Hello, this series is a followup to the other series [1] started by Niklas Söderlund where only the first patch has been merged. The overall idea is to be more compliant with the Renesas hardware manual which requires a reset or stop of capture in the VIN module before reset of CSI2. Another goal is to be more resilient with respect to non-critical CSI2 errors so the driver does not end in an endless restart loop. Compared to the previous version [2] of this series the patch 3 is replaced based on the conclusion in [3] so now userspace has to take care of figuring out if a transfer error was harmless or unrecoverable. Other patches are adapted accordingly so no assumptions about criticality of transfer errors are made in the kernel and the decision is left up to userspace.
