+ 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

- Use "dma-shared-all" for the common interrupt line
- that is shared by all dma channels.

-* Freescale enhanced Direct Memory Access(eDMA) Controller
-
- The eDMA channels have multiplex capability by programmble 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.
-
-* eDMA Controller
-Required properties:
-- compatible :
- - "fsl,vf610-edma" for eDMA used similar to that on Vybrid vf610 SoC
- - "fsl,imx7ulp-edma" for eDMA2 used similar to that on i.mx7ulp
- - "fsl,ls1028a-edma" followed by "fsl,vf610-edma" for eDMA used on the
- LS1028A SoC.
-- reg : Specifies base physical address(s) and size of the eDMA registers.
- The 1st region is eDMA control register's address and size.
- The 2nd and the 3rd regions are programmable channel multiplexing
- control register's address and size.
-- interrupts : A list of interrupt-specifiers, one for each entry in
- interrupt-names on vf610 similar SoC. But for i.mx7ulp per channel
- per transmission interrupt, total 16 channel interrupt and 1
- error interrupt(located in the last), no interrupt-names list on
- i.mx7ulp for clean on dts.
-- #dma-cells : Must be <2>.
- The 1st cell specifies the DMAMUX(0 for DMAMUX0 and 1 for DMAMUX1).
- Specific request source can only be multiplexed by specific channels
- group called DMAMUX.
- The 2nd cell specifies the request source(slot) ID.
- See the SoC's reference manual for all the supported request sources.
-- dma-channels : Number of channels supported by the controller
-- clock-names : A list of channel group clock names. Should contain:
- "dmamux0" - clock name of mux0 group
- "dmamux1" - clock name of mux1 group
- Note: No dmamux0 on i.mx7ulp, but another 'dma' clk added on i.mx7ulp.
-- clocks : A list of phandle and clock-specifier pairs, one for each entry in
- clock-names.
-
-Optional properties:
-- big-endian: If present registers and hardware scatter/gather descriptors
- of the eDMA are implemented in big endian mode, otherwise in little
- mode.
-- interrupt-names : Should contain the below on vf610 similar SoC but not used
- on i.mx7ulp similar SoC:
- "edma-tx" - the transmission interrupt
- "edma-err" - the error interrupt

-* DMA clients

-
-The fsl,sdma-event-remap property in this case has two values:
-- <0 15 1> means that the offset is 0, so GPR0 is the register of the
-SDMA remap. Bit 15 of GPR0 selects between UART4_RX and SAI1_RX.
-Setting bit 15 to 1 selects SAI1_RX.
-- <0 16 1> means that the offset is 0, so GPR0 is the register of the
-SDMA remap. Bit 16 of GPR0 selects between UART4_TX and SAI1_TX.
-Setting bit 16 to 1 selects SAI1_TX.

-QCOM ADM DMA Controller
-
-Required properties:
-- compatible: must contain "qcom,adm" for IPQ/APQ8064 and MSM8960
-- reg: Address range for DMA registers
-- interrupts: Should contain one interrupt shared by all channels
-- #dma-cells: must be <2>. First cell denotes the channel number. Second cell
- denotes CRCI (client rate control interface) flow control assignment.
-- clocks: Should contain the core clock and interface clock.
-- clock-names: Must contain "core" for the core clock and "iface" for the
- interface clock.
-- resets: Must contain an entry for each entry in reset names.
-- reset-names: Must include the following entries:
- - clk
- - c0
- - c1
- - c2
-- qcom,ee: indicates the security domain identifier used in the secure world.
-
-Example:
- adm_dma: dma@18300000 {
- compatible = "qcom,adm";
- reg = <0x18300000 0x100000>;
- interrupts = <0 170 0>;
- #dma-cells = <2>;
-
- clocks = <&gcc ADM0_CLK>, <&gcc ADM0_PBUS_CLK>;
- clock-names = "core", "iface";
-
- resets = <&gcc ADM0_RESET>,
- <&gcc ADM0_C0_RESET>,
- <&gcc ADM0_C1_RESET>,
- <&gcc ADM0_C2_RESET>;
- reset-names = "clk", "c0", "c1", "c2";
- qcom,ee = <0>;
- };
-
-DMA clients must use the format descripted in the dma.txt file, using a three
-cell specifier for each channel.
-
-Each dmas request consists of 3 cells:
- 1. phandle pointing to the DMA controller
- 2. channel number
- 3. CRCI assignment, if applicable. If no CRCI flow control is required, use 0.
- The CRCI is used for flow control. It identifies the peripheral device that
- is the source/destination for the transferred data.
-
-Example:
-
- spi4: spi@1a280000 {
- spi-max-frequency = <50000000>;
-
- pinctrl-0 = <&spi_pins>;
- pinctrl-names = "default";
-
- cs-gpios = <&qcom_pinmux 20 0>;
-
- dmas = <&adm_dma 6 9>,
- <&adm_dma 5 10>;
- dma-names = "rx", "tx";

