1FLCTL NAND controller
2
3Required properties:
4- compatible : "renesas,shmobile-flctl-sh7372"
5- reg : Address range of the FLCTL
6- interrupts : flste IRQ number
7- nand-bus-width : bus width to NAND chip
8
9Optional properties:
10- dmas: DMA specifier(s)
11- dma-names: name for each DMA specifier. Valid names are
12	     "data_tx", "data_rx", "ecc_tx", "ecc_rx"
13
14The DMA fields are not used yet in the driver but are listed here for
15completing the bindings.
16
17The device tree may optionally contain sub-nodes describing partitions of the
18address space. See mtd.yaml for more detail.

21
22	flctl@e6a30000 {
23		#address-cells = <1>;
24		#size-cells = <1>;
25		compatible = "renesas,shmobile-flctl-sh7372";
26		reg = <0xe6a30000 0x100>;
27		interrupts = <0x0d80>;
28
29		nand-bus-width = <16>;
30
31		dmas = <&dmac 1 /* data_tx */
32			&dmac 2;> /* data_rx */
33		dma-names = "data_tx", "data_rx";
34
35		system@0 {
36			label = "system";
37			reg = <0x0 0x8000000>;
38		};
39
40		userdata@8000000 {
41			label = "userdata";
42			reg = <0x8000000 0x10000000>;

44
45		cache@18000000 {
46			label = "cache";
47			reg = <0x18000000 0x8000000>;
48		};
