+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.
