Patch from Sascha Hauer

This patch moves the i.MX uart resources and the gpio pin setup to the
board files. This allows the boards to decide how many internal uarts
are connected to the outside world and whether they use rts/cts or
not.

A number of small issues are fixed, and added the header file, missed from the
original series. With this, driver should be pretty stable as tested among
both platform-device-driven and "old way" boards. Also added missing GPL
statement , and updated year field on existing ones to reflect
code update.

SCC uart sends a break sequence each time it is stopped with the
CPM_CR_STOP_TX command. That means that each time an application closes the
serial device, a break is transmitted. To fix this, graceful tx stop is
issued for SCC.

x86 SMP breaks as a result of the previous change, we have no real
option other than to add locking to the 8250 console write function.
If an oops is in progress, try to acquire the lock.  If we fail to
do so, continue anyway.

A bug report from Gerd Hoffmann has highlighted that unconditionally
enabling the transmit interrupt at the end of console writes is very
bad.

In Gerd's case, it causes the test for buggy UARTs to give false
positives, incorrectly identifying ports as buggy when they are not.

Moreover, if we unconditionally enable the interrupt, and the port
is sharing it's interrupt with other ports, there is the very real
possibility that we'll cause an interrupt storm.  (Not all ports use
OUT2 as an interrupt mask.)

Hence, revert part of f91a3715 and
all of f5968b37 until a better solution
can be found.

I've noticed that the 8250/Au1x00 driver (drivers/serial/8250_au1x00.c)

The locking for the uart_port is over complicated, and can be
simplified if we introduce a flag to indicate that a port is "dead"
and will be removed.

This also helps the validator because it removes a case of non-nested

Current address translation methods can produce wrong results, because
virt_to_bus and vice versa may not produce correct offsets on dma-allocated
memory. The right way is, while tracking both phys and virt address of the
window that has been allocated for boffer descriptors, and use those
numbers to compute the offset and make translation properly.

This is intended to make the driver code more generic and flexible,
to get rid of board-specific layouts within driver, and generic rehaul,
yet keeping compatibility with the existing stuff utilizing it, being

This ugly hack add support for Siemens MC45 PCMCIA GPRS card (which is
identical to Possio GCC, and which is offered by one of our local GPRS
providers).  Card has unfortunate feature that after poweron oxcf950 chip
is fully powered and works, but attached MC45 modem is powered down :-(
There is a special sequence (which takes 1 sec :-( ) to poweron MC45 (and
after MC45 powers on, it takes more than 2 secs until firmware fully
boots...) which needs to be executed after all powerons.

I'm really not familiar with PCMCIA subsystem, so I have no idea whether I
should issue request_region() on rest of oxcf950 address range (0-7 is
UART, 8-F are special configuration registers), or how this should be
better integrated with PM system and so on - I just put it in same place
where another hack already lived...

Card uses 18.432MHz XTAL, so to get it to work you must add lines below to
the /etc/pcmcia/serial.opts.

Instead of the two status values struct pcmcia_device->p_state and state,

Remove the assumption that driver_register() returns the number of devices
bound to the driver.  In fact, it returns zero for success or a negative
error value.

dio_module_init() used the device count to automatically unregister and
unload drivers that found no devices.  That might have worked at one time,
but has been broken for some time because dio_register_driver() returned
either a negative error or a positive count (never zero).  So it could only
unregister on failure, when it's not needed anyway.

This functionality could be resurrected in individual drivers by counting
devices in their .probe() methods.
