Please ignore this patch. It was an older version which was sent by 
mistake.

Thanks,

add binding information for tps6507x touchscreen input.

"ti,min-pressure" was added as TI specific binding because it
was specific to tps6507x IP and not applicable or relevant for
other touchscreen drivers.

Seems like you would need other properties from the common touchscreen 
binding.
