8250_pci and OXPCIe952

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

How many should there be?

What should the address and irq be?

I don't know.

I don't know.

Greg,

Only two UARTs in this chipset.

These address seems to be fine, although the driver is not working. I suppose that there is something that is broken in the device driver.

Thanks
