The sama5d2 SoC has Synchronous Serial Controller which provides
synchronous communication link with external devices.
It's generally used in audio and telecom applications such as
I2S, Short Frame Sync, Long Frame Sync.

The sama5d2 SoC has a second DMA controller and can be used just like DMA0.
By default both DMA controllers are configured as "Secure" in
MATRIX_SPSELR so we can use whichever we want in a "single Secure World"
configuration.
Surprisingly the DMA1 has a lower address than DMA0. To avoid confusion
place it after DMA0 node anyway.

Device tree contents continue to be the largest branches we submit. This
time around, some of the contents worth pointing out is:
- New SoC platforms:
- Freescale i.MX 7Solo
- Broadcom BCM23550
- Cirrus Logic EP7209 and EP7211 (clps711x platforms)_
- Hisilicon HI3519
- Renesas R8A7792
Some of the other delta that is sticking out, line-count wise:
- Exynos moves of IP blocks under an SoC bus, which causes a large delta due
to indentation changes
- A new Tegra K1 board: Apalis
- A bunch of small updates to many Allwinner platforms; new hardware support,
some cleanup, etc.

which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
changesets, 450 files changed, 23340 insertions, 5216 deletions.
The three platforms that are added with the "soc" branch are here as well,
and we add some related machine files:
- For Aspeed AST2400/AST2500, we get the evaluation platform and
the Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC

is added as the only platform at the moment.
- For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7)
are supported
On the ARM Realview development platform, we now support all machines
with device tree, previously only the board files were supported, which
in turn will likely be removed soon.

An error in documentation of the NAND Flash Controller (NFC) led to choose
another compatibility string for sama5d2 with an impact on the NAND flash
ready/busy information. It was producing the error message:
atmel_nand 80000000.nand: Time out to wait for interrupt: 0x08000000
and had an impact on performance.
So, switch back to the classical "atmel,sama5d3-nfc" compatibility string for
this SoC which gives the proper ready/busy bit information. The NAND flash
driver will be updated to remove the support for this different
implementation.

As usual, this is the massive branch we have for each release. Lots of
various updates and additions of hardware descriptions on existing hardware,
as well as the usual additions of new boards and SoCs.
This is also the first release where we've started mixing 64- and 32-bit
DT updates in one branch.
(Specific details on what's actually here and new is pretty easy to tell
from the diffstat, so there's little point in duplicating listing it here.)

Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM DT updates from Olof Johansson:
"As usual, this is the massive branch we have for each release. Lots
of various updates and additions of hardware descriptions on existing
hardware, as well as the usual additions of new boards and SoCs.
This is also the first release where we've started mixing 64- and
32-bit DT updates in one branch.
(Specific details on what's actually here and new is pretty easy to
tell from the diffstat, so there's little point in duplicating listing
it here)"

The PMC is not only used to drive the clocks but also has some registers
related to other functions. One of those is for example the USB gadget
bias.
Using a syscon allows to properly separate those functions.

The watchdog, the reset controller, the RTC, the shutdown controller, the
timer counters and the LCD PWM need the slow clock, add it to the currently
defined nodes.

Only the basic support for this new Atmel Cortex-A5 SoC. A subset of the
peripherals is setup to allow booting.
IRQ, clocks, USB, crypto, timers, rtc, ethernet, spi/i2c and
uart/usart peripheral nodes are added.
