+description: |
+  Apple's Audio DMA Controller (ADMAC) is used to fetch and store audio samples
+  on SoCs from the "Apple Silicon" family.
+
+  The controller has been seen with up to 24 channels. Even-numbered channels
+  are TX-only, odd-numbered are RX-only. Individual channels are coupled to

+description:
+  The Atmel Direct Memory Access Controller (DMAC) transfers data from a source
+  peripheral to a destination peripheral over one or more AMBA buses. One channel
+  is required for each source/destination pair. In the most basic configuration,
+  the DMAC has one master interface and one channel. The master interface reads
+  the data from a source and writes it to a destination. Two AMBA transfers are
+  required for each DMAC data transfer. This is also known as a dual-access transfer.
+  The DMAC is programmed via the APB interface.

+description: |
+  The eDMA channels have multiplex capability by programmable
+  memory-mapped registers. channels are split into two groups, called
+  DMAMUX0 and DMAMUX1, specific DMA request source can only be multiplexed
+  by any channel of certain group, DMAMUX0 or DMAMUX1, but not both.
+
+  This binding has an inverted dma-channel-mask definition compared to
+  the common DMA binding for historical reasons.

+* IMG Multi-threaded DMA Controller (MDC)
+
+Required properties:
+- compatible: Must be "img,pistachio-mdc-dma".
+- reg: Must contain the base address and length of the MDC registers.
+- interrupts: Must contain all the per-channel DMA interrupts.
+- clocks: Must contain an entry for each entry in clock-names.
+  See ../clock/clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+  - sys: MDC system interface clock.
+- img,cr-periph: Must contain a phandle to the peripheral control syscon
+  node which contains the DMA request to channel mapping registers.
+- img,max-burst-multiplier: Must be the maximum supported burst size multiplier.
+  The maximum burst size is this value multiplied by the hardware-reported bus
+  width.
+- #dma-cells: Must be 3:
+  - The first cell is the peripheral's DMA request line.
+  - The second cell is a bitmap specifying to which channels the DMA request
+    line may be mapped (i.e. bit N set indicates channel N is usable).
+  - The third cell is the thread ID to be used by the channel.
+
+Optional properties:
+- dma-channels: Number of supported DMA channels, up to 32.  If not specified
+  the number reported by the hardware is used.
+

+* Hisilicon K3 DMA controller
+
+See dma.txt first
+
+Required properties:
+- compatible: Must be one of
+-              "hisilicon,k3-dma-1.0"
+-              "hisilicon,hisi-pcm-asp-dma-1.0"
+- reg: Should contain DMA registers location and length.
+- interrupts: Should contain one interrupt shared by all channel
+- #dma-cells: see dma.txt, should be 1, para number
+- dma-channels: physical channels supported
+- dma-requests: virtual channels supported, each virtual channel
+		have specific request line
+- clocks: clock required
+
+Example:
+
+Controller:
+		dma0: dma@fcd02000 {

+			dma-requests = <27>;
+			interrupts = <0 12 4>;
+			clocks = <&pclk>;
+		};
+
+Client:
+Use specific request line passing from dmax
+For example, i2c0 read channel request line is 18, while write channel use 19
+
+		i2c0: i2c@fcb08000 {

+* DMA controller
+
+Required properties
+
+- compatible:	must be one of
+		"renesas,nbpfaxi64dmac1b4"
+		"renesas,nbpfaxi64dmac1b8"
+		"renesas,nbpfaxi64dmac1b16"
+		"renesas,nbpfaxi64dmac4b4"
+		"renesas,nbpfaxi64dmac4b8"

+		"renesas,nbpfaxi64dmac8b4"
+		"renesas,nbpfaxi64dmac8b8"
+		"renesas,nbpfaxi64dmac8b16"
+- #dma-cells:	must be 2: the first integer is a terminal number, to which this
+		slave is connected, the second one is flags. Flags is a bitmask
+		with the following bits defined:
+
+#define NBPF_SLAVE_RQ_HIGH	1
+#define NBPF_SLAVE_RQ_LOW	2
+#define NBPF_SLAVE_RQ_LEVEL	4
+
+Optional properties:
+- max-burst-mem-read:	limit burst size for memory reads
+  (DMA_MEM_TO_MEM/DMA_MEM_TO_DEV) to this value, specified in bytes, rather
+  than using the maximum burst size allowed by the hardware's buffer size.
+- max-burst-mem-write:	limit burst size for memory writes
+  (DMA_DEV_TO_MEM/DMA_MEM_TO_MEM) to this value, specified in bytes, rather
+  than using the maximum burst size allowed by the hardware's buffer size.
+  If both max-burst-mem-read and max-burst-mem-write are set, DMA_MEM_TO_MEM
+  will use the lower value.
+
+You can use dma-channels and dma-requests as described in dma.txt, although they
+won't be used, this information is derived from the compatibility string.
+
+Example:
+
+	dma: dma-controller@48000000 {
+		compatible = "renesas,nbpfaxi64dmac8b4";
+		reg = <0x48000000 0x400>;

