7- compatible:	must be one of
8		"renesas,nbpfaxi64dmac1b4"
9		"renesas,nbpfaxi64dmac1b8"
10		"renesas,nbpfaxi64dmac1b16"
11		"renesas,nbpfaxi64dmac4b4"
12		"renesas,nbpfaxi64dmac4b8"
13		"renesas,nbpfaxi64dmac4b16"
14		"renesas,nbpfaxi64dmac8b4"
15		"renesas,nbpfaxi64dmac8b8"
16		"renesas,nbpfaxi64dmac8b16"
17- #dma-cells:	must be 2: the first integer is a terminal number, to which this
18		slave is connected, the second one is flags. Flags is a bitmask
19		with the following bits defined:
20
21#define NBPF_SLAVE_RQ_HIGH	1
22#define NBPF_SLAVE_RQ_LOW	2
23#define NBPF_SLAVE_RQ_LEVEL	4
24
25Optional properties:
26
27You can use dma-channels and dma-requests as described in dma.txt, although they
28won't be used, this information is derived from the compatibility string.

30Example:
31
32	dma: dma-controller@48000000 {
33		compatible = "renesas,nbpfaxi64dmac8b4";

45		dma-requests = <8>;

52dmas and dma-names are required, as described in dma.txt.

59		dmas = <&dma 0 (NBPF_SLAVE_RQ_HIGH | NBPF_SLAVE_RQ_LEVEL)
