-* Renesas R-Car (RZ/G) DMA Controller Device Tree bindings
-
-Renesas R-Car (Gen 2/3) and RZ/G SoCs have multiple multi-channel DMA
-controller instances named DMAC capable of serving multiple clients. Channels
-can be dedicated to specific clients or shared between a large number of
-clients.
-
-Each DMA client is connected to one dedicated port of the DMAC, identified by
-an 8-bit port number called the MID/RID. A DMA controller can thus serve up to
-256 clients in total. When the number of hardware channels is lower than the
-number of clients to be served, channels must be shared between multiple DMA
-clients. The association of DMA clients to DMAC channels is fully dynamic and
-not described in these device tree bindings.
-
-Required Properties:
-
-- compatible: "renesas,dmac-<soctype>", "renesas,rcar-dmac" as fallback.
-	      Examples with soctypes are:
-		- "renesas,dmac-r8a7743" (RZ/G1M)
-		- "renesas,dmac-r8a7744" (RZ/G1N)

-		- "renesas,dmac-r8a77970" (R-Car V3M)

-		- "renesas,dmac-r8a77990" (R-Car E3)
-		- "renesas,dmac-r8a77995" (R-Car D3)
-
-- reg: base address and length of the registers block for the DMAC
-
-- interrupts: interrupt specifiers for the DMAC, one for each entry in
-  interrupt-names.
-- interrupt-names: one entry for the error interrupt, named "error", plus one
-  entry per channel, named "ch%u", where %u is the channel number ranging from
-  zero to the number of channels minus one.
-
-- clock-names: "fck" for the functional clock
-- clocks: a list of phandle + clock-specifier pairs, one for each entry
-  in clock-names.
-- clock-names: must contain "fck" for the functional clock.
-
-- #dma-cells: must be <1>, the cell specifies the MID/RID of the DMAC port
-  connected to the DMA client
-- dma-channels: number of DMA channels
