Hello Henrik,

Thank you for your recommendations.

I didn't know that there was a newer version of cyttsp_xydata struct.
I thought I based my work on the last version of Cypress driver.
Didn't know about Dudley Du's work either. It seems that both drivers
are for the same device family.

I'll take a look at Dudley's patch-set and also contact him to join efforts.

Best regards,
