Subject: [PATCH] Serial MRi MRI-PCIDS1 dual port serial card
Date: Thu, 07 Apr 2005 19:54:08 +0100 [thread overview]
Message-ID: <425581D0.5010409@unsolicited.net> (raw)
This trivial patch against 2.6.11.6 adds support for the MRi PCIDS1 dual
port serial card. This card is a little controversial since it is the
subject of a PCI vendor/device ID clash. (See
http://www.ussg.iu.edu/hypermail/linux/kernel/0303.1/0516.html). I have
for now just used the hex ID 0x950a. The divisor was part calculated
part iterated, so may not be exactly correct (but works for me at all
settings between 300 - 115300 bps).
Cheers
David
