Gates are similar to arbitrators in that you need to perform 15 some kind of operation to access the i2c bus past the arbitrator/gate, but 16 there are no competing masters to consider for gates and therefore there is 17 no arbitration happening for gates. 18 19allOf: 20 - $ref: /schemas/i2c/i2c-controller.yaml 21 22properties: 23 $nodename: 24 const: i2c-gate 25 26additionalProperties: true 27 28examples: 29 - | 30 i2c-gate { 31 #address-cells = <1>; 32 #size-cells = <0>; 33 ak8975@c { 34 compatible = "ak,ak8975"; 35 reg = <0x0c>; 36 }; 37 }; 38... 39 40
