Port mapping for D3 camera ov5640 in DTS file

[vinay2010singh]

Hello ,

I have enabled D3 camera (in low speed mezzanine) (ov5640) on i2c2 node
I have also created it dts node as…

/*

• This dtsi file is for x2 lane D3 CAMERA for JETCARRIER96
• 7000c500.i2c : i2c2 , address i2c2@0x77
  /
  #include"JC96-plugin-manager.dtsi"
  /{
  //ov5640_mipi: ov5640_mipi@3d {
  i2c@7000c500{
  compatible = “ovti,ov5640_mipi”;
  //reg = <0x3d>;
  reg = <0x77>;
  status = “okay”;
  pinctrl-names = “default”;
  pinctrl-0 = <&pinctrl_csi1_pwn>;
  clocks = <&clk IMX8MQ_CLK_CLKO2>;
  clock-names = “csi_mclk”;
  assigned-clocks = <&clk IMX8MQ_CLK_CLKO2>,
  <&clk IMX8MQ_CLK_CLKO2>;
  assigned-clock-parents = <&clk IMX8MQ_SYS2_PLL_200M>;
  assigned-clock-rates = <0>, <20000000>;
  csi_id = <0>;
  pwn-gpios = <&gpio1 3 GPIO_ACTIVE_HIGH>;
  ** rst-gpios = <&gpio3 12 GPIO_ACTIVE_LOW>;*
  mclk = <20000000>;
  mclk_source = <0>;
  port {
  ov5640_mipi1_ep: endpoint {
  remote-endpoint = <&mipi1_sensor_ep>;
  };
  };
  }
  };

but i am doubtful about gpio mapping for power (pwn-gpio) and reset(rst-gpios)…

pwn-gpios = <&gpio1 3 GPIO_ACTIVE_HIGH>;
rst-gpios = <&gpio3 12 GPIO_ACTIVE_LOW>;

hello vinay2010singh,

please access Jetson Xavier NX Product Design Guide,
you should also check [Table 9-2. Jetson Xavier NX Camera Miscellaneous Pin Descriptions] for general used GPIO pins,
thanks
