660ac5f48a serial: omap: stick to put_autosuspend
Everytime we're done using our TTY, we want
the pm timer to be reinitilized. By sticking
to pm_runtime_pm_autosuspend() we make sure
that this will always be the case.

The idea behind this patch is to make sure we
will always reinitialize the pm timer so that
we don't fall into a situation where pm_runtime_put()
expires right away (if timer was already about to
expire when we made the call to pm_runtime_put()).

While suspending right away wouldn't cause any
issues, reinitializing the pm timer can help us
avoiding unnecessary context save & restore
operations (which are somewhat expensive) if there's
another read/write/set_termios request coming right
after. IOW, we are trying to make sure UART is still
powered up while it's still under heavy usage.

ed6fe9d614 Fix order of arguments to compat_put_time[spec|val]
Commit 644595f896 ("compat: Handle COMPAT_USE_64BIT_TIME in
net/socket.c") introduced a bug where the helper functions to take
either a 64-bit or compat time[spec|val] got the arguments in the wrong
order, passing the kernel stack pointer off as a user pointer (and vice
versa).

Because of the user address range check, that in turn then causes an
EFAULT due to the user pointer range checking failing for the kernel
address.  Incorrectly resuling in a failed system call for 32-bit
processes with a 64-bit kernel.

On odder architectures like HP-PA (with separate user/kernel address
spaces), it can be used read kernel memory.

current code only works because struct uart_port
is the first member on the uart_omap_port structure.

If, for whatever reason, someone puts another
member as the first of the structure, that cast
won't work anymore. In order to be safe, let's use
a container_of() which, for now, gets optimized into
a cast anyway.

1d65c0b126 serial: New serial driver SCCNXP
This driver is a replacement for a SC26XX driver with a lot of
improvements and new features.
The main differences from the SC26XX driver:
- Removed dependency on MIPS. Driver can be used on any platform.
- Added support for SCC2681, SCC2691, SCC2692, SC28L91, SC28L92,
  SC28L202, SCC68681 and SCC68692 ICs.
- Using devm_-related functions.
- Improved error handling of serial port, improved FIFO handling.
- Ability to load multiple instances of drivers.

To avoid the possibility of regression, driver SC26XX left in the
system to confirm the stability of the driver on platforms where
it is being used.

6971c635af parport_serial: Add support for the WCH353 2S/1P multi-IO card
To allow parport_serial to handle the card the same PCI ids are blacklisted
in 8250_pci.c using the existing software blacklist mechanism.

The blacklist array is also renamed because it now covers this new use
case.

Since the two serial ports are auto-detected as XScale instead of 16550A
clones, we also add a quirk to 8250_pci.c to skip autodetection and set the
correct port type.
