1	IFM camera sensor interface on mpc5200 LocalPlus bus
2	
3	Required properties:
4	- compatible: "ifm,o2d-csi"
5	- reg: specifies sensor chip select number and associated address range
6	- interrupts: external interrupt line number and interrupt sense mode
7	  of the interrupt line signaling frame valid events
8	- gpios: three gpio-specifiers for "capture", "reset" and "master enable"
9	  GPIOs (strictly in this order).
10	- ifm,csi-clk-handle: the phandle to a node in the DT describing the sensor
11	  clock generator. This node is usually a general purpose timer controller.
12	- ifm,csi-addr-bus-width: address bus width (valid values are 16, 24, 25)
13	- ifm,csi-data-bus-width: data bus width (valid values are 8 and 16)
14	- ifm,csi-wait-cycles: sensor bus wait cycles
15	
16	Optional properties:
17	- ifm,csi-byte-swap: if this property is present, the byte swapping on
18	  the bus will be enabled.
19	
20	Example:
21	
22		csi@3,0 {
23			compatible = "ifm,o2d-csi";
24			reg = <3 0 0x00100000>;		/* CS 3, 1 MiB range */
25			interrupts = <1 1 2>;		/* IRQ1, edge falling */
26	
27			ifm,csi-clk-handle = <&timer7>;
28			gpios = <&gpio_simple 23 0	/* image_capture */
29				 &gpio_simple 26 0	/* image_reset */
30				 &gpio_simple 29 0>;	/* image_master_en */
31	
32			ifm,csi-addr-bus-width = <24>;
33			ifm,csi-data-bus-width = <8>;
34			ifm,csi-wait-cycles = <0>;
35		};
36	
37	The base address of the used chip select is specified in the
38	ranges property of the parent localbus node, for example:
39	
40		ranges = <0 0 0xff000000 0x01000000
41			  3 0 0xe3000000 0x00100000>;
