VS-RK3399 板卡上Debian系统，摄像头OV13850模块处理方式

debian系统目前支持Usb camera是没有问题，走UVC功能接口。那么mipi 接口camera和并口接口的camera，在Debian系统怎么设置呢，其实原理一样，也走uvc接口封装函数.

下面给他大家简单说明：
首先在dts文件定义Mipi camera接口的定义：
camera0: camera-module@60 {
      status = "okay";
      compatible = "ovti,ov13850-v4l2-i2c-subdev";
      reg = < 0x60 >;
      device_type = "v4l2-i2c-subdev";
      clocks = <&cru SCLK_CIF_OUT>;
      clock-names = "clk_cif_out";
      pinctrl-names = "rockchip,camera_default",
         "rockchip,camera_sleep";
      pinctrl-0 = <&cam0_default_pins>;
      pinctrl-1 = <&cam0_sleep_pins>;

      rockchip,pwr-gpio = <&gpio2 10 GPIO_ACTIVE_HIGH>;
      rockchip,camera-module-mclk-name = "clk_cif_out";
      rockchip,camera-module-facing = "back";
      rockchip,camera-module-name = "cmk-cb0695-fv1";
      rockchip,camera-module-len-name = "lg9569a2";
      rockchip,camera-module-fov-h = "133.0";
      rockchip,camera-module-fov-v = "100.1";
      rockchip,camera-module-orientation = <0>;
      rockchip,camera-module-iq-flip = <0>;
      rockchip,camera-module-iq-mirror = <0>;
      rockchip,camera-module-flip = <0>;
      rockchip,camera-module-mirror = <0>;
      rockchip,camera-module-defrect0 = <640 480 0 0 640 480>;
      rockchip,camera-module-defrect1 = <640 480 0 0 640 480>;
      rockchip,camera-module-defrect2 = <640 480 0 0 640 480>;
      rockchip,camera-module-defrect3 = <640 480 0 0 640 480>;
      rockchip,camera-module-flash-support = <0>;
      rockchip,camera-module-mipi-dphy-index = <0>;
};

cif_isp0: cif_isp@ff910000 {
      compatible = "rockchip,rk3399-cif-isp";
      rockchip,grf = <&grf>;
      reg = <0x0 0xff910000 0x0 0x4000>, <0x0 0xff968000 0x0 0x8000>;
      reg-names = "register", "dsihost-register";
      clocks =
         <&cru ACLK_ISP0_NOC>, <&cru ACLK_ISP0_WRAPPER>,
         <&cru HCLK_ISP0_NOC>, <&cru HCLK_ISP0_WRAPPER>,
         <&cru SCLK_ISP0>, <&cru SCLK_DPHY_RX0_CFG>,
         <&cru SCLK_CIF_OUT>, <&cru SCLK_CIF_OUT>,
         <&cru SCLK_MIPIDPHY_REF>;
      clock-names =
         "aclk_isp0_noc", "aclk_isp0_wrapper",
         "hclk_isp0_noc", "hclk_isp0_wrapper",
         "clk_isp0", "pclk_dphyrx",
         "clk_cif_out", "clk_cif_pll",
         "pclk_dphy_ref";
      interrupts = <GIC_SPI 43 IRQ_TYPE_LEVEL_HIGH 0>;
      interrupt-names = "cif_isp10_irq";
      power-domains = <&power RK3399_PD_ISP0>;
      rockchip,isp,iommu-enable = <1>;
      iommus = <&isp0_mmu>;
      status = "disabled";
};
通过上面的配置后，打开驱动，驱动加载成功了。通过应用就可以切换摄像头，图像就可以出来了
