Hello, I could not make Silead MSSL1680 touchscreen work on VOYO VBook A1 laptop, with all 4.11.* kernels, distro openSUSE 42.2. I have not tried kernels 4.12-rc* yet. Default openSUSE 42.2 kernel 4.4.62 had the same issue (timeout).

I can not try 4.12-rc* kernels currently because they don't have the Secure Boot signature by openSUSE maintainers yet and I did not succeed in signing them manually. The BIOS of this laptop requires the Secure Boot to be enabled to boot Linux so I can't just disable it to run the unsigned kernels.
