I'm porting a linux kernel module. It used to create a device file for itself (using dirty hacks with syscalls from kernelspace), but now I want to do this in udev. Where can I find documentation on supporting udev in in kernel module?

Note that module itself is not a device driver. It serves as a multiplexor for a set of drivers. Therefor default ways of registering devices (i.e. pci ones) are not suitable for my task.