+			      0 15 0x4
+			      0 16 0x4
+			      0 17 0x4
+			      0 18 0x4
+			      0 19 0x4>;
+		#dma-cells = <2>;
+		dma-channels = <8>;
+		dma-requests = <8>;
+	};
+
+* DMA client
+
+Required properties:
+
+dmas and dma-names are required, as described in dma.txt.
+
+Example:
+
+#include <dt-bindings/dma/nbpfaxi.h>
+
+...
+		dmas = <&dma 0 (NBPF_SLAVE_RQ_HIGH | NBPF_SLAVE_RQ_LEVEL)
+			&dma 1 (NBPF_SLAVE_RQ_HIGH | NBPF_SLAVE_RQ_LEVEL)>;

+description: |
+  The STM32 DMA is a general-purpose direct memory access controller capable of
+  supporting 8 independent DMA channels. Each channel can have up to 8 requests.
+  DMA clients connected to the STM32 DMA controller must use the format
+  described in the dma.txt file, using a four-cell specifier for each
+  channel: a phandle to the DMA controller plus the following four integer cells:
+    1. The channel id
+    2. The request line number
+    3. A 32bit mask specifying the DMA channel configuration which are device
+      dependent:
+        -bit 9: Peripheral Increment Address
+          0x0: no address increment between transfers
+          0x1: increment address between transfers
+        -bit 10: Memory Increment Address
+          0x0: no address increment between transfers
+          0x1: increment address between transfers
+        -bit 15: Peripheral Increment Offset Size
+          0x0: offset size is linked to the peripheral bus width
+          0x1: offset size is fixed to 4 (32-bit alignment)
+        -bit 16-17: Priority level
+          0x0: low
+          0x1: medium
+          0x2: high
+          0x3: very high
+    4. A 32bit bitfield value specifying DMA features which are device dependent:

+         0x0: 1/4 full FIFO
+         0x1: 1/2 full FIFO

+         0x3: full FIFO
+       -bit 2: DMA direct mode
+         0x0: FIFO mode with threshold selectable with bit 0-1
+         0x1: Direct mode: each DMA request immediately initiates a transfer
+              from/to the memory, FIFO is bypassed.
+       -bit 4: alternative DMA request/acknowledge protocol
+         0x0: Use standard DMA ACK management, where ACK signal is maintained
+              up to the removal of request and transfer completion
+         0x1: Use alternative DMA ACK management, where ACK de-assertion does
+              not wait for the de-assertion of the REQuest, ACK is only managed
+              by transfer completion. This must only be used on channels
+              managing transfers for STM32 USART/UART.

+
+description: |
+  The STM32 DMA3 is a direct memory access controller with different features
+  depending on its hardware configuration.
+  It is either called LPDMA (Low Power), GPDMA (General Purpose) or HPDMA (High
+  Performance).
+  Its hardware configuration registers allow to dynamically expose its features.
+
+  GPDMA and HPDMA support 16 independent DMA channels, while only 4 for LPDMA.
+  GPDMA and HPDMA support 256 DMA requests from peripherals, 8 for LPDMA.
+
+  Bindings are generic for these 3 STM32 DMA3 configurations.
+
+  DMA clients connected to the STM32 DMA3 controller must use the format
+  described in "#dma-cells" property description below, using a three-cell
+  specifier for each channel.

+description: |
+  The Block Copy DMA (BCDMA) is intended to perform similar functions as the TR
+  mode channels of K3 UDMA-P.
+  BCDMA includes block copy channels and Split channels.
+
+  Block copy channels mainly used for memory to memory transfers, but with
+  optional triggers a block copy channel can service peripherals by accessing
+  directly to memory mapped registers or area.
+
+  Split channels can be used to service PSI-L based peripherals.
+  The peripherals can be PSI-L native or legacy, non PSI-L native peripherals
+  with PDMAs. PDMA is tasked to act as a bridge between the PSI-L fabric and the
+  legacy peripheral.
+
+  PDMAs can be configured via BCDMA split channel's peer registers to match with
+  the configuration of the legacy peripheral.

+description: |
+  The UDMA-P is intended to perform similar (but significantly upgraded)
+  functions as the packet-oriented DMA used on previous SoC devices. The UDMA-P
+  module supports the transmission and reception of various packet types.
+  The UDMA-P architecture facilitates the segmentation and reassembly of SoC DMA
+  data structure compliant packets to/from smaller data blocks that are natively
+  compatible with the specific requirements of each connected peripheral.
+  Multiple Tx and Rx channels are provided within the DMA which allow multiple
+  segmentation or reassembly operations to be ongoing. The DMA controller
+  maintains state information for each of the channels which allows packet
+  segmentation and reassembly operations to be time division multiplexed between
+  channels in order to share the underlying DMA hardware. An external DMA
+  scheduler is used to control the ordering and rate at which this multiplexing
+  occurs for Transmit operations. The ordering and rate of Receive operations
+  is indirectly controlled by the order in which blocks are pushed into the DMA
+  on the Rx PSI-L interface.
+
+  The UDMA-P also supports acting as both a UTC and UDMA-C for its internal
+  channels. Channels in the UDMA-P can be configured to be either Packet-Based
+  or Third-Party channels on a channel by channel basis.
+
+  All transfers within NAVSS is done between PSI-L source and destination
+  threads.
+  The peripherals serviced by UDMA can be PSI-L native (sa2ul, cpsw, etc) or
+  legacy, non PSI-L native peripherals. In the later case a special, small PDMA
+  is tasked to act as a bridge between the PSI-L fabric and the legacy
+  peripheral.
+
+  PDMAs can be configured via UDMAP peer registers to match with the
+  configuration of the legacy peripheral.
