"wdc" is the "C"ontroller, the drives are "wd".  E.g. from a dmesg
from Jornada 690 from from https://dmesgd.nycbug.org - a CF card in a
PCMCIA slot:

wdc0 at pcmcia1 function 0: <SanDisk, SDCFXPS-032G, >
wdc0: memory mapped mode
atabus0 at wdc0 channel 0
wd0 at atabus0 drive 0
wd0: <SDCFXPS-032G>
wd0: drive supports 1-sector PIO transfers, LBA48 addressing
wd0: 30535 MB, 62041 cyl, 16 head, 63 sec, 512 bytes/sect x 62537328 sectors
wd0: 32-bit data port
