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";
|
|
#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>;
|
