Subject[PATCH] Add support for a no-name 4 ports multiserial card
Date
It is a no-name PCI card. I found no reference to a producer so I
used the fake name "PDR".

Full lspci:
01:07.0 0780: 10b5:9050 (rev 01)
Subsystem: 10b5:1584
Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- \
ParErr- Stepping- SERR+ FastB2B-
Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- \
DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
Interrupt: pin A routed to IRQ 10
Region 1: I/O ports at ec00 [size=128]
Region 2: I/O ports at e480 [size=32]
Region 3: I/O ports at e400 [size=8]
Capabilities: [40] Power Management version 1
Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA \
PME(D0+,D1-,D2-,D3hot+,D3cold-)
Status: D0 PME-Enable- DSel=0 DScale=0 PME-
Capabilities: [48] #06 [0080]
Capabilities: [4c] Vital Product Data
