0001 Common i2c arbitration bus properties.
0002
0003 - i2c-arb child node
0004
0005 Required properties for the i2c-arb child node:
0006 - #address-cells = <1>;
0007 - #size-cells = <0>;
0008
0009 Optional properties for i2c-arb child node:
0010 - Child nodes conforming to i2c bus binding
0011
0012
0013 Example :
0014
0015 /*
0016 An NXP pca9541 I2C bus master selector at address 0x74
0017 with a NXP pca8574 GPIO expander attached.
0018 */
