This memory is reserved/allocated as
|
||||
a node under the /reserved-memory node.
|
||||
|
||||
The BMan FBPR memory node must be named "bman-fbpr"
|
||||
|
||||
PROPERTIES
|
||||
|
||||
- compatible
|
||||
Usage: required
|
||||
Value type: <stringlist>
|
||||
Definition: PPC platforms: Must include "fsl,bman-fbpr"
|
||||
ARM platforms: Must include "shared-dma-pool"
|
||||
as well as the "no-map" property
|
||||
|
||||
The following constraints are relevant to the FBPR private memory:
|
||||
- The size must be 2^(size + 1), with size = 11..33. That is 4 KiB to
|
||||
16 GiB
|
||||
- The alignment must be a muliptle of the memory size
|
||||
|
||||
The size of the FBPR must be chosen by observing the hardware features configured
|
||||
via the Reset Configuration Word (RCW) and that are relevant to a specific board
|
||||
(e.g. number of MAC(s) pinned-out, number of offline/host command FMan ports,
|
||||
etc.). The size configured in the DT must reflect the hardware capabilities and
|
||||
not the specific needs of an application
|
||||
|
||||
For additional details about reserved memory regions see reserved-memory.txt
|
||||
|
||||
EXAMPLE
|
||||
|
||||
The example below shows a BMan FBPR dynamic allocation memory node
|
||||
|
||||
reserved-memory {
|
||||
#address-cells = <2>;
|
||||
#size-cells = <2>;
|
||||
ranges;
|
||||
|
||||
bman_fbpr: bman-fbpr {
|
||||
compatible = "shared-mem-pool";
|
||||
size = <0 0x1000000>;
|
||||
alignment = <0 0x1000000>;
|
||||
no-map;
|
||||
};
|
||||
};
|
||||
|

QMan Private Memory Nodes
|
||||
|
||||
QMan requires two contiguous range of physical memory used for the backing store
|
||||
for QMan Frame Queue Descriptor (FQD) and Packed Frame Descriptor Record (PFDR).
|
||||
This memory is reserved/allocated as a node under the /reserved-memory node.
|
||||
|
||||
For additional details about reserved memory regions see reserved-memory.txt
|
||||
|
||||
The QMan FQD memory node must be named "qman-fqd"
|
||||
|
||||
PROPERTIES
|
||||
|
||||
- compatible
|
||||
Usage: required
|
||||
Value type: <stringlist>
|
||||
Definition: PPC platforms: Must include "fsl,qman-fqd"
|
||||
ARM platforms: Must include "shared-dma-pool"
|
||||
as well as the "no-map" property
|
||||
|
||||
The QMan PFDR memory node must be named "qman-pfdr"
|
||||
|
||||
PROPERTIES
|
||||
|
||||
- compatible
|
||||
Usage: required
|
||||
Value type: <stringlist>
|
||||
Definition: PPC platforms: Must include "fsl,qman-pfdr"
|
||||
ARM platforms: Must include "shared-dma-pool"
|
||||
as well as the "no-map" property
|
||||
|
||||
The following constraints are relevant to the FQD and PFDR private memory:
|
||||
- The size must be 2^(size + 1), with size = 11..29. That is 4 KiB to
|
||||
1 GiB
|
||||
- The alignment must be a muliptle of the memory size
|
||||
|
||||
The size of the FQD and PFDP must be chosen by observing the hardware features
|
||||
configured via the Reset Configuration Word (RCW) and that are relevant to a
|
||||
specific board (e.g. number of MAC(s) pinned-out, number of offline/host command
|
||||
FMan ports, etc.). The size configured in the DT must reflect the hardware
|
||||
capabilities and not the specific needs of an application
|
||||
|
||||
For additional details about reserved memory regions see reserved-memory.txt
|
||||
|
||||
EXAMPLE
|
||||
|
||||
The example below shows a QMan FQD and a PFDR dynamic allocation memory nodes

#size-cells = <2>;
