So I assumed it would be probed and loaded. If that worked, then I hoped we should be able to use pwm-lpss in i915. But as I said, I could not test or debug anything with lack of device. I am sure that the pwm-crystalcove should be working once module load problem is solved (Try attached patch in this bug) Putting patch set attempting lpss related changes in i915 again in this bug for completeness. <a href="https://patchwork.freedesktop.org/patch/70286/">https://patchwork.freedesktop.org/patch/70286/</a> <a href="https://patchwork.freedesktop.org/patch/70287/">https://patchwork.freedesktop.org/patch/70287/</a> <a href="https://patchwork.freedesktop.org/patch/70288/">https://patchwork.freedesktop.org/patch/70288/</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
