#
# Use two different rules for GPIO's.
#
# 1. The first rule (gpiochip0) allows to configure the GROUP and MODE of
# the 'export' and 'unexport' files. This is basically executed once on
# boot and it's needed so a normal user (with group 'digiapix')
# is able to export/unexport gpios.
#
# 2. The second rule configures the GROUP and MODE of the sysfs files that
# are created whenever a 'gpio' is exported.
#
# This way we filter out multiple gpiochipX events that we don't want to attend
