techpoint 2815/2855四通道图像解码芯片，通过MIPI CSI接口和主控连接,我的设备树配置如下，但是目前摄像头还没有调试成功，可以帮我看一下设备树配置吗？在dtsi配置了isp和ispp链路图像也无法进入ISP。2815没有ISP, 但是模拟传输的架构下ISP在camera端，2815接收到的已经是ISP处理过的数据，不需要SOC的ISP，我在rk3588使用图像解码芯片techpoint tp2855外接四个摄像头，我的设备树配置如下，但是目前摄像头还没有调试成功，可以帮我看一下设备树配置吗？驱动使用的代码是这个链接;https://github.com/armbian/linux-rockchip/tree/rk-5.10-rkr4/drivers/media/i2c/techpoint，还是使用sdk目录下drivers/media/i2c/tp2855.c自带的驱动
