I tested this using lcd7 cape connected to beaglebone black. The latest
kernel I could find on this board was a TI BSP based v3.14 kernel. So I
had to port these patches to that kernel. Cc Robert Nelson to see if he
knows about a more recent kernel supporting that cape.

What is missing from mainline for the black?

(I thought it was fully supported by now.)
 

I did not see any breakage with these patches applied although I did not
see any noticeable performance improvement as well.

So, the jumping on pen-up persists, right?  That means the patch
series does not provide a general fix for that issue.
 

I also tested this series on AM335x EVM using the v3.18-rc5 kernel.
Again, no breakage but no improvement as well.

You still have jumps on a pen up event?

Thanks,
