Hi guys,

I am playing with Hikey and I am able to get wifi up and running on 3.18 Linaro kernel base/hikey branch. But I am not able to get it work on 4.4 or mainline. The problem is that st_tty_open is not called that's why it looks like that problem could be with line discipline setup.

Do you have any kernel/branch with 4.4+ where BT is working?

Thanks, Michal
