Background: I would like to capture IMX477's HDR(long/short ex)raw in raspi 4.
Status:
1. I already configure the regestier settings in IMX477 driver(IMX477.c) to enable its 2DoL HDR mode.
2. I comfirmed that IMX477's framestructure, that it use Virtual Channel 0/1 to manage long/short frames.
3. I also find that in unciam driver(bcm2835-unicam.c) that only support VC0

I am trying if i can enable unciam's VC 1 and make it possible to caputre long/short frame raw.
But I am a beginner of driver development, not sure what kind of changes should do for unciam(may not only for uncaim, but also some others change are also need).
And what I finnally want to achieve is below
