Hi,
A while ago XR17V3521 was added to share/misc/pci_vendors, and I happen
to have a card using that chip:
none0@pci0:7:0:0: class=0x070002 card=0x00000000 chip=0x035213a8
rev=0x03 hdr=0x00
vendor = 'Exar Corp.'
device = 'XR17V3521 Dual PCIe UART'
class = simple comms
subclass = UART
The only noise I see so far from that card is,
pcib7: <PCI-PCI bridge> at device 30.0 on pci0
pci7: <PCI bus> on pcib7
Can some kind soul please point me in the direction where I should look
to get something more useful out of it, I presume sys/dev/puc/pucdata.c
but this is where I'm lost, can't find any docs on how this file is built.
The card is a VSCom 200PCIe, apparently with a XR17V3521 chip, the chip
manual says "16550 compatible register set"
Thanks!
