ISP

RK3588/RK3588s 的ISP属于RK ISP v3.0版本，拥有2个ISP。

注：CIS全称CMOS Image Sensor

RK3588 Camera相关 DTS配置介绍

这里以RK3588-EVB开发板的camera配置来进行说明

RK3588 的camera通路

下图是RK3588 camera连接链路示意图，可以支持7路camera。

框图说明：

1. rk3588支持两个dcphy，节点名称分别为csi2_dcphy0/csi2_dcphy1。每个dcphy硬件支持RX/TX同时使用，对于camera输入使用的是RX。支持DPHY/CPHY协议复用；需要注意的是同一个dcphy的TX/RX只能同时使用DPHY或同时使用CPHY。其他dcphy参数请查阅rk3588数据手册。
2. rk3588支持2个dphy硬件，这里我们称之为dphy0_hw/dphy1_hw，两个dphy硬件都可以工作在full mode 和split mode两种模式下。
   dphy0_hw:

• full mode：节点名称使用csi2_dphy0，最多支持4 lane。
• split mode： 拆分成2个phy使用，分别为csi2_dphy1（使用0/1 lane）、csi2_dphy2(使用2/3 lane)，每个phy最多支持2 lane。
• 当dphy0_hw使用full mode时，链路需要按照csi2_dphy1这条链路来配置，但是节点名称csi2_dphy1需要修改为csi2_dphy0，软件上是通过phy的序号来区分phy使用的模式。
  dphy1_hw:
• full mode：节点名称使用csi2_dphy3，最多支持4 lane。
• split mode： 拆分成2个phy使用，分别为csi2_dphy4（使用0/1 lane）、csi2_dphy5(使用2/3 lane)，每个phy最多支持2 lane。
• 当dphy1_hw使用full mode时，链路需要按照csi2_dphy4这条链路来配置，但是节点名称csi2_dphy4需要修改为csi2_dphy3，软件上是通过phy的序号来区分phy使用的模式。

3. 使用上述mipi phy节点，需要把对应的物理节点配置上。
   （csi2_dcphy0_hw/csi2_dcphy1_hw/csi2_dphy0_hw/csi2_dphy1_hw）
4. 每个mipi phy都需要一个csi2模块来解析mipi协议，节点名称分别为mipi0_csi2~mipi5_csi2。
5. rk3588所有camera数据都需要通过vicap，再链接到isp。rk3588仅支持一个vicap硬件，这个vicap支持同时输入6路mipi phy，及一路dvp数据，所以我们将vicap分化成rkcif_mipi_lvds~rkcif_mipi_lvds5、rkcif_dvp等7个节点，各个节点的绑定关系需要严格按照框图的节点序号配置。
6. 每个vicap节点与isp的链接关系，通过对应虚拟出的XXX_sditf来指明链接关系。
7. rk3588支持2个isp硬件，每个isp设备可虚拟出多个虚拟节点，软件上通过回读的方式，依次从ddr读取每一路的图像数据进isp处理。对于多摄方案，建议将数据流平均分配到两个isp上。
8. 直通与回读模式：

• 直通：指数据经过vicap采集，直接发送给isp处理，不存储到ddr。需要注意的是hdr直通时，只有短帧是真正的直通，长帧需要存在ddr，isp再从ddr读取。
• 回读：指数据经过vicap采集到ddr，应用获取到数据后，将buffer地址推送给isp，isp再从ddr获取图像数据。
• 再dts配置时，一个isp硬件，如果只配置一个虚拟节点，默认使用直通模式，如果配置了多个虚拟节点默认使用回读模式。

单路Camera的dts配置说明

RK3588 EVB开发板默认只有1路camera，其链接方式如上图的mipi camera0。DTS配置在kernel-5.10\arch\arm64\boot\dts\rockchip\rk3588-evb1-imx415.dtsi，可以结合上的图来理解这个dts的配置，如下
