Pretty much any node can have a status property, so it doesn't need to
be in examples.
Converted with the following command and removed examples with SoC and
board specific splits:

The RTC can output its 32kHz clock outside of the SoC, for example to clock
a WiFi chip.
Create a new clock that other devices will be able to retrieve, while
maintaining the DT stability by providing a default name for that clock if
clock-output-names doesn't list one.

Commit 8b44f5be20fd ("ARM: dts: armada: replace isil,irq2-can-wakeup-machine with wakeup-source property")
removed the last usage of "isil,irq2-can-wakeup-machine" almost
two years ago. So I think we can get rid of supporting this

The Armada 7K/8K use the same RTC IP than the Armada 38x. However the SOC
integration differs in 2 points:
- MBUS bridge timing initialization
- IRQ configuration at SoC level
Moreover the Armada 7K/8K have an issue preventing to get the interrupt
from alarm 1. This commit allows to use alarm 2 for these A7K/8K but to
still use alarm 1 for the Armada 38x.

There are currently two broken bindings descriptions for RTC:
maxim,ds3231.txt
pcf8563.txt
They broke because of a improper RST documentation conversion with
commit 8c27ceff3604b2 ("docs: fix locations of several documents that got
moved") and now reference to a non-existing file:
Documentation/devicetree/bindings/i2c/trivial-admin-guide/devices.rst
However, the original reference to i2c/trivial-devices should have never
been made in the first place.
This change fixes this issue by replacing with correct descriptions.

The RTC controls the input source of the main 32kHz oscillator in the
system, feeding it to the clock unit too.
By default, this is using an internal, very inaccurate (+/- 30%)
oscillator with a divider to make it roughly around 32kHz. This is however
quite impractical for the RTC, since our time will not be tracked properly.
Since this oscillator is an input of the main clock unit, and since that
clock unit will be probed using CLK_OF_DECLARE, we have to use it as well,
leading to a two stage probe: one to enable the clock, the other one to
enable the RTC.
There is also a slight change in the binding that is required (and should
have been from the beginning), since we'll need a phandle to the external
oscillator used on that board. We support the old binding by not allowing
to switch to the external oscillator and only using the internal one (which
was the previous behaviour) in the case where we're missing that phandle.

possible to enable ext_wakeup and set it's polarity, depending on board

to recover from RTC-only power states correctly.

This patch marks all the reference to the legacy wakeup bindings
and replaces them with the standard "wakeup-source" property.
All these legacy property are also listed under a separate section in
the generic wakeup-source binding document.

Pull i2c updates from Wolfram Sang:
"Features:
- new drivers: Renesas EMEV2, register based MUX, NXP LPC2xxx
- core: scans DT and assigns wakeup interrupts. no driver changes needed.
- core: some refcouting issues fixed and better API for that
- core: new helper function for best effort block read emulation
- slave framework: proper DT bindings and userspace instantiation
- some bigger work for xiic, pxa, omap drivers
.. and quite a number of smaller driver fixes, cleanups, improvements"

rtc can either be supplied from internal 32k clock or external crystal
generated 32k clock. Internal clock is SOC specific and the external
clock is board dependent. Adding the corresponding nodes.

Pull ARM DT updates from Olof Johansson:
"Ladies and gentlemen, we proudly announce to you the latest branch of
ARM device tree contents for the mainline kernel. Come and see, come
and see!
No less than twentythree thousand lines of additions! Just imagine the
joy you will have of using your mainline kernel on newly supported
hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or
UniPhier hardware!
For those of you feeling less adventurous, added hardware support on
platforms such as TI DM814x and Gumstix Overo platforms might be more
of your liking.
We've got something for everyone here!
Ahem. Cough. So, anyway...
This is the usual large batch of DT updates. Lots and lots of smaller
changes, some of the larger ones to point out are:
- Rockchip veyron (Chromebook) support, as well as several other new boards
- DRM support on Atmel AT91SAM9N12EK
- USB additions on some Allwinner platforms
- Mediatek MT6580 support
- Freescale i.MX6UL support
- cleanups for Renesas shmobile platforms
- lots of added devices on LPC18xx
- lots of added devices and boards on UniPhier
There's also some dependent code added here, in particular some
branches that are primarily merged through the clock tree"
