Re: [PATCH 0/6] Support second Image Signal Processor on rk3399

[Sebastian Fricke]

Hey Heiko,

I have tested your patch set on my nanoPC-T4, here is a complete log
with:
- relevant kernel log entries
- system information
- media ctl output
- sysfs entry information

https://paste.debian.net/1183874/

Additionally, to your patchset I have applied the following patches:
https://github.com/initBasti/Linux_kernel_media_tree_fork/commits/dual_cam_setup

And just to not cause confusion the `media_dev` entries come from this
unmerged series:
https://patchwork.kernel.org/project/linux-media/list/?series=426269

I have actually been able to stream with both of my cameras at the same
time using the libcamera cam command.
I would like to thank you a lot for making this possible.

If you like to you can add:
