+node under the /reserved-memory node
+
+The BMan FBPR memory node must be named "bman-fbpr"

+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

+MediaTek PMIC Wrapper Driver
+
+This document describes the binding for the MediaTek PMIC wrapper.
+
+On MediaTek SoCs the PMIC is connected via SPI. The SPI master interface
+is not directly visible to the CPU, but only through the PMIC wrapper
+inside the SoC. The communication between the SoC and the PMIC can
+optionally be encrypted. Also a non standard Dual IO SPI mode can be
+used to increase speed.
+
+IP Pairing
+
+on MT8135 the pins of some SoC internal peripherals can be on the PMIC.
+The signals of these pins are routed over the SPI bus using the pwrap
+bridge. In the binding description below the properties needed for bridging
+are marked with "IP Pairing". These are optional on SoCs which do not support
+IP Pairing
+
+Required properties in pwrap device node.
+- compatible:
+ "mediatek,mt8135-pwrap" for MT8135 SoCs

+Keystone Navigator DMA Controller
+
+This document explains the device tree bindings for the packet dma
+on keystone devices. The Keystone Navigator DMA driver sets up the dma
+channels and flows for the QMSS(Queue Manager SubSystem) who triggers
+the actual data movements across clients using destination queues. Every
+client modules like NETCP(Network Coprocessor), SRIO(Serial Rapid IO),
+CRYPTO Engines etc has its own instance of dma hardware. QMSS has also
+an internal packet DMA module which is used as an infrastructure DMA
+with zero copy.
+
+Navigator DMA cloud layout:
+ ------------------
+ | Navigator DMAs |
+ ------------------
+ |
+ |-> DMA instance #0
+ |
+ |-> DMA instance #1
+ .
+ .
+ |
+ |-> DMA instance #n
+
+Navigator DMA properties:
+Required properties:
+ - compatible: Should be "ti,keystone-navigator-dma"
+ - clocks: phandle to dma instances clocks. The clock handles can be as
+ many as the dma instances. The order should be maintained as per
+ the dma instances.
+ - ti,navigator-cloud-address: Should contain base address for the multi-core
+ navigator cloud and number of addresses depends on SOC integration
+ configuration.. Navigator cloud global address needs to be programmed
+ into DMA and the DMA uses it as the physical addresses to reach queue
+ managers. Note that these addresses though points to queue managers,
+ they are relevant only from DMA perspective. The QMSS may not choose to
+ use them since it has a different address space view to reach all
+ its components.
+
+DMA instance properties:
+Required properties:
+ - reg: Should contain register location and length of the following dma
+ register regions. Register regions should be specified in the following
+ order.
+ - Global control register region (global).
+ - Tx DMA channel configuration register region (txchan).
+ - Rx DMA channel configuration register region (rxchan).
+ - Tx DMA channel Scheduler configuration register region (txsched).
+ - Rx DMA flow configuration register region (rxflow).
+
+Optional properties:
+ - reg-names: Names for the register regions.
+ - ti,enable-all: Enable all DMA channels vs clients opening specific channels
+ what they need. This property is useful for the userspace fast path
+ case where the linux drivers enables the channels used by userland
+ stack.
+ - ti,loop-back: To loopback Tx streaming I/F to Rx streaming I/F. Used for
+ infrastructure transfers.
+ - ti,rx-retry-timeout: Number of dma cycles to wait before retry on buffer
+ starvation.
+
+Example:
+
+ knav_dmas: knav_dmas@0 {
+ compatible = "ti,keystone-navigator-dma";
+ clocks = <&papllclk>, <&clkxge>;
+ #address-cells = <1>;

+
+Navigator DMA client:
+Required properties:
+ - ti,navigator-dmas: List of one or more DMA specifiers, each consisting of
+ - A phandle pointing to DMA instance node
+ - A DMA channel number as a phandle arg.
+ - ti,navigator-dma-names: Contains dma channel name for each DMA specifier in
+ the 'ti,navigator-dmas' property.

