| TCA9546a I2C switch |
| |
| Each channel is represented by a separate devicetree child node |
| with a "ti,tca9546a-channel" compatible. |
| The channel node can then be used as a standard i2c bus controller |
| like in the following simplified example: |
| |
| /* The tca9546a node must be a child of an i2c controller */ |
| mux: tca9546a@77 { |
| compatible = "ti,tca9546a"; |
| reg = <0x77>; |
| |
| mux_i2c@0 { |
| compatible = "ti,tca9546a-channel"; |
| reg = <0>; |
| |
| temp_sens_0: tmp116@49 { |
| compatible = "ti,tmp116"; |
| reg = <0x49>; |
| }; |
| }; |
| |
| mux_i2c@1 { |
| compatible = "ti,tca9546a-channel"; |
| reg = <1>; |
| |
| temp_sens_1: tmp116@49 { |
| compatible = "ti,tmp116"; |
| reg = <0x49>; |
| }; |
| }; |
| }; |
| |
| compatible: "ti,tca9546a" |
