It has no device entry in uart_bus_pci.c. Unfortunately, while I'm able to get= the device to show up if I add it, I can't communicate with it using cu. I'm ab= le to get two different USB serial devices to talk using the same null modem c= able and the same commands (minus the devices), so I don't suspect it's the devi= ce. I *assume* this applies to CURRENT as well. To test, I added `{ 0x8086, 0x0c5f, 0xffff, 0, "Atom Processor S1200 UART", 0x10},` to uart_bus_pci.c. The driver is loaded with this change, however it doesn't seem to function. ```uart2@pci0:0:20:0: class=3D0x070002 rev=3D0x02 hdr=3D0x00 vendor=3D= 0x8086 device=3D0x0c5f subvendor=3D0x15d9 subdevice=3D0x0651 vendor =3D 'Intel Corporation' device =3D 'Atom Processor S1200 UART' class =3D simple comms subclass =3D UART ``` If I use this change, like some other Intel serial devices, it does not load the module and says "no driver attached". ```{ 0x8086, 0x0c5f, 0xffff, 0, "Atom Processor S1200 UART", 0x10, 24 * DEFAULT_RCLK, 2 }, ``` Not sure how to proceed with this. Would appreciate any pointers.
