Perle Speed4 LE 4 port serial card

[Douglas K. Rand]

Thanks for the help! With a few changes I got it working:

Of course the '* 8' was the last one I tried. With an older SIIG card
I had to use *10 so I tried that first. Then it seems that *4 was
popular so I tried that. Finally got it with *8.

Here is the puc and uart parts of the dmesg:

puc0: <Perle Speed4 LE> port 0xec80-0xec9f,0xeca0-0xecbf mem 0xdf2fc000-0xdf2fcfff,0xdf2fd000-0xdf2fdfff irq 38 at device 0.0 on pci7

uart0: [FILTER]
uart1: <16550 or compatible> port 0x2f8-0x2ff irq 3 on acpi0
uart1: [FILTER]

It recoginzes the 4 ports uart{2..5} and all 4 work fine. I'm not sure
why both a puc0 and puc1 show up, but everything is working.

Thanks for the help. Is a PR for this useful or just extra email
noise?
