* Renesas R-Car DMA Controller Device Tree bindings
-Renesas R-Car Generation 2 SoCs have have multiple multi-channel DMA
+Renesas R-Car Generation 2 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.
-DMA clients are connected to the DMAC ports referenced by an 8-bit identifier
-called MID/RID.
-
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
