Support for capturing from cameras on IPU6 systems (IPU6 ISYS driver and IPU bridge changes) was upstreamed for 6.10, with some drivers such as IVSC (four of them) and IVSC related IPU bridge changes merged for 6.8 already. We can't guarantee the continued functioning of downstream drivers in cases where new upstream drivers for the same devices get merged to the kernel, often with different APIs. You know that as well as I do. In other words, there was no regression with respect to the upstream kernel. -- Kind regards, Sakari Ailus
