debian系統目前支持Usb camera是沒有問題，走UVC功能接口。那么mipi 接口camera和并口接口的camera，在Debian系統怎么設置呢，其實原理一樣，也走uvc接口封裝函數.

下面深圳視壯給大家簡單說明，更多詳看 bbs.videostrong.com

首先在dts文件定義Mipi camera接口的定義：

camera0: camera-module@60 {

status = "okay";

compatible = "ovti,ov13850-v4l2-i2c-subdev";

reg = < 0x60 >;

device_type = "v4l2-i2c-subdev";

clocks = ;

clock-names = "clk_cif_out";

pinctrl-names = "rockchip,camera_default",

"rockchip,camera_sleep";

pinctrl-0 = ;

pinctrl-1 = ;

rockchip,pwr-gpio = ;

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 = ;

reg = <0x0 0xff910000 0x0 0x4000>, <0x0 0xff968000 0x0 0x8000>;

reg-names = "register", "dsihost-register";

clocks =

, ,

, ,

, ,

, ,

;

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 = ;

interrupt-names = "cif_isp10_irq";

power-domains = ;

rockchip,isp,iommu-enable = <1>;

iommus = ;

status = "disabled";

};

通過上面的配置后，打開驅動，驅動加載成功了。通過應用就可以切換攝像頭，圖像就可以出來了
