5c7404bb30 dt-bindings: Change maintainer address
While my email address has changed for a while, all the schemas I
contributed still have the old one unfortunately. Update it.

454f5d9da1 dt-bindings: Remove FIXME in yaml bindings
Some binding that were introduced early on got a comment to enable
additionalProperties, but we couldn't due to the generic properties being
reported as errors.

The way we're dealing with this now is to use the draft-08's
unevaluatedProperties (even though the tools doesn't do anything with it
yet).

Let's convert those old bindings to it.

b644257f0e dt-bindings: i2c: add bindings for i2c analog and digital filter
Some i2c controllers have a built-in digital or analog filter.
This is specifically required depending on the hardware PCB/board.
Some controllers also allow specifying the maximum width of the
spikes that can be filtered for digital filter. The width length can be
specified in nanoseconds.
Analog filters can be configured to have a cutoff frequency (low-pass filter).
This frequency can be specified in Hz.
Added an optional property for such types of analog filters.

7c672abc12 It's a somewhat calmer cycle for docs this time, as the churn of the mass
RST conversion is happily mostly behind us.
 
  - A new document on reproducible builds.
 
  - We finally got around to zapping the documentation for hardware support
    that was removed in 2004; one doesn't want to rush these things.
 
  - The usual assortment of fixes, typo corrections, etc.
 
 You'll still find a handful of annoying conflicts against other trees,
 mostly tied to the last RST conversions; resolutions are straightforward
 and the linux-next ones are good.

0038617132 dt-bindings: i2c: sun6i-p2wi: Fix the binding example
Even though the binding claims that the frequency can go up to 6MHz, the
common i2c binding sets a limit at 3MHz, which then triggers a warning.

Since the only SoC that uses that bus uses a frequency of 100kHz, and that
this bus hasn't been found in an SoC for something like 5 years, let's just
fix the example to have a frequency within the acceptable range for i2c.

7ea651ec39 dt-bindings: i2c: extend existing opencore bindings
Reformatted compatibility strings to one valid combination on
each line.
Add FU540-C000 specific device tree bindings to already available
i2-ocores file. This device is available on
HiFive Unleashed Rev A00 board. Move interrupt under optional
property list as this can be optional.

The FU540-C000 SoC from sifive, has an Opencore's I2C block
reimplementation.

The DT compatibility string for this IP is present in HDL and available at.

Mainly some pca954x work, i.e. removal of unused platform data support
and added support for sysfs interface for manipulating/examining the
idle state. And then a mechanical cocci-style patch.

Update the binding document to make the 'interrupts' property optional.
For certain revisions of the I2C controller (e.g., iProc NIC I2C), I2C
interrupt is unwired to the interrupt controller. In such case, this
'interrupts' property should be left unspecified, and driver will fall
back to polling mode

Pull Devicetree updates from Rob Herring:
 "The biggest highlight here is the start of using json-schema for DT
  bindings. Being able to validate bindings has been discussed for years
  with little progress.

   - Initial support for DT bindings using json-schema language. This is
     the start of converting DT bindings from free-form text to a
     structured format.

   - Reworking of initrd address initialization. This moves to using the
     phys address instead of virt addr in the DT parsing code. This
     rework was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary
     rebuilding of lots of files.

   - Fix stale phandle entries in phandle cache

   - DT overlay validation improvements. This exposed several memory
     leak bugs which have been fixed.

   - Use node name and device_type helper functions in DT code

   - Last remaining conversions to using %pOFn printk specifier instead
     of device_node.name directly

   - Create new common RTC binding doc and move all trivial RTC devices
     out of trivial-devices.txt.

   - New bindings for Freescale MAG3110 magnetometer, Cadence Sierra
     PHY, and Xen shared memory

   - Update dtc to upstream version v1.4.7-57-gf267e674d145"
