| * Linear Technology / Analog Devices I2C bus switch | |
| Required Properties: | |
| - compatible: Must contain one of the following. | |
| "lltc,ltc4305", "lltc,ltc4306" | |
| - 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: | |
| - enable-gpios: Reference to the GPIO connected to the enable input. | |
| - i2c-mux-idle-disconnect: Boolean; if defined, forces mux to disconnect all | |
| children in idle state. This is necessary for example, if there are several | |
| multiplexers on the bus and the devices behind them use same I2C addresses. | |
| - gpio-controller: Marks the device node as a GPIO Controller. | |
| - #gpio-cells: Should be two. The first cell is the pin number and | |
| the second cell is used to specify flags. | |
| See ../gpio/gpio.txt for more information. | |
| - ltc,downstream-accelerators-enable: Enables the rise time accelerators | |
| on the downstream port. | |
| - ltc,upstream-accelerators-enable: Enables the rise time accelerators | |
| on the upstream port. | |
| Example: | |
| ltc4306: i2c-mux@4a { | |
| compatible = "lltc,ltc4306"; | |
| #address-cells = <1>; | |
| #size-cells = <0>; | |
| reg = <0x4a>; | |
| gpio-controller; | |
| #gpio-cells = <2>; | |
| i2c@0 { | |
| #address-cells = <1>; | |
| #size-cells = <0>; | |
| reg = <0>; | |
| eeprom@50 { | |
| compatible = "at,24c02"; | |
| reg = <0x50>; | |
| }; | |
| }; | |
| i2c@1 { | |
| #address-cells = <1>; | |
| #size-cells = <0>; | |
| reg = <1>; | |
| eeprom@50 { | |
| compatible = "at,24c02"; | |
| reg = <0x50>; | |
| }; | |
| }; | |
| }; |
