0001 IFM camera sensor interface on mpc5200 LocalPlus bus
0002 
0003 Required properties:
0004 - compatible: "ifm,o2d-csi"
0005 - reg: specifies sensor chip select number and associated address range
0006 - interrupts: external interrupt line number and interrupt sense mode
0007   of the interrupt line signaling frame valid events
0008 - gpios: three gpio-specifiers for "capture", "reset" and "master enable"
0009   GPIOs (strictly in this order).
0010 - ifm,csi-clk-handle: the phandle to a node in the DT describing the sensor
0011   clock generator. This node is usually a general purpose timer controller.
0012 - ifm,csi-addr-bus-width: address bus width (valid values are 16, 24, 25)
0013 - ifm,csi-data-bus-width: data bus width (valid values are 8 and 16)
0014 - ifm,csi-wait-cycles: sensor bus wait cycles
0015 
0016 Optional properties:
0017 - ifm,csi-byte-swap: if this property is present, the byte swapping on
0018   the bus will be enabled.
0019 
0020 Example:
0021 
0022         csi@3,0 {
0023                 compatible = "ifm,o2d-csi";
0024                 reg = <3 0 0x00100000>;         /* CS 3, 1 MiB range */
0025                 interrupts = <1 1 2>;           /* IRQ1, edge falling */
0026 
0027                 ifm,csi-clk-handle = <&timer7>;
0028                 gpios = <&gpio_simple 23 0      /* image_capture */
0029                          &gpio_simple 26 0      /* image_reset */
0030                          &gpio_simple 29 0>;    /* image_master_en */
0031 
0032                 ifm,csi-addr-bus-width = <24>;
0033                 ifm,csi-data-bus-width = <8>;
0034                 ifm,csi-wait-cycles = <0>;
0035         };
0036 
0037 The base address of the used chip select is specified in the
0038 ranges property of the parent localbus node, for example:
0039 
0040         ranges = <0 0 0xff000000 0x01000000
0041                   3 0 0xe3000000 0x00100000>;