-- reg: Address range for DMA registers
-- interrupts: Should contain the one interrupt shared by all channels
-- #dma-cells: must be <1>, the cell in the dmas property of the client device
- represents the channel number
-- clocks: required clock
-- clock-names: must contain "bam_clk" entry
-- qcom,ee : indicates the active Execution Environment identifier (0-7) used in
- the secure world.
-- qcom,controlled-remotely : optional, indicates that the bam is controlled by
- remote proccessor i.e. execution environment.
-- qcom,powered-remotely : optional, indicates that the bam is powered up by
- a remote processor but must be initialized by the local processor.
-- num-channels : optional, indicates supported number of DMA channels in a
- remotely controlled bam.
-- qcom,num-ees : optional, indicates supported number of Execution Environments
- in a remotely controlled bam.

-* DMA40 DMA Controller
-
-Required properties:
-- compatible: "stericsson,dma40"
-- reg: Address range of the DMAC registers
-- reg-names: Names of the above areas to use during resource look-up
-- interrupt: Should contain the DMAC interrupt number
-- #dma-cells: must be <3>
-- memcpy-channels: Channels to be used for memcpy
-
-Optional properties:
-- dma-channels: Number of channels supported by hardware - if not present
- the driver will attempt to obtain the information from H/W
-- disabled-channels: Channels which can not be used
-
-Example:
-
- dma: dma-controller@801c0000 {
- compatible = "stericsson,db8500-dma40", "stericsson,dma40";
- reg = <0x801C0000 0x1000 0x40010000 0x800>;

- interrupt-parent = <&intc>;
- interrupts = <0 25 0x4>;
-
- #dma-cells = <2>;
- memcpy-channels = <56 57 58 59 60>;
- disabled-channels = <12>;
- dma-channels = <8>;
- };
-
-Clients
-Required properties:
-- dmas: Comma separated list of dma channel requests
-- dma-names: Names of the aforementioned requested channels
-
-Each dmas request consists of 4 cells:
- 1. A phandle pointing to the DMA controller
- 2. Device signal number, the signal line for single and burst requests
- connected from the device to the DMA40 engine
- 3. The DMA request line number (only when 'use fixed channel' is set)
- 4. A 32bit mask specifying; mode, direction and endianness
- [NB: This list will grow]
- 0x00000001: Mode:
- Logical channel when unset
- Physical channel when set
- 0x00000002: Direction:
- Memory to Device when unset
- Device to Memory when set
- 0x00000004: Endianness:
- Little endian when unset
- Big endian when set
- 0x00000008: Use fixed channel:
- Use automatic channel selection when unset
- Use DMA request line number when set
- 0x00000010: Set channel as high priority:
- Normal priority when unset
- High priority when set
-
-Existing signal numbers for the DB8500 ASIC. Unless specified, the signals are
