1IFM camera sensor interface on mpc5200 LocalPlus bus 2 3Required properties: 4- compatible: "ifm,o2d-csi" 5- reg: specifies sensor chip select number and associated address range 6- interrupts: external interrupt line number and interrupt sense mode 7 of the interrupt line signaling frame valid events 8- gpios: three gpio-specifiers for "capture", "reset" and "master enable" 9 GPIOs (strictly in this order). 10- ifm,csi-clk-handle: the phandle to a node in the DT describing the sensor 11 clock generator. This node is usually a general purpose timer controller. 12- ifm,csi-addr-bus-width: address bus width (valid values are 16, 24, 25) 13- ifm,csi-data-bus-width: data bus width (valid values are 8 and 16) 14- ifm,csi-wait-cycles: sensor bus wait cycles 15 16Optional properties: 17- ifm,csi-byte-swap: if this property is present, the byte swapping on 18 the bus will be enabled. 19 20Example: 21 22 csi@3,0 { 23 compatible = "ifm,o2d-csi"; 24 reg = <3 0 0x00100000>; /* CS 3, 1 MiB range */ 25 interrupts = <1 1 2>; /* IRQ1, edge falling */ 26 27 ifm,csi-clk-handle = <&timer7>; 28 gpios = <&gpio_simple 23 0 /* image_capture */ 29 &gpio_simple 26 0 /* image_reset */ 30 &gpio_simple 29 0>; /* image_master_en */ 31 32 ifm,csi-addr-bus-width = <24>; 33 ifm,csi-data-bus-width = <8>; 34 ifm,csi-wait-cycles = <0>; 35 }; 36 37The base address of the used chip select is specified in the 38ranges property of the parent localbus node, for example: 39 40 ranges = <0 0 0xff000000 0x01000000 41 3 0 0xe3000000 0x00100000>; 42
