# By using an overlay, we should be able to support multiple pinouts
# using the same image.  The overlays go into /lib/dtoverlays.
# There names are: [hw-version]-driver.dtbo
#  e.g. /lib/dtoverlays/MTRV1-0.0-pps.dtbo
# The idea is that mts-io will search for the overlays, and install the
# appropriate device tree overlay for the current hw-version.
