+- i2c-bus
+	For I2C adapters that have child nodes that are a mixture of both I2C
+	devices and non-I2C devices, the 'i2c-bus' subnode can be used for
+	populating I2C devices. If the 'i2c-bus' subnode is present, only
+	subnodes of this will be considered as I2C slaves. The properties,
+	'#address-cells' and '#size-cells' must be defined under this subnode
+	if present.
