Fix up Conflicts in:
- drivers/tty/serial/8250_pci.c
Trivial conflict with removed duplicate device ID
- drivers/tty/serial/atmel_serial.c
Annoying silly conflict between "specify the port num via
platform_data" and other changes to atmel_console_init

Currently, ".setup" function is not set.
As a result, when detecting our IOH's uart device without pch_uart, kernel panic
occurs at the following of pciserial_init_ports().
for (i = 0; i < nr_ports; i++) {
if (quirk->setup(priv, board, &serial_port, i))
break;
So, this patch adds the ".setup" function.
We can use pci_default_setup because our IOH's uart is compatible with 16550.

The EFR (Enhenced-Features-Register) is located at a different offset
than the other devices supporting UART_CAP_EFR. This change add a special
setup quick to set UPF_EXAR_EFR on the port. UPF_EXAR_EFR is then used to
the port type to PORT_XR17D15X since it is for sure a XR17D15X uart.

This patch adds support for the Rosewill RC-305 four-port PCI serial
card, and probably any other four-port serial cards based on the
Moschip MCS9865 chip, assuming that the EEPROM on the card was
programmed in accordance with Table 6 of the MCS9865 EEPROM
Application Note version 0.3 dated 16-May-2008, available from the
Moschip web site (registration required).
This patch is based on an earlier patch [1] for the SYBA 6x serial
port card by Ira W. Snyder.

The purpose of the patch is to add EEH support to the 8250_PCI driver
for the IBM/Digi PCIE 2port Async EIA-232 Adapter that uses a PLX
chipset on the PPC platforrm. Basic support for this adapter was
recently added https://lkml.org/lkml/2011/5/11/341
This patch was created against the linux-next kernel

Timedia/SUNIX PCI cards with both serial and parallel ports are
currently supported by 8250_pci and parport_pc individually. Moving
that support into parport_serial allows using both types of ports at the
same time.
This was successfully tested with a SUNIX 4079T.

This function, if present, is called early on by the 8250_pci probe; it
can be used to reject devices meant for parport_serial. (The .init
function cannot be used for this purpose, as it is also called by
parport_serial.)

Add I/O based support for serial and parallel ports of the following
chips:
Vendor: Moschip (0x9710)
Parts (device IDs)
* 9900 (0x9900)
* 9904 (0x9904
* 9901 (0x9912, also sold as 9912)
* 9922 (0x9922)
On all chips but the 9900, a single port is provided per PCI subdevice
(subvendor-ID 0xA000, subdevice-IDs 0x1000 for serial, 0x2000 for
parallel with proper class codes). In cascading configurations, the
9900 provides two devices per subdevice, with subvendor-ID 0xA000 and
subdevice-IDs 0x30ps where p is the number of parallel ports and s the
number of serial ports.
Basic testing was only done on the serial part of a 9912 to the point
where it can be used for a serial kernel console, and advanced features
are completely untested. It is possible to reduce functionality of the
chips by adding a configuration EEPROM, and the datasheet [1] is
inconsistent w.r.t subdevices in the 4s+2s1p and 2s1p+4s
configurations. The subdevice-ID 0x3012 should likely read 0x3011 with
a serial port in function 3, which would be consistent with the BAR
layouts. For now, the drivers ignore subdevices with ID 0x1000 and no
class code.
The parallel ports are integrated in parport_serial even for purely
parallel parts to reduce the footprint of the patch.

Intel EG20T PCH has UART device which is compatible with 8250.
Currently, with general configuration, the PCH UART driver is not loaded
but 8250 standard driver is loaded. Therefore, in case of using PCH
UART driver, need to disable 8250 pci function. However, this procedure
is not best solution. This patch, in 8250_pci, if the device is the PCH
or the family IOH, '-ENODEV' is returned. As a result, disabling
8250-pci processing becomes unnecessary.

Add support to the 8250 PCI serial driver for the Digi/IBM PCIe 2-port Async EIA-232 Adapter.
Oxford Semiconductor produces a 2/4/8 port UART (OXPCIe952/OXPCIe954/OXPCIe958) chip
called the Tornado, that can be used to create a very simple serial board product.
The kernel sources currently have just 2 vendors using this chip, which is Oxford and Mainpipe.
This new Digi/IBM serial product now uses it as well.
Rather than create a long running comment of vendors using the chip, the one changed comment
in the patch below now just lists "For Oxford Semiconductor Tornado based devices" to be a
more generic comment for all vendors that end up using the Oxford Tornado chip.

The serial drivers are really just tty drivers, so move them to
drivers/tty/ to make things a bit neater overall.
This is part of the tty/serial driver movement proceedure as proposed by
Arnd Bergmann and approved by everyone involved a number of months ago.
