前面介绍了RK3562有2路MIPI DPHY，4个MIPI CSI HOST，意味着最多的情况下，RK3562可以同时接入4个2lane的MIPI摄像头。这里介绍一下4路MIPI同时接入的时候，dts需要如何配置。
目录
（1）多摄连接框图
①2x4lane 双摄连接框图
当RK3562接入两个4lane的摄像头，对应的连接框图如下：
dts按照上图进行配置即可，需要注意的是当多摄同时接入isp的时候，ISP必须使用回读模式，也就是必须将aiq运行起来，因此驱动注册成功之后，可以先在RKCIF的节点抓数据流确定驱动是否正常，或者单摄的场景下确认是否正常。
② 4x2lane 四摄连接框图
当RK3562同时接入4个2lane的摄像头时，对应的连接框图如下：
硬件连接需要注意：两个DPHY采用split mode的分割模式。
（2）多摄DTS配置
①dts配置
这边主要介绍一下4路2lane的摄像头同时接入的场景下的dts配置，参考如下：

};②XML对应配置
xml需要配置4路，主要关键如下：
<Profiles cameraId="0" name="gc8034" moduleId="m00">
......
<aiq.multicamera value="true"/> <!-- true or false --><Profiles cameraId="0" name="gc8034" moduleId="m01">
......
<aiq.multicamera value="true"/> <!-- true or false --><Profiles cameraId="0" name="ov5695" moduleId="m02">
......
<aiq.multicamera value="true"/> <!-- true or false --><Profiles cameraId="0" name="ov5695" moduleId="m03">
......
<aiq.multicamera value="true"/> <!-- true or false -->③cameraHAL添加多路支持
cameraHAL默认只支持2路，需要添加多路的支持：
