Kernel-3.10.0-957.el7_ifm-csi

IFM camera sensor interface on mpc5200 LocalPlus bus

Required properties:

• compatible: “ifm,o2d-csi”
• reg: specifies sensor chip select number and associated address range
• interrupts: external interrupt line number and interrupt sense mode
  of the interrupt line signaling frame valid events
• gpios: three gpio-specifiers for “capture”, “reset” and “master enable”
  GPIOs (strictly in this order).
• ifm,csi-clk-handle: the phandle to a node in the DT describing the sensor
  clock generator. This node is usually a general purpose timer controller.
• ifm,csi-addr-bus-width: address bus width (valid values are 16, 24, 25)
• ifm,csi-data-bus-width: data bus width (valid values are 8 and 16)
• ifm,csi-wait-cycles: sensor bus wait cycles

Optional properties:

• ifm,csi-byte-swap: if this property is present, the byte swapping on
  the bus will be enabled.

Example:

csi@3,0 {
    compatible = "ifm,o2d-csi";
    reg = <3 0 0x00100000>;        /* CS 3, 1 MiB range */
    interrupts = <1 1 2>;        /* IRQ1, edge falling */

    ifm,csi-clk-handle = <&timer7>;
    gpios = <&gpio_simple 23 0    /* image_capture */
         &gpio_simple 26 0    /* image_reset */
         &gpio_simple 29 0>;    /* image_master_en */

    ifm,csi-addr-bus-width = <24>;
    ifm,csi-data-bus-width = <8>;
    ifm,csi-wait-cycles = <0>;
};

The base address of the used chip select is specified in the
ranges property of the parent localbus node, for example:

ranges = <0 0 0xff000000 0x01000000
      3 0 0xe3000000 0x00100000>;
