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>

The Buffer Manager is part of the Data-Path Acceleration Architecture (DPAA).
|
|
BMan supports hardware allocation and deallocation of buffers belonging to
|
|
pools originally created by software with configurable depletion thresholds.
|
|
This binding covers the CCSR space programming model

List of phandles referencing the BMan private memory

nodes (described below). The bman-fqd node must be

first followed by bman-pfdr node. Only used on ARM

Devices connected to a BMan instance via Direct Connect Portals (DCP) must link

to the respective BMan instance
