（1）RK3562 camera资源

①RK3562 camera硬件框图

RK3562 camera 资源硬件如下所示，拥有2路DPHY，4路CSI HOST，一个vicap控制器，1个isp控制器。其中2路DPHY可以分解成4x2lane的模式工作。

这边需要注意的是，RK3562不支持DVP接口。

②MIPI-CSI资源

RK3562的MIPI-CSI资源如下：

	Type	MAX bandwidth	BUM	Mode
DPHY	DPHY-v1.2	2.5G/bps x 4lane	2	4lane or 2x2lane

RK3562有2个4lane的DPHY，DPHY可以拆分模式按照4个2lane进行工作，有4个CSI-HOST工作，总计可以接入4路MIPI camera。2lane最大带宽是5G。

③VICAP资源

④ISP资源

RK3562 的ISP属于RK ISP v3.2 lite版本，拥有1个ISP，最高处理13M30的数据量。

工作模式	吞吐率	最大分辨率	输入格式
单CIS	13M@30fps	4224x3136	VICAP: raw8/raw10/raw12

多路camera的应用时，只要总计吞吐率小于13M@30即可。

⑤最多支持camera数量

根据上述，RK3562有4个MIPI-CSI接口，最多可以支持4路2lane的camera。4路camera的连接框图如下所示：

（2）dts配置

根据上述，RK3562至多可以同时接入4路 2lane的MIPI摄像头，这边先配置场景的2路camera前后摄切换的场景，2路双摄或者4路同时的配置，下篇文章再介绍。

两路前后摄切换配置如下：
