Gates are similar to arbitrators in that you need to perform15 some kind of operation to access the i2c bus past the arbitrator/gate, but16 there are no competing masters to consider for gates and therefore there is17 no arbitration happening for gates.18 19allOf:20 - $ref: /schemas/i2c/i2c-controller.yaml21 22properties:23 $nodename:24 const: i2c-gate25 26additionalProperties: true27 28examples:29 - |30 i2c-gate {31 #address-cells = <1>;32 #size-cells = <0>;33 ak8975@c {34 compatible = "asahi-kasei,ak8975";35 reg = <0x0c>;36 };37 };38...39
