全志适配TP9930时csi&isp setup link failed

shuaige LV 6

在调试时出现CSI与ISP未能链接的情况，有没有人遇到过，帮忙看一下
应用程序测试
csi_test_usrptr 16 0 1280 720 /usr 4 10 25
csi_test_usrptr 17 0 1280 720 /usr 4 10 25
CSI 和 ISP 之间的链接时遇到问题

定位代码：bsp/drivers/vin/vin-video/vin_video.c

添加打印，确认isp和csi 都非空

media_entity_find_link函数的实现
kernel/linux-5.15/drivers/media/mc/mc-entity.c

设备树：
在T527平台中，parser(csi)个数为4 个（parser0/1/2/3），其中 parser3可配置为并口输入。所以作为 BT656/BT1120 输入的时候，csi_sel 只能选择 3，不能选择其他选项
