Instead, have module parameters that take the sizes and alignments you'd
like
to allocate and expose to userspace.  Better still would be some sort of
dynamic allocation (e.g. open a fd, ioctl to set the requested
size/alignment,
if it succeeds you can mmap it, and when the fd is closed the region is
freed).

No module parameters please, this is not the 1990's.

Use device tree, that is what it is there for.

Since when is the device tree for indicating desired allocations?  This is not
hardware description.

If module parameters are unacceptable, then I'd suggest dynamic allocation as
described above.
