xiaomi-markw Atmel touchscreen

[TailsFanLOL]

Hello! This technically isn't required for Android, but please somehow make markw hardware revisions with the atmel,maxtouch touch panel work in the dt. This is required for pmOS. Thanks.

I believe those devices have multi-sourced touchscreens, in which case it's non-trivial for lk2nd to detect which specific touchscreen is there.

One could probably write a fixup driver and try talking to the touchscreen before boot to figure out which one it is, but this obviously requires someone with the hardware on hand as well as some know-how to correctly detect the present touchscreen.

If I recall correctly, the suggestion for now was to manually build a fixed up verison of lk2nd for a given device.

Yeah. And I don't speak C good enough yet so I can't do it...

Current workaround is to do this:

That is why comments were there in msm8953 fork to be able to make custom build for atmel variants easily

Yeah lol
