Good afternoon Paolo. It's been a while. I hope you and the team are well.
How much extra enablement for the Snapdragon 835does 'snapdragon-edge' contain? My fear is that a lot of the most recent functionally patches have either only just gone upstream, or are currently residing in -next. In order to have a kernel which is useful, these patches would be required. I tested the kernels you posted before. mahmoh posted the results of my testing above. v5.0 gets really close, but the screen goes blank right at the last moment and no login screen is presented. My gut feeling tells me that this is an issue surrounding regulators. There are some patches in -next which tune some of the QCom regulator drivers which I believe will solve the problem. The patch you are testing works (and is actually a hard requirement for all of these devices). As mahmoh mentioned, if it wasn't working the kernels above wouldn't get much past the Grub screen. Obviously once v5.1-rc1 is released we get all our requirements for free, but it would be really nice if you guys could carry the patch in your most recent kernels until you pick up v5.1.
