problem). The fail was present before this patch series. The core problem there is that if there are multiple possible framesizes, then crop support is ambiguous: against which framesize do you crop? I see that dcmi_try_fmt() has a heuristic for that. We really need to fix this in the API, but this situation rarely occurs. So for now I don't think there is a need to fix the fail.

Thanks Hans, I've aligned both namings by updating querycap: @@ -1257,7 +1257,8 @@ static int dcmi_querycap(struct file *file, void *priv, strscpy(cap->driver, DRV_NAME, sizeof(cap->driver)); strscpy(cap->card, "STM32 Camera Memory Interface", sizeof(cap->card)); - strscpy(cap->bus_info, "platform:dcmi", sizeof(cap->bus_info)); + snprintf(cap->bus_info, sizeof(cap->bus_info), + "platform:%s", DRV_NAME); return 0; } so now both V4L2 and MC are returning "platform:stm32-dcmi". I'll push in v2. BR, Hugues.
