Laurent, can you confirm this? > > Is there anything else that blocks this patch series? v4l-utils side issues: I'd have to apply my local bug fixes and submit the next version. Kernel side issues: There is a regression in the kernel related to FIMC-LITE and FIMC-IS-ISP entities. Effectively currently it is only possible to setup pipelines with S5C73M3 sensor to fimc.0.capture and fimc.1.capture entities. I would also have to rebase the patches for exynos4-is driver for avoiding failure on open when the device being opened has no connected sensor. -- Best Regards, Jacek Anaszewski
