I can't force the ordering to be wrong, because it's the only entry in the
list. The DPAA entries are not there yet.

This is what I have now:

static const struct of_device_id of_device_ids[] __devinitconst = {
	{
		.compatible	= "simple-bus"
	},
	{
		.compatible	= "fsl,srio",
	},
	{
		.compatible	= "fsl,p4080-pcie",
	},
	{
		.compatible	= "fsl,qoriq-pcie-v2.2",
	},
	{
		.compatible	= "fsl,qoriq-pcie-v2.3",
	},
	{
		.compatible	= "fsl,qoriq-pcie-v2.4",
	},
	/* The following two are for the Freescale hypervisor */
	{
		.name		= "hypervisor",
	},
	{
		.name		= "handles",
	},
	{
		/*
		 * Warning: this entry might need to be located before those
		 * for the Fman Ethernet nodes, although using EPROBE_DEFER
		 * in the DPAA drivers could fix that.
		 */
		.compatible	= "mdio-mux",
	},
	{}
};
