Here is the big tty / serial driver pull request for 3.16-rc1.
A variety of different serial driver fixes and updates and additions,
nothing huge, and no real major core tty changes at all.
All have been in linux-next for a while.

On sam9x5, dedicated CTS (and RTS) pins are unusable together with the
LCDC, the EMAC, or the MMC because they share the same line.
Moreover, the USART controller doesn't handle DTR/DSR/DCD/RI signals,
so we have to control them via GPIO.
This patch permits to use GPIOs to control the CTS/RTS/DTR/DSR/DCD/RI
signals.

This passes the errata fix using a GPIO to control the RTS pin
on one of the AT91 chips to use gpiolib instead of the
AT91-specific interfaces. Also remove the reliance on
compile-time #defines and the cpu_* check and rely on the
platform passing down the proper GPIO pin through platform
data.
This is a prerequisite for getting rid of the local GPIO
implementation in the AT91 platform and move toward
multiplatform.
The patch also adds device tree support for getting the
RTS GPIO pin from the device tree on DT boot paths.

This patch will set the nand dma support in dts. Since we will not use
cpu_is_xxx() in nand driver. We needn't include the mach/cpu.h any more.

The nand driver use cpu_is_at32ap7000() macro for a workaround. For the
multi-platform support, we will remove this cpu_is_xxx() macro.
This patch adds a boolean variable need_reset_workaround in structure
atmel_nand_data. Using this variable we can remove cpu_is_at32ap7000() macro.

Modify both AT91 and AVR32 platforms.
Use 7 for it as the sam9260 or the sam9g25 have 7 of them DBGU included.

Commit bf4289cba0 ("ATMEL: fix nand ecc support") indicated that it
wanted to "Move platform data to a common header
include/linux/platform_data/atmel_nand.h" and the new header even had
re-include protectors with:
#ifndef __ATMEL_NAND_H__
However, the file that was added was simply called atmel.h
and this caused avr32 defconfig to fail with:
In file included from arch/avr32/boards/atstk1000/setup.c:22:
arch/avr32/mach-at32ap/include/mach/board.h:10:44: error: linux/platform_data/atmel_nand.h: No such file or directory

make[2]: *** [arch/avr32/boards/atstk1000/setup.o] Error 1
It seems the scope of the file contents will expand beyond
just nand, so ignore the original intention, and fix up the
users who reference the bad name with the _nand suffix.

So we can now choose for the board the ecc mode (ecc soft, soft bch, no ecc
and hardware).
Set ecc mode in the boards to soft as currently in the driver.
