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>;
