      V853做的板子，buildroot系统，要适配一个gc2503 4land的单目摄像头,，看了文档都是双目的，弄了好久没有弄出图像来，不知道怎么搞了，求指导。以下是做过的操作：
      1、DTS的vind节点如下：

                    vind0:vind@0 {
			vind0_clk = <200000000>;
			status = "okay";

	                 csi2:csi@2 {
		              pinctrl-names = "default","sleep";
                              pinctrl-0 = <&ncsi_pins_a>;
                              pinctrl-1 = <&ncsi_pins_b>;
                              status = "disabled";
	                };

		/*offline mode*/
             tdm0:tdm@0 {
                 work_mode = <1>;
             };

             isp00:isp@0 {
                 work_mode = <1>;
             };

             scaler00:scaler@0 {
                 work_mode = <1>;
             };

             scaler10:scaler@4 {
                 work_mode = <1>;
             };

             scaler20:scaler@8 {
                 work_mode = <1>;
             };

             scaler30:scaler@12 {
                 work_mode = <1>;
             };

			}

      2、将模块放到板上insmod。可以出来/dev/video0节点

      Octops:/server/camera# ls
csi_test_mplane          v4l2_demo                videobuf2-v4l2.ko
da380.ko                 videobuf2-core.ko        vin_io.ko
gc2053_mipi.ko           videobuf2-dma-contig.ko  vin_v4l2.ko
ism.sh                   videobuf2-memops.ko
Octops:/server/camera#
Octops:/server/camera# cat ism.sh
insmod videobuf2-core.ko
insmod videobuf2-memops.ko
insmod videobuf2-dma-contig.ko
insmod videobuf2-v4l2.ko
insmod vin_io.ko
insmod gc2053_mipi.ko
insmod  vin_v4l2.ko
Octops:/server/camera# ./ism.sh
[   90.451429] [VIN_WARN]sensor_helper_probe: cannot get sensor0_cameravdd supply, setting it to NULL!
Octops:/server/camera#
Octops:/server/camera# ls -l /dev/video0
crw-rw----    1 root     video      81,   0 Jan  1 01:51 /dev/video0
Octops:/server/camera#

      3、执行csi_test_mplane如下：

      Octops:/server/camera# ./csi_test_mplane
open /dev/video0 fd = 3
resolution got from sensor = 640*480 num_planes = 3
VIDIOC_STREAMON ok
file length = 307200 76800 76800
file start = 0xb6eee000 0xb6edb000 0xb6ec8000
Got signal 11, exiting ...
[   36.265546] [VIN_ERR]scaler0 channel ID nember is lost!!!
Octops:/server/camera#
Octops:/server/camera#
Octops:/server/camera# ./csi_test_mplane 0 0 1920 1080 /server 1 20000 60 0
open /dev/video0 fd = 3
resolution got from sensor = 1920*1080 num_planes = 3
VIDIOC_STREAMON ok
Octops:/server/camera#
Octops:/server/camera# ./csi_test_mplane 0

please input the frame saving path......

please input the test mode: 0~3......

please input the test_cnt: >=1......
20
open /dev/video0 fd = 3
resolution got from sensor = 1920*1080 num_planes = 3
VIDIOC_STREAMON ok
[  107.543269] [VIN_ERR]scaler0 channel ID nember is lost!!!
VIDIOC_STREAMOFF ok
mode 1 test done at the 0 time!!
time cost 1.221462(s)

      4、i2cdetect测试，发现器件地址对不上

      Octops:/server/camera# i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- UU -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

      问题：
      1、想确认下，4land的摄像头，需要专门指定4land吗？怎么指定？
      2、出现了video设备是可以说明硬件通了，只需要做软件的调试吗？
      3、为什么器件地址会变为原来的一半？
      4、有什么办法可以实时预览摄像头吗？
