18c576f950 serial: serial_cs: oxsemi quirk breaks resume
Quirk is applied on all cards with given manfid (is it that correct?).
Unfortunately, that quirk breaks resume on zaurus with billionton
bluetooth card inserted: c950ctrl is 0 and outb() faults.

I believe it is simply not a multiport card.  (info->multi == 1).  ...
...  confirmed by printks.

16ae2a877b serial: Fix crash if the minimum rate of the device is > 9600 baud
In that situation if the old rate is invalid and the new rate is invalid
and the chip cannot do 9600 baud we report zero, which makes all the

Instead force the rate based on min/max

4547be7809 serial-core: resume serial hardware with no_console_suspend
Perform a tricky suspend/resume even with no_console_suspend.

With no_console_suspend, kernel skips serial port suspend/resume and the
serial hardware may remain in undefined state after resume. It actually
happens on devices that don't have BIOS that handle serial
initialization. It makes impossible to use serial console after resume.

Devices affected by this problem include:
Sharp Zaurus devices
Several PXA based ARM embedded boards

The patch does:
- Save the hardware state
- Perform buffer flush in time of its suspend call
- Tell the driver that port is suspended
- But still accept new data
- And keep console hardware in state that allows to send them

It allows to capture late console messages without breaking console
after resume.

This is just a resend of a patch discussed in these threads, as the
patch was not yet applied.

list, later LKML)

02ab851324 serial/pmac_zilog: Workaround problem due to interrupt on closed port
It seems that in qemu, we can see an interrupt in R3 despite the
fact that it's masked in W1. The chip doesn't actually issue an
interrupt, but we can "see" it when taking an interrupt for the
other channel. This may be a qemu bug ... or not, so let's be
safe and avoid calling into the UART layer when that happens which
woulc cause a crash.

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.

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.

b1516803d5 serial: sh-sci: Fix too early port disabling.
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.
