The convention that we've been using is:

10004000-10004fff : mb:aaci
  10004000-10004fff : aaci-pl041
10005000-10005fff : mb:mmci
  10005000-10005fff : mmci-pl18x
10006000-10006fff : mb:kmi0
  10006000-10006fff : kmi-pl050
10007000-10007fff : mb:kmi1
  10007000-10007fff : kmi-pl050
10009000-10009fff : mb:uart0
  10009000-10009fff : uart-pl011
1000a000-1000afff : mb:uart1
  1000a000-1000afff : uart-pl011
1000b000-1000bfff : mb:uart2
  1000b000-1000bfff : uart-pl011
1000c000-1000cfff : mb:uart3
  1000c000-1000cfff : uart-pl011

The parent resource uses the device name.  The child resource is the
driver name.  That (a) avoids useless duplication of data in /proc/iomem
and (b) is more informative when you look at /proc/iomem about what's
where.
