前言
海思3559a的sdk例子是没有提供BT1120和BT656视频接入的，但实际上硬件是可以支持接入的。不过前提是只支持逐行方式输入，不支持隔行视频，如果想输入PAL制式的隔行视频，请先用芯片转成逐行再接入。不知道是官方手册有意无意的忽略还是太简单约定俗成，例程没有手册相关描述又非常模糊，这里给出SDK2.0.3.1版本的BT656输入调试笔记，输入由adv7280逐行给出
硬件部分：
Hi3559AV100 DEV 与 MIPI/SLVS/BT.1120/BT.656/BT601/DC 接口的绑定关系如下
说明不是所有的mipi都可以被当做cmos作采集复用的，相关电路原理图设计如下
通过《Hi3559AV100_PINOUT_CN》可以查看对应的引脚，发现没有对应的配置寄存器，推测这块不需要我们来配置寄存器的，那就应该是VI CMOS2和MIPI RX Port2/MIPI RX Port3共用引脚通过使能对应接口时钟来选择。
根据《Hi3559A╱C V100 ultra-HD Mobile Camera SoC 用户指南》中MIPI_RX频率配置寄存器（PERI_CRG65），要使能VI CMOS2时钟，应当把PERI_CRG65的bit[11:9]置为111
此处有两种修改方式，阅读加载驱动的脚本load3559av100_multicore，之前传感器类型我们都选择的imx477作为模板加载，直接传入bt656在2.0.3.1版本的SDK里是会报not support的错误，根据报错信息可以找到Hi3559AV100_SDK_V2.0.3.1/drv/interdrv/sysconfig路径下的sysconfig.c

}

return 0;
}
}
第一种方式
可见，传bt656在这里也仅仅是为了配置这个寄存器，那么我们直接传参后单独修改寄存器也是可以的，直接
devmem 0x12010104 32 0xCEBEDB
个人觉得，归根结底到底层的实现肯定都是通过配置寄存器解决的，只是海思在驱动或者应用层的某些函数上帮我们封装好了，所以这个看似粗暴的办法，在分析清楚实现原理后，也是可以使用的
第二种方式
第二种就是忽略掉parse_sensor_index的报错往下走，将coms_clock_config修改正确，官方的SDK包里这个配置是不正确的！！
修改为
static void coms_clock_config(int index)
{
if(0 == index)
{
reg_write32(0x5 << 15, 0x7 << 15, (unsigned long)reg_crg_base+0x0104);
}
else if(1 == index)
{
reg_write32(0x6 << 21, 0x7 << 21, (unsigned long)reg_crg_base+0x0104);
}
else if(2 == index)
{
reg_write32(0x7 << 9, 0x7 << 9, (unsigned long)reg_crg_base+0x0104);
}
}
重新编译sysconfig.ko即可，这个就不需要单独配置寄存器了

关于返回的dev的值
结合手册之前的描述，推断：结构体combo_dev_attr_t的devno不是VI DEV号，也不是MIPI RX设备号（这里也根本没使用MIPI接口），而是VI CMOS号，本案例使用的是Hi3559A的VI CMOS2，因此devno = 2所以对应这里也返回的是2。

加载ko文件时还是正常操作就可以
VI日志
这些改完后就可以看到正确的VI日志而不是一团空白了
作为软件部分可以确定一定以及肯定，已经全部修改完毕了。
再出不来图像就需要联合硬件工程师排查电源，时钟，复位，甚至接线等问题（并口线在高速时要求相对会严格一些），联合逻辑工程师排查图像是否逐行，时钟可以测量到但是性能是否满足要求，物理层是否有数据流通。涉及匹配的电阻
如果硬件确认无误后，结合当前的配置环境，可以在vi的日志上，查看中断的是否增长，图像有无丢失，帧率是否稳定，基本就可以确定vi调试OK了，后续vi绑定vpss，vpss在绑定venc参考venc的sample或者之前的rtsp拉流或者本地保存，就可以直接看到图像来进一步确定最后结果和成像质量了
