8250_pci and OXPCIe952

[Breno Leitao <leitao@linux.vnet.ibm.com>]

Hi Greg,

I put an OXPCIe952 card on my machine (PPC), and the driver is not
running fine.
First of all, it identifies 8 ports, which is wrong. Also, it says

0000:01:00.1: ttyS1 at MMIO 0x3c05ff7fd200 (irq = 66) is a 16C950/954

and the driver loads without any other error, although it's not working.

So, my question is: Does this driver support this chipset? Was it ever
tested on PPC ?


Thanks
Breno
