It provides full-frame,16 sub-sampled, and windowed 10-bit MIPI images in various formats via the17 Serial Camera Control Bus (SCCB) interface. This chip is programmable18 through I2C and two-wire SCCB. The sensor output is available via CSI-219 serial data output (up to 4-lane).20 21properties:22 compatible:23 const: ovti,ov885624 25 reg:26 maxItems: 127 28 clocks:29 maxItems: 130 31 clock-names:32 description:33 Input clock for the sensor.34 items:35 - const: xvclk36 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 physically57 active low.58 59 port:60 $ref: /schemas/graph.yaml#/$defs/port-base61 additionalProperties: false62 63 properties:64 endpoint:65 $ref: /schemas/media/video-interfaces.yaml#66 unevaluatedProperties: false67 68 properties:69 data-lanes:70 oneOf:71 - items:72 - const: 173 - items:74 - const: 175 - const: 276 - items:77 - const: 178 - const: 279 - const: 380 - const: 481 82 required:83 - link-frequencies84 85required:86 - compatible87 - reg88 - clocks89 - clock-names90 - clock-frequency91 - dovdd-supply92 - avdd-supply93 - dvdd-supply94 - reset-gpios95 - port96 97additionalProperties: false98 99examples:100 - |101 #include <dt-bindings/gpio/gpio.h>102 103 i2c {104 #address-cells = <1>;105 #size-cells = <0>;106 107 ov8856: camera@10 {108 compatible = "ovti,ov8856";109 reg = <0x10>;110 111 reset-gpios = <&pio 111 GPIO_ACTIVE_LOW>;112 pinctrl-names = "default";113 pinctrl-0 = <&clk_24m_cam>;114 115 clocks = <&cam_osc>;116 clock-names = "xvclk";117 clock-frequency = <19200000>;118 119 avdd-supply = <&mt6358_vcama2_reg>;120 dvdd-supply = <&mt6358_vcamd_reg>;121 dovdd-supply = <&mt6358_vcamio_reg>;122 123 port {124 wcam_out: endpoint {125 remote-endpoint = <&mipi_in_wcam>;126 data-lanes = <1 2 3 4>;127 link-frequencies = /bits/ 64 <360000000>;128 };129 };130 };131 };132...133
