We are trying to get a piece of Google hardware which uses the rt5645 driver working correctly with newer kernels (currently one based on the latest v4.14 stable), and noticed that the following commit:
commit 6b5da66322c5 ("ASoC: rt5645: read jd1_1 status for jd detection")
broke jack support for our device. Basically with that patch we never correctly see a jack insertion event, and audio is never routed to the headphones.
With just that one patch reverted, things work correctly on our system. The revert applies cleanly to linus/master.
Here is the series where that patch was originally upstreamed:
https://www.spinics.net/lists/alsa-devel/msg64331.html
If we reverted that patch upstream, would it break other devices (the "GDP Win" device?) that use the rt5645 driver? If so, how would you recommend proceeding?
Does anyone have one of the "GDP Win" devices so we can test that and our device and make sure whatever solution we end up coming up with works for everyone?
Thanks, - Ross
