| 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>; |
