32b53076c3 serial: sh-sci: Convert tremaining ctrl_xxx I/O routines to __raw_xxx.
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.

2ea5d35a49 ioc3/ioc4: various section fixes
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.

7b6fd3bf82 sh-sci: Extend sh-sci driver with early console V2
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]"

68cb4f8e24 Serial: Do not read IIR in serial8250_start_tx when UART_BUG_TXEN
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
regard to IIR.

c934878cc0 Serial: pxa: work around Errata #75
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.

Currently jsm is showing the following message when loaded:

IRQ 432/JSM: IRQF_DISABLED is not guaranteed on shared IRQs

It's because the request_irq() is called using IRQF_DISABLED
and IRQF_SHARED.
Actually there is no need to use IRQF_DISABLED in this driver.

9ebfbd45f9 firmware_class: make request_firmware_nowait more useful
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.
