Input: ads7846 - re-check pendown status before reporting events
Pendown status from the PENIRQ pin is currently read only at the beginning
of a sample set. If the pen is lifted just after sampling has began then
sampled values become wrong.
This patch adds an optional platform penirq_recheck_delay attribute. If
non-zero, samples are only reported to the input subsystem if PENIRQ is
still active that long after the samples taken.
