| * 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. |
| - 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. |
| |
| |
| 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>; |
| }; |
| }; |
| }; |
