| description: | | |
| 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. | |
