Common i2c arbitration bus properties.
- i2c-arb child node
Required properties for the i2c-arb child node:
- #address-cells = <1>;
- #size-cells = <0>;
Optional properties for i2c-arb child node:
- Child nodes conforming to i2c bus binding
Example :
/*
An NXP pca9541 I2C bus master selector at address 0x74
with a NXP pca8574 GPIO expander attached.
*/
arb@74 {
compatible = "nxp,pca9541";
reg = <0x74>;
i2c-arb {
#address-cells = <1>;
#size-cells = <0>;
gpio@38 {
compatible = "nxp,pca8574";
reg = <0x38>;
#gpio-cells = <2>;
gpio-controller;
};
};
};
