mipi camera怎么在rk平台的dts上做适配？

RTC观主 • 来源： 飞一样的成长 • • 技术文章

之前有很多朋友问在rk平台上怎么适配mipi摄像头，或者说在设备树里面去修改，今天分享一篇不错的文章给大家！

MIPI-CSI

RK3588s MIPI-CSI资源介绍：

注意：D/C-PHY 仅用作DPHY-V2.0。

VICAP

RK3588/RK3588S VICAP支持输入输出规格：

ISP

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

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。

mipi camera怎么在rk平台的dts上做适配？

框图说明：

  • 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。
  • 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。

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） 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。

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。

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。

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。

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:

 红外滤光片（IRCUT）由两根线控制，对这两根线施加3.5v~6v的电源，通过对IRCUT供电电源的正负极对调，且满足通电时间100ms±10%，能够实现IRCUT的切换。驱动通过两个gpio控制电机驱动器的电流输出方向，gpio命令为open（红线）、close（黑线）。电流由open流向close，为红外截止滤光片，白天工作状态；电流由close流向open，为白玻璃片，夜晚工作状态。其配置如下：
