An example of such a driver is the SOCFPGA's FPGA bridge driver. This driver has to get loaded early because it needs to enable FPGA components that are connected to the bridge. This FPGA bridge driver will using the reset controller API to toggle it's reset bits, thus, it needs the reset driver to be loaded as early as possible in order for it to get used properly.
