I back ported this series onto v3.15.1 in order to try this out on a custom, beaglebone-like board. With this series, the touch is really broken. (I had fixed the pen up problem in a totally different way for a customer, and so I wanted to try out your solution.)
I will try to port the board code to a more recent kernel to try your series again. With which kernel version did you test your patches?
And which board?
Thanks, Richard
