* NXP PCA954x I2C bus switch

Required Properties:

  - compatible: Must contain one of the following.
    "nxp,pca9540", "nxp,pca9542", "nxp,pca9543", "nxp,pca9544",
    "nxp,pca9545", "nxp,pca9546", "nxp,pca9547", "nxp,pca9548"

  - reg: The I2C address of the device.

  The following required properties are defined externally:

  - Standard I2C mux properties. See i2c-mux.txt in this directory.
  - I2C child bus nodes. See i2c-mux.txt in this directory.

Optional Properties:

  - reset-gpios: Reference to the GPIO connected to the reset input.


Example:

	i2c-switch@74 {
		compatible = "nxp,pca9548";
		#address-cells = <1>;
		#size-cells = <0>;
		reg = <0x74>;

		i2c@2 {
			#address-cells = <1>;
			#size-cells = <0>;
			reg = <2>;

			eeprom@54 {
				compatible = "at,24c08";
				reg = <0x54>;
			};
		};

		i2c@4 {
			#address-cells = <1>;
			#size-cells = <0>;
			reg = <4>;

			rtc@51 {
				compatible = "nxp,pcf8563";
				reg = <0x51>;
			};
		};
	};
