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>;
