Not sure what you mean by "wake up touch", but during normal operation touch
causes an interrupt which then gets serviced. When used as a wakeup source,
the bootloader runs first - not an interrupt service routine. So, different
code paths would cause different times.

Why are you concerned?

but the "wake up touch" togling the TOUCH IRQ 40 ms, which is 100 times of
regular touch. How can we reduce/minimize  this "togling time"?
