		A target may contain multiple defconfigs, but only one device-tree
		configuration. Such a target may have device-drivers that are
		only enabled in a particular defconfig, while disabled in the
		others. For the kernel that boots up with disabled configuration,
		since the device-tree node exists, the of_devlink logic expects
		the driver to be probed, which is not possible. As a result, the
		sync-state remains incomplete.
		This proxy consumer driver shows a proxy-presence of the main
		driver to satisfy the sync-state.
