How to correctly load a driver without device tree?

[kipade]

Now, most of kernel device are initialized by its driver according by
what described within device tree block. Here, the dtb was parsed
and used during kernel booting. If so, I want to load a device driver
after kernel booting using insmod, there would be no device tree
block present, so, the device would not be configured correctly.
so, how to make it usable?

Regards,
kipade.
