-Texas Instruments eDMA
-
-The eDMA3 consists of two components: Channel controller (CC) and Transfer
-Controller(s) (TC). The CC is the main entry for DMA users since it is
-responsible for the DMA channel handling, while the TCs are responsible to
-execute the actual DMA tansfer.
-
-------------------------------------------------------------------------------
-eDMA3 Channel Controller
-
-Required properties:
---------------------
-- compatible: Should be:
- - "ti,edma3-tpcc" for the channel controller(s) on OMAP,
- AM33xx and AM43xx SoCs.
- - "ti,k2g-edma3-tpcc", "ti,edma3-tpcc" for the
- channel controller(s) on 66AK2G.
-- #dma-cells: Should be set to <2>. The first number is the DMA request
- number and the second is the TC the channel is serviced on.
-- reg: Memory map of eDMA CC
-- reg-names: "edma3_cc"
-- interrupts: Interrupt lines for CCINT, MPERR and CCERRINT.
-- interrupt-names: "edma3_ccint", "edma3_mperr" and "edma3_ccerrint"
-- ti,tptcs: List of TPTCs associated with the eDMA in the following form:
- <&tptc_phandle TC_priority_number>. The highest priority is 0.
-
-SoC-specific Required properties:
---------------------------------
-The following are mandatory properties for OMAP, AM33xx and AM43xx SoCs only:
-- ti,hwmods: Name of the hwmods associated to the eDMA CC.
-
-The following are mandatory properties for 66AK2G SoCs only:
-- power-domains:Should contain a phandle to a PM domain provider node
- and an args specifier containing the device id
- value. This property is as per the binding,
- Documentation/devicetree/bindings/soc/ti/sci-pm-domain.yaml
-
-Optional properties:
--------------------
-- ti,edma-memcpy-channels: List of channels allocated to be used for memcpy, iow
- these channels will be SW triggered channels. See example.
-- ti,edma-reserved-slot-ranges: PaRAM slot ranges which should not be used by
- the driver, they are allocated to be used by for example the
- DSP. See example.
-- dma-channel-mask: Mask of usable channels.
- Single uint32 for EDMA with 32 channels, array of two uint32 for
- EDMA with 64 channels. See example and
- Documentation/devicetree/bindings/dma/dma-common.yaml
-
-
-------------------------------------------------------------------------------
-eDMA3 Transfer Controller
-
-Required properties:
---------------------
-- compatible: Should be:
- - "ti,edma3-tptc" for the transfer controller(s) on OMAP,
- AM33xx and AM43xx SoCs.
- - "ti,k2g-edma3-tptc", "ti,edma3-tptc" for the
- transfer controller(s) on 66AK2G.
-- reg: Memory map of eDMA TC
-- interrupts: Interrupt number for TCerrint.

-DEPRECATED binding, new DTS files must use the ti,edma3-tpcc/ti,edma3-tptc
-binding.
-
-Required properties:
-- compatible : "ti,edma3"
-- #dma-cells: Should be set to <1>
- Clients should use a single channel number per DMA request.
-- reg: Memory map for accessing module
-- interrupts: Exactly 3 interrupts need to be specified in the order:
- 1. Transfer completion interrupt.
- 2. Memory protection interrupt.
- 3. Error interrupt.
-Optional properties:
-- ti,hwmods: Name of the hwmods associated to the EDMA
-- ti,edma-xbar-event-map: Crossbar event to channel map
-
-Deprecated properties:
-Listed here in case one wants to boot an old kernel with new DTB. These
-properties might need to be added to the new DTS files.
-- ti,edma-regions: Number of regions
-- ti,edma-slots: Number of slots
-- dma-channels: Specify total DMA channels per CC
-
-Example:
-
-edma: edma@49000000 {
- reg = <0x49000000 0x10000>;
- interrupt-parent = <&intc>;
