Hello,
Please, consider applying this series to openSUSE-42.2 branch. The following patch series is to enable RS485 support for BeagleBone Black (armv7l architecture).
When we moved from deprecated BeagleBone Black serial driver (ttyOx) to new one (ttySx) in master branch, TIOCSRS485 ioctl support in user-space disappeared due to this migration. The support has been brought back in 4.6 using new implementation. The following patches are taken from 4.6 linux kernel release:
Well, I really would like to avoid openSUSE-42.2 specific kernel patches. One of the important point in Leap is the sharing of the code base with SLE. And for 42.2, the kernel code is shared with SLE12-SP2. The difference is only the config. The code is very much same.
42.1 was an individual kernel because of the timing, but 42.2 is a different story.
That said, these should go through SLE12-SP2, if they are really mandatory. It's not only about this patchset, but any patches to 42.2 kernel in general.
Though, I'm not entirely sure which path would work most effectively. For any bugs, usually Bugzilla would be the best place.
Matwey, could you open a Bugzilla entry for tracking the bug and your patches? Then we can evaluate there and merge to SLE12-SP2 and openSUSE-42.2 branch. Also we can try to push to stable 4.4.x tree if appropriate.
Hello, Sorry for the delay with answer. I'll create the bugreport. Should I attach the patches as files or may just put link here? I think that this series does not fulfill kernel stable rules. From the formal point of view, it adds new feature. Issue in openSUSE that we have two mutual kernel modules for the same hardware (the modules can not been compiled or run together) and each module implements its own set of features, so I am trying to add the most required missed feature. I've started this series development in Nov 2015 based on 4.3, so this definitely worked on 4.3, not only on 4.6. -- With best regards, Matwey V. Kornilov.
