48a10cdfc0 drivers/serial/ucc_uart.c: Add of_node_put to avoid memory leak
Add a call to of_node_put in the error handling code following a call to
of_find_compatible_node or of_find_node_by_type.

This patch also substantially reorganizes the error handling code in the
function, to that it is possible first to jump to code that frees qe_port
and then to jump to code that also puts np.

The semantic match that finds this problem is as follows:

29772c4e28 ARM: 6764/1: pl011: factor out FIFO to TTY code
This piece of code was just slightly different between the DMA

256 character either, so factor this out in its own function and
use for both DMA and PIO mode.

Tested on Ux500 and U300.

This adds an optional RX DMA codepath for the devices that

pulling single bytes.

Includes portions of code written by Russell King during
a PL08x hacking session.

This has been tested on U300 and Ux500.

5504623785 serial: msm_serial_hs: Add MSM high speed UART driver
This driver supports UART-DM HW on MSM platforms. It uses the on
chip DMA to drive data transfers and has optional support for UART
power management independent of Linux suspend/resume and wakeup
from Rx.

The driver was originally developed by Google. It is functionally
equivalent to the version available at:
http://android.git.kernel.org/?p=kernel/experimental.git
the differences being:
1) Remove wakelocks and change unsupported DMA API.
2) Replace clock selection register codes by macros.
3) Fix checkpatch errors and add inline documentation.
4) Add runtime PM hooks for active power state transitions.
5) Handle error path and cleanup resources if required.

36003386f8 serial: sh-sci: fix deadlock when resuming from S3 sleep
S3 sleep invokes the shutdown callback of the sh-sci driver, which
suspends the clocks until they are reactivated by a call to startup.
However, before the latter is invoked, sci_set_termios may be called on
the port by uart_resume_port. In such cases it will endlessly wait for
the TEND bit to raise, which will never happen since the clocks are
disabled.

This patch ensures that clocks are enabled when ports registers are
manipulated within sci_set_termios.

Also change the driver to use only one platform device per port.

f023eab379 serial: mfd: add a module parameter for setting each port's working mode
The three identical uart ports can work either in DMA or PIO mode. Adding such
a module parameter "hsu_dma_enable" will enable user to chose working modes for
each port. If the mfd driver is built in kernel, adding a "mfd.hsu_dma_enable=x"
in kernel command line has the same effect.

60b33c133c tiocmget: kill off the passing of the struct file
We don't actually need this and it causes problems for internal use of
this functionality. Currently there is a single use of the FILE * pointer.
That is the serial core which uses it to check tty_hung_up_p. However if
that is true then IO_ERROR is also already set so the check may be removed.

2780ad42f5 tty: serial: altera_uart: Use port->regshift to store bus shift
Use the regshift member of struct uart_port to store the address stride
from platform data. This way we can save one dereference per call of
altera_uart_readl and altera_uart_writel.

This also allows us to use the driver without platform data, which is
needed for device tree support in the Nios2 port.
