I recently asked the same thing, the answer was to use the following:

,----[ C-h f dired-maybe-insert-subdir RET ]
| dired-maybe-insert-subdir is an interactive autoloaded Lisp function in 
`dired-aux'.
| [Arg list not available until function definition is loaded.]
| 
| Insert this subdirectory into the same dired buffer.
| If it is already present, just move to it (type M-x dired-do-redisplay to 
refresh),
|   else inserts it at its natural place (as `ls -lR' would have done).
| With a prefix arg, you may edit the ls switches used for this listing.
|   You can add `R' to the switches to expand the whole tree starting at
|   this subdirectory.
| This function takes some pains to conform to `ls -lR' output.
