+* Spreadtrum DMA controller
+
+This binding follows the generic DMA bindings defined in dma.txt.

+Required properties:
+- compatible: Should be "sprd,sc9860-dma".
+- reg: Should contain DMA registers location and length.
+- interrupts: Should contain one interrupt shared by all channel.
+- #dma-cells: must be <1>. Used to represent the number of integer
+	cells in the dmas property of client device.
+- #dma-channels : Number of DMA channels supported. Should be 32.
+- clock-names: Should contain the clock of the DMA controller.
+- clocks: Should contain a clock specifier for each entry in clock-names.

+* STMicroelectronics STM32 MDMA controller
+
+The STM32 MDMA is a general-purpose direct memory access controller capable of
+supporting 64 independent DMA channels with 256 HW requests.
+
+Required properties:
+- compatible: Should be "st,stm32h7-mdma"
+- reg: Should contain MDMA registers location and length. This should include
+  all of the per-channel registers.
+- interrupts: Should contain the MDMA interrupt.
+- clocks: Should contain the input clock of the DMA instance.
+- resets: Reference to a reset controller asserting the DMA controller.
+- #dma-cells : Must be <5>. See DMA client paragraph for more details.

+	0x00: Source address pointer is fixed
+	0x10: Source address pointer is incremented after each data transfer
+	0x11: Source address pointer is decremented after each data transfer

+	0x00: Destination address pointer is fixed
+	0x10: Destination address pointer is incremented after each data
+	transfer
+	0x11: Destination address pointer is decremented after each data
+	transfer
+ -bit 8-9: Source increment offset size

+-bit 25-18: The number of bytes to be transferred in a single transfer
+	(min = 1 byte, max = 128 bytes)
+-bit 29:28: Trigger Mode
+	0x00: Each MDMA request triggers a buffer transfer (max 128 bytes)
+	0x01: Each MDMA request triggers a block transfer (max 64K bytes)
+	0x10: Each MDMA request triggers a repeated block transfer
+	0x11: Each MDMA request triggers a linked list transfer
+4. A 32bit value specifying the register to be used to acknowledge the request
+   if no HW ack signal is used by the MDMA client
