Currently the 8250_of driver only supports MEM IO type

Some development boards (Huawei D03, specifically) require
IO space access for 8250-compatible OF driver support, so
add it.
The modification is quite simple: just set the port iotype
and associated flags depending on the device address
resource type.

This no longer applies to my tree due to a patch that was sent before
yours that conflicts in the same area. Can you rebase it against my
tty-testing branch and resend?
Hi Greg,
OK, I'll do that. I will also make this small improvement to this patch:
+ if ((resource.flags & IORESOURCE_TYPE_BITS) == IORESOURCE_IO) {
+ port->iotype = UPIO_PORT;
|
V
+ if (resource_type(&resource) == IORESOURCE_IO) {
+ port->iotype = UPIO_PORT;
All the best,
John
