Tool/software:
Hi, We are testing GMSL and gstreamer is hung waiting on data.
I can see data clocking on DCLK, D0, D1, D2, and D3, but I checked register 0x30122010 and it says all streams are idle.
I have it set up nearly identical to the v3link demo, so I think there is some other driver-level problem.
The parent ticket had a similar problem at first, but I'm using the maxim,max96716a driver, which already enables the stream only in max96716_enable_streams, so I don't think I can apply the same fix.
Are there known issues that might prevent the data from getting clocked inside the csi2rx driver?
What other registers should I be checking?
I noticed there is a "lane-polarity" option that I have not used. (All positive and negative pins are connected straight through, so I don't think I need to invert them)
I also noticed there are test pattern options I could enable which might reduce the complexity of the issue, but those do not clock data either.

I got it to connect once by changing the clock polarity, but it doesn't consistently connect.
