Could you please try the patch below and see if the touchscreen still
works for you? It should be applied on top of your patch.

Sorry for coming back late, we switched I2C IP so I had to write a new 
driver for it before trying this out again.

The irq balancing seem to work as in you patch. I didn't run exactly
you patch, I took some of the changes into my code, since we can not
provide the callbacks.

I have also done some other small changes, to saves us one of five I2C 
transactions in polling mode.

I Will post this incremental patch in a couple of minutes.

Thanks
