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.
下面深圳视壮给大家简单说明，更多详看 bbs.videostrong.com
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 = ;
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
