+# 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.
