Writing alsa driver for Roland Sound Canvas SCP-55 pcmcia card

Writing alsa driver for Roland Sound Canvas SCP-55 pcmcia card

[John Shillinglaw]

Hello,

I am starting to write a driver for Roland's SCP-55 pcmcia sound card
( midi port at 330, 2 channels of audio play/record, and internal GM
synth ).

I have the old drivers from the person who was previously working on a
driver for this card, and have found the driver writing documentation
from alsa-project.org which focuses on pci cards.

Can anyone point me to resources and help for developing an alsa driver
for a pcmcia card?

Thanks,
John Shillinglaw

PCMCIA has two different types: PCCard and CardBus.  The latter is
almost identical with the normal PCI driver, so the all topics
described in my tutorial are valid.

The former, PCCard, is a different one.  You sholud check some other
drivers like vxpocket or pdaudiocf.  (Better to check the latest CVS
version to follow the recent change of kernels).
