Hello,
I have tried your patches by cloning [1] and copying the

It compiles & runs, but I'm seeing lots of pen-down/pen-up
events when I'm not touching the screen.
Any suggestions?

I manage to freeze am335x-evm with those patches and I think Vignesh
is looking into this.

This series of patches fix TSC defects related to lag in touchscreen
performance and cursor jump at touch release. The lag was result of
udelay in TSC interrupt handler. Cursor jump due to false pen-up event.
The patches implement Advisory 1.0.31 in silicon errata of am335x-evm