+* Texas Instruments Keystone Navigator Queue Management SubSystem driver
+
+The QMSS (Queue Manager Sub System) found on Keystone SOCs is one of
+the main hardware sub system which forms the backbone of the Keystone
+multi-core Navigator. QMSS consist of queue managers, packed-data structure
+processors(PDSP), linking RAM, descriptor pools and infrastructure
+Packet DMA.
+The Queue Manager is a hardware module that is responsible for accelerating
+management of the packet queues. Packets are queued/de-queued by writing or
+reading descriptor address to a particular memory mapped location. The PDSPs
+perform QMSS related functions like accumulation, QoS, or event management.
+Linking RAM registers are used to link the descriptors which are stored in
+descriptor RAM. Descriptor RAM is configurable as internal or external memory.
+The QMSS driver manages the PDSP setups, linking RAM regions,
+queue pool management (allocation, push, pop and notify) and descriptor
+pool management.
+
+
+Required properties:
+- compatible : Must be "ti,keystone-navigator-qmss";
+- clocks : phandle to the reference clock for this device.
+- queue-range : <start number> total range of queue numbers for the device.
+- linkram0 : <address size> for internal link ram, where size is the total
+ link ram entries.
+- linkram1 : <address size> for external link ram, where size is the total
+ external link ram entries. If the address is specified as "0"
+ driver will allocate memory.
+- qmgrs : child node describing the individual queue managers on the
+ SoC. On keystone 1 devices there should be only one node.
+ On keystone 2 devices there can be more than 1 node.
+ -- managed-queues : the actual queues managed by each queue manager
+ instance, specified as <"base queue #" "# of queues">.
+ -- reg : Address and size of the register set for the device.
+ Register regions should be specified in the following
+ order
+ - Queue Peek region.
+ - Queue status RAM.
+ - Queue configuration region.
+ - Descriptor memory setup region.
+ - Queue Management/Queue Proxy region for queue Push.
+ - Queue Management/Queue Proxy region for queue Pop.
+- queue-pools : child node classifying the queue ranges into pools.
+ Queue ranges are grouped into 3 type of pools:
+ - qpend : pool of qpend(interruptible) queues
+ - general-purpose : pool of general queues, primarly used
+ as free descriptor queues or the
+ transmit DMA queues.
+ - accumulator : pool of queues on PDSP accumulator channel
+ Each range can have the following properties:
+ -- qrange : number of queues to use per queue range, specified as
+ <"base queue #" "# of queues">.
+ -- interrupts : Optional property to specify the interrupt mapping
+ for interruptible queues. The driver additionaly sets
+ the interrupt affinity hint based on the cpu mask.
+ -- qalloc-by-id : Optional property to specify that the queues in this
+ range can only be allocated by queue id.
+ -- accumulator : Accumulator channel specification. Any of the PDSPs in
+ QMSS can be loaded with the accumulator firmware. The
+ accumulator firmware’s job is to poll a select number of
+ queues looking for descriptors that have been pushed
+ into them. Descriptors are popped from the queue and
+ placed in a buffer provided by the host. When the list
+ becomes full or a programmed time period expires, the
+ accumulator triggers an interrupt to the host to read
+ the buffer for descriptor information. This firmware
+ comes in 16, 32, and 48 channel builds. Each of these
+ channels can be configured to monitor 32 contiguous
+ queues. Accumulator channel property is specified as:
+ <pdsp-id, channel, entries, pacing mode, latency>
+ pdsp-id : QMSS PDSP running accumulator firmware
+ on which the channel has to be
+ configured
+ channel : Accumulator channel number
+ entries : Size of the accumulator descriptor list
+ pacing mode : Interrupt pacing mode
+ 0 : None, i.e interrupt on list full only
+ 1 : Time delay since last interrupt
+ 2 : Time delay since first new packet
+ 3 : Time delay since last new packet
+ latency : time to delay the interrupt, specified
+ in microseconds.
+ -- multi-queue : Optional property to specify that the channel has to
+ monitor upto 32 queues starting at the base queue #.
+- descriptor-regions : child node describing the memory regions for keystone
+ navigator packet DMA descriptors. The memory for
+ descriptors will be allocated by the driver.
+ -- id : region number in QMSS.
+ -- region-spec : specifies the number of descriptors in the
+ region, specified as
+ <"# of descriptors" "descriptor size">.
+ -- link-index : start index, i.e. index of the first
+ descriptor in the region.
+
+Optional properties:
+- dma-coherent : Present if DMA operations are coherent.
+- pdsps : child node describing the PDSP configuration.
+ -- firmware : firmware to be loaded on the PDSP.
+ -- id : the qmss pdsp that will run the firmware.
+ -- reg : Address and size of the register set for the PDSP.
+ Register regions should be specified in the following
+ order
+ - PDSP internal RAM region.
+ - PDSP control/status region registers.
+ - QMSS interrupt distributor registers.
+ - PDSP command interface region.
+
+Example:
+
