This file provides very little in the way of actual schema but does provide a convenient intro to what an i2c-gate node actually represents.

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.
