For example, from r336976:

| Index: sys/dev/jedec_ts/jedec_ts.c
| ===================================================================
| --- sys/dev/jedec_ts/jedec_ts.c	(revision 336975)

| +	    "jedec_ts(4) driver; see COMPATIBILITY section of jedec_dimm(4)");

|  }

So you might add

    gone_in_dev(dev, 12,
        "drm2(4) driver; use one of the graphics/drm-* drivers instead");

Or something along those lines.

Hope that helps,
