  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"
