Yes, I'll use that.  The underscore versus dash doesn't
matter...

I put it in misc/ because lan966xc_pci.c, which also uses
a pci-ep-bus, is located there.  That driver also calls
of_platform_default_populate(), though it also loads a
DT overlay which isn't needed here.

It is indeed tiny, and your comment makes me think it
could easily become a generic driver (along the lines
of "simple-mfd-i2c.c").  That way other similar future
SoCs could just add their compatible string.

So two questions (for anyone):
- Would that be preferred--rename this to target a generic
   situation?  For example, "static-pci-ep-bus.c"?
- Where should such a driver be located?  For example,
   drivers/misc/, drivers/pci/controller/, or something else?
