dcphy: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。
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。
•在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。
