ctrl_xxx() is an antiquated SH interface, while __raw_xxx is the standard
API that accomplishes the same thing. As such, this converts the
remaining sh-sci straggles over, which enables the driver to be wired up
for ARM SH-Mobile CPUs as well.

Several IOC3 and IOC4 drivers misuse the __devinit and __devexit section
markers. Use __init and __exit instead as appropriate, then add __devinit
and __devexit where they really belong for PCI drivers.
Also make ioc4_serial_init static.

This is V2 of early serial console support for the sh-sci
driver. The early serial console is using early platform
devices and "earlyprintk". To use this feature the early
platform devices must be broken out to one device per port
and the desired port should be selected on the kernel command
line like: "earlyprintk=sh-sci.N[,baudrate][,keep]"

Do not read IIR in serial8250_start_tx when UART_BUG_TXEN
Reading the IIR clears some oustanding interrupts so it is not safe.
Instead, simply transmit immediately if the buffer is empty without

Intel(R) PXA27x Processor Family Specification Update (Nov 2005)
says:
E75. UART: Baud rate may not be programmed correctly on
back-to-back writes.
Problem:
When programming the Divisor Latch registers, Low and High (DLL and
DLH), with back-to-back writes, the second register write may not
take effect. The result is an incorrect baud rate.
Workaround:
After programming the first Divisor Latch register, read and verify
it before programming the second Divisor Latch register.
This was hit when changing the baud rate from 115200 to 9600 while
receiving characters at 9600 Bd.
And fixed indention of some comments nearby.

Unfortunately, one cannot hold on to the struct firmware
that request_firmware_nowait() hands off, which is needed
in some cases. Allow this by requiring the callback to
free it (via release_firmware).
Additionally, give it a gfp_t parameter -- all the current
users call it from a GFP_KERNEL context so the GFP_ATOMIC
isn't necessary. This also marks an API break which is
useful in a sense, although that is obviously not the
primary purpose of this change.

Currently serial ports on SH CPUs get disabled too early, because the
sci_tx_empty() routine claims to not be able to detect whether the
transmission has been completed and just always returns TIOCSER_TEMT. This
results in corrupt output of last characters if the port is not open for
reading at the same time. It is however possible to detect whether
transmission has been completed. Use the TEND bit of the status register
for this.

Most of the irq_req_t typedef'd struct can be re-worked quite
easily:
(1) IRQInfo2 was unused in any case, so drop it.
(2) IRQInfo1 was used write-only, so drop it.
(3) Instance (private data to be passed to the IRQ handler):
Most PCMCIA drivers using pcmcia_request_irq() to actually
register an IRQ handler set the "dev_id" to the same pointer
as the "priv" pointer in struct pcmcia_device. Modify the two
exceptions (ipwireless, ibmtr_cs) to also work this waym and
set the IRQ handler's "dev_id" to p_dev->priv unconditionally.
(4) Handler is to be of type irq_handler_t.
(5) Handler != NULL already tells whether an IRQ handler is present.
Therefore, we do not need the IRQ_HANDLER_PRESENT flag in
irq_req_t.Attributes.

The sh-sci code conditionalized the clock framework support in order to
give the other platforms a chance to catch up. sh64 supported this some
time ago and the forthcoming ARM changes handle this as well, this leaves
h8300 as the odd one out. H8300 has had since 2.5 to merge it's sh-sci
support upstream, and has yet to do so. At this point I will no longer be
holding back the driver to support an unreponsive architecture, 7 years
is quite enough of a grace period. Support is easily implemented on the
architecture if and when it ever decides to merge its changes upstream.

RSC and LOM devices have fixed speed settings.
We already had some code to match and handle "rsc" named devices on
E250 systems, but we also have to handle 'rsc-console', 'rsc-control',
and 'lom-console'.
Also, in order to get this right regardless of what 'output-device'
happens to be, explicitly pass the UART device node pointer to this
routine.

This tells the logic to ignore the line match when deciding whether the
device is the OpenFirmware specified console device or not.
This is going to be used in the SU driver for rsc-console detection.
There is probably a better way to handle this, but this is the least
intrusive solution for now which we can validate won't break any other
cases.

These device nodes are named "rsc-console" and "rsc-control" rather
than 'serial', but the device_type property is 'serial' so we'll
tip off of that for detection.

Other Sun serial drivers do not do this, and if we keep it this way
it ends up registering all serial devices as consoles rather than
just the one which we explicitly register via sunserial_console_match()
which uses add_preferred_console().
