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: Tested-by: Sebastian Fricke <sebastian.fricke@xxxxxxxxxx> On 02.02.2021 15:56, Heiko Stuebner wrote:
The rk3399 has two ISPs and right now only the first one is usable. The second ISP is connected to the TXRX dphy on the soc. The phy of ISP1 is only accessible through the DSI controller's io-memory, so this series adds support for simply using the dsi controller is a phy if needed. That solution is needed at least on rk3399 and rk3288 but no-one has looked at camera support on rk3288 at all, so right now only implement the rk3399 specifics.
