1Atmel Image Sensor Interface (ISI) SoC Camera Subsystem 2---------------------------------------------- 3 4Required properties: 5- compatible: must be "atmel,at91sam9g45-isi" 6- reg: physical base address and length of the registers set for the device; 7- interrupts: should contain IRQ line for the ISI; 8- clocks: list of clock specifiers, corresponding to entries in 9 the clock-names property; 10- clock-names: must contain "isi_clk", which is the isi peripherial clock. 11 12ISI supports a single port node with parallel bus. It should contain one 13'port' child node with child 'endpoint' node. Please refer to the bindings 14defined in Documentation/devicetree/bindings/media/video-interfaces.txt. 15 16Example: 17 isi: isi@f0034000 { 18 compatible = "atmel,at91sam9g45-isi"; 19 reg = <0xf0034000 0x4000>; 20 interrupts = <37 IRQ_TYPE_LEVEL_HIGH 5>; 21 22 clocks = <&isi_clk>; 23 clock-names = "isi_clk"; 24 25 pinctrl-names = "default"; 26 pinctrl-0 = <&pinctrl_isi>; 27 28 port { 29 #address-cells = <1>; 30 #size-cells = <0>; 31 32 isi_0: endpoint { 33 remote-endpoint = <&ov2640_0>; 34 bus-width = <8>; 35 }; 36 }; 37 }; 38 39 i2c1: i2c@f0018000 { 40 ov2640: camera@0x30 { 41 compatible = "ovti,ov2640"; 42 reg = <0x30>; 43 44 port { 45 ov2640_0: endpoint { 46 remote-endpoint = <&isi_0>; 47 bus-width = <8>; 48 }; 49 }; 50 }; 51 }; 52
