1* Linear Technology / Analog Devices I2C bus switch2 3Required Properties:4 5 - compatible: Must contain one of the following.6 "lltc,ltc4305", "lltc,ltc4306"7 - reg: The I2C address of the device.8 9 The following required properties are defined externally:10 11 - Standard I2C mux properties. See i2c-mux.yaml in this directory.12 - I2C child bus nodes. See i2c-mux.yaml in this directory.13 14Optional Properties:15 16 - enable-gpios: Reference to the GPIO connected to the enable input.17 - i2c-mux-idle-disconnect: Boolean; if defined, forces mux to disconnect all18 children in idle state. This is necessary for example, if there are several19 multiplexers on the bus and the devices behind them use same I2C addresses.20 - gpio-controller: Marks the device node as a GPIO Controller.21 - #gpio-cells: Should be two. The first cell is the pin number and22 the second cell is used to specify flags.23 See ../gpio/gpio.txt for more information.24 - ltc,downstream-accelerators-enable: Enables the rise time accelerators25 on the downstream port.26 - ltc,upstream-accelerators-enable: Enables the rise time accelerators27 on the upstream port.28 29Example:30 31 ltc4306: i2c-mux@4a {32 compatible = "lltc,ltc4306";33 #address-cells = <1>;34 #size-cells = <0>;35 reg = <0x4a>;36 37 gpio-controller;38 #gpio-cells = <2>;39 40 i2c@0 {41 #address-cells = <1>;42 #size-cells = <0>;43 reg = <0>;44 45 eeprom@50 {46 compatible = "atmel,24c02";47 reg = <0x50>;48 };49 };50 51 i2c@1 {52 #address-cells = <1>;53 #size-cells = <0>;54 reg = <1>;55 56 eeprom@50 {57 compatible = "atmel,24c02";58 reg = <0x50>;59 };60 };61 };62
