TCA954x I2C switch
Each channel is represented by a separate devicetree child node.
The channel node can then be used as a standard i2c bus controller
like in the following simplified example:
/* The tca954x node must be a child of an i2c controller */
mux: tca9546a@77 {
compatible = "ti,tca9546a";
reg = <0x77>;
status = "okay";
label = "i2c_mux";
#address-cells = <1>;
#size-cells = <0>;
reset-gpios = <&gpio5 3 GPIO_ACTIVE_LOW>;
mux_i2c@0 {
compatible: "ti,tca9546a-channel"
reg = <0>;
#address-cells = <1>;
#size-cells = <0>;
temp_sens_0: tmp116@49 {
compatible = "ti,tmp116";
reg = <0x49>;
};
};
mux_i2c@1 {
compatible: "ti,tca9546a-channel"
reg = <1>;
#address-cells = <1>;
#size-cells = <0>;
temp_sens_1: tmp116@49 {
compatible = "ti,tmp116";
reg = <0x49>;
};
};
};
