0001 * Linear Technology / Analog Devices I2C bus switch
0002
0003 Required Properties:
0004
0005 - compatible: Must contain one of the following.
0006 "lltc,ltc4305", "lltc,ltc4306"
0007 - reg: The I2C address of the device.
0008
0009 The following required properties are defined externally:
0010
0011 - Standard I2C mux properties. See i2c-mux.yaml in this directory.
0012 - I2C child bus nodes. See i2c-mux.yaml in this directory.
0013
0014 Optional Properties:
0015
0016 - enable-gpios: Reference to the GPIO connected to the enable input.
0017 - i2c-mux-idle-disconnect: Boolean; if defined, forces mux to disconnect all
0018 children in idle state. This is necessary for example, if there are several
0019 multiplexers on the bus and the devices behind them use same I2C addresses.
0020 - gpio-controller: Marks the device node as a GPIO Controller.
0021 - #gpio-cells: Should be two. The first cell is the pin number and
0022 the second cell is used to specify flags.
0023 See ../gpio/gpio.txt for more information.
0024 - ltc,downstream-accelerators-enable: Enables the rise time accelerators
0025 on the downstream port.
0026 - ltc,upstream-accelerators-enable: Enables the rise time accelerators
0027 on the upstream port.

0030
0031 ltc4306: i2c-mux@4a {
0032 compatible = "lltc,ltc4306";
0033 #address-cells = <1>;
0034 #size-cells = <0>;
0035 reg = <0x4a>;
0036
0037 gpio-controller;
0038 #gpio-cells = <2>;
0039
0040 i2c@0 {
0041 #address-cells = <1>;
0042 #size-cells = <0>;
0043 reg = <0>;
0044
0045 eeprom@50 {
0046 compatible = "atmel,24c02";
0047 reg = <0x50>;
0048 };
0049 };
0050
0051 i2c@1 {
0052 #address-cells = <1>;
0053 #size-cells = <0>;
0054 reg = <1>;
0055
0056 eeprom@50 {
0057 compatible = "atmel,24c02";
0058 reg = <0x50>;
0059 };
0060 };
0061 };
