1* NXP PCA954x I2C bus switch
2
3Required Properties:
4
5  - compatible: Must contain one of the following.
6    "nxp,pca9540", "nxp,pca9542", "nxp,pca9543", "nxp,pca9544",
7    "nxp,pca9545", "nxp,pca9546", "nxp,pca9547", "nxp,pca9548"
8
9  - reg: The I2C address of the device.
10
11  The following required properties are defined externally:
12
13  - Standard I2C mux properties. See i2c-mux.txt in this directory.
14  - I2C child bus nodes. See i2c-mux.txt in this directory.
15
16Optional Properties:
17
18  - reset-gpios: Reference to the GPIO connected to the reset input.
19  - i2c-mux-idle-disconnect: Boolean; if defined, forces mux to disconnect all
20    children in idle state. This is necessary for example, if there are several
21    multiplexers on the bus and the devices behind them use same I2C addresses.

24Example:
25
26	i2c-switch@74 {
27		compatible = "nxp,pca9548";
28		#address-cells = <1>;
29		#size-cells = <0>;
30		reg = <0x74>;
31
32		i2c@2 {
33			#address-cells = <1>;
34			#size-cells = <0>;
35			reg = <2>;
36
37			eeprom@54 {
38				compatible = "at,24c08";
39				reg = <0x54>;
40			};
41		};
42
43		i2c@4 {
44			#address-cells = <1>;
45			#size-cells = <0>;
46			reg = <4>;
47
48			rtc@51 {
49				compatible = "nxp,pcf8563";
50				reg = <0x51>;
51			};
52		};
53	};
