+  An i2c gate is useful to e.g. reduce the digital noise for RF tuners connected
+  to the i2c bus. Gates are similar to arbitrators in that you need to perform
+  some kind of operation to access the i2c bus past the arbitrator/gate, but
+  there are no competing masters to consider for gates and therefore there is
+  no arbitration happening for gates.
