I get a Multi-I/O Controller below:
01:08.0 Communication controller: NetMos Technology PCI 9835 Multi-I/O Controller (rev 01)
Subsystem: LSI Logic / Symbios Logic 1P2S
Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
Interrupt: pin A routed to IRQ 20
Region 0: I/O ports at e050 [size=8]
Region 1: I/O ports at e040 [size=8]
Region 2: I/O ports at e030 [size=8]
Region 3: I/O ports at e020 [size=8]
Region 4: I/O ports at e010 [size=8]
Region 5: I/O ports at e000 [size=16]
I get below from pci.ids:
9710 NetMos Technology
9835 PCI 9835 Multi-I/O Controller
1000 0002 2S (16C550 UART)
1000 0012 1P2S
I have tested 8250_pci.c, it works well with it,
so we just need add the device id to the deivce
id table.
