It provides full-frame, 16 sub-sampled, and windowed 10-bit MIPI images in various formats via the 17 Serial Camera Control Bus (SCCB) interface. This chip is programmable 18 through I2C and two-wire SCCB. The sensor output is available via CSI-2 19 serial data output (up to 4-lane). 20 21properties: 22 compatible: 23 const: ovti,ov8856 24 25 reg: 26 maxItems: 1 27 28 clocks: 29 maxItems: 1 30 31 clock-names: 32 description: 33 Input clock for the sensor. 34 items: 35 - const: xvclk 36 37 clock-frequency: 38 description: 39 Frequency of the xvclk clock in Hertz. 40 41 dovdd-supply: 42 description: 43 Definition of the regulator used as interface power supply. 44 45 avdd-supply: 46 description: 47 Definition of the regulator used as analog power supply. 48 49 dvdd-supply: 50 description: 51 Definition of the regulator used as digital power supply. 52 53 reset-gpios: 54 description: 55 The phandle and specifier for the GPIO that controls sensor reset. 56 This corresponds to the hardware pin XSHUTDOWN which is physically 57 active low. 58 59 port: 60 $ref: /schemas/graph.yaml#/$defs/port-base 61 additionalProperties: false 62 63 properties: 64 endpoint: 65 $ref: /schemas/media/video-interfaces.yaml# 66 unevaluatedProperties: false 67 68 properties: 69 data-lanes: 70 description: |- 71 The driver only supports four-lane operation. 72 items: 73 - const: 1 74 - const: 2 75 - const: 3 76 - const: 4 77 78 link-frequencies: 79 description: Frequencies listed are driver, not h/w limitations. 80 maxItems: 2 81 items: 82 enum: [ 360000000, 180000000 ] 83 84 required: 85 - link-frequencies 86 87required: 88 - compatible 89 - reg 90 - clocks 91 - clock-names 92 - clock-frequency 93 - dovdd-supply 94 - avdd-supply 95 - dvdd-supply 96 - reset-gpios 97 - port 98 99additionalProperties: false 100 101examples: 102 - | 103 #include <dt-bindings/gpio/gpio.h> 104 105 i2c { 106 #address-cells = <1>; 107 #size-cells = <0>; 108 109 ov8856: camera@10 { 110 compatible = "ovti,ov8856"; 111 reg = <0x10>; 112 113 reset-gpios = <&pio 111 GPIO_ACTIVE_LOW>; 114 pinctrl-names = "default"; 115 pinctrl-0 = <&clk_24m_cam>; 116 117 clocks = <&cam_osc>; 118 clock-names = "xvclk"; 119 clock-frequency = <19200000>; 120 121 avdd-supply = <&mt6358_vcama2_reg>; 122 dvdd-supply = <&mt6358_vcamd_reg>; 123 dovdd-supply = <&mt6358_vcamio_reg>; 124 125 port { 126 wcam_out: endpoint { 127 remote-endpoint = <&mipi_in_wcam>; 128 data-lanes = <1 2 3 4>; 129 link-frequencies = /bits/ 64 <360000000>; 130 }; 131 }; 132 }; 133 }; 134...
