Remove the following outbound related device tree properties:
brcm,pcie-ob-window-size
brcm,pcie-ob-oarr-size
The above two properties are a bit duplicated in functions. In addition,
the next generation iProc PCIe controller has outbound mapping window that
supports more than just two sizes, which cannot be properly supported by
these properties.

This patch adds specific compatible to support all the unversioned SCPI
protocols prior to v1.0 release. This will be applicable for all the
implementations using draft versions or modified versions of those
draft vesrions of SCPI protocol.

Since SCPI is a generic protocol and the bindings are intended to be
generic, we need to decouple all the platform specific binding details
out of the generic bindings.
This patch moves are the Juno platform specific details into a separate
binding document.

Jonathan writes:
Third set of IIO new device support, features and cleanup for the 4.10 cycle.
Includes Peter Rosin's interesting drivers for a comparator. First complex
use we have had with an analog front end made from discrete components.
Brian Masney's work on moving the tsl2583 driver out of staging also
feature extensively!
New Drivers
* DAC based on a digital potentiometer
- New driver for the use of a dpot as a DAC. Includes bindings and Axentia
entry in vendor prefixes.
* Envelope detector baed on DAC and a comparator including device tree
bindings.
Staging Graduation
* tsl2583.
Core new features
- Core provision for _available attributes. This one had been stalled for
a long time until Peter picked it up and ran with it!
- In kernel interface helpers to retrieve available info from channels.
Driver new features
* mcp4531
- Add range of available raw values (used for the dpot dac driver).
Driver cleanups and fixes for issues introduced
* ad7766
- Testing the wrong variable following devm_regulator_bulk_get introduced
with the driver earlier in this cycle.
* ad9832
- Fix a wrong ordering in the probe introduced in the previous set of
patches. A use before allocation bug.
* cros_ec_sensors
- Testing for an error in a u8 will never work.
* mpu3050
- Remove duplicate initializer for the module owner.
- Add missing i2c dependency.
- Inform the i2c mux core how it is used - step one in implifying device
tree bindings.
* st-sensors
- Get rid of large number of uninformative defines in favour of putting the
constants where they are relevant. It is clear what they are from where
they are used.
* tsl2583
- Fix unused function warning when CONFIG_PM disabled and remove the
ifdefs in favour of __maybe_unused.
- Refactor taos_chip_on to only read relevant registers.
- Make sure calibscale and integration time are being set.
- Verify chip is in ready to be used before calibration.
- Remove some repeated checks for chip status (it's protected by a mutex
so can't change until it's released)
- Change current state storage from a tristate enum to a boolean seeing as
only two values are actually used now.
- Drop a redundant write to the control regiser in taos_probe (it's a noop)
- Drop the FSF mailing address.
- Clean up logging to not use hard coded function names (use __func__
instead).
- Cleanup up variable and function name prefixes.
- Alignment of #define fixes.
- Fix comparison between signed and unsigned integer warnings.
- Add some newlines in favour of readability.
- Combine the two sysfs ABI docs that somehow ended up in different places.
- Fix multiline comment syntax.
- Move a code block to inside an else statement as it makes more sense there.
- Change tsl2583_als_calibrate to return 0 rather than a value nothing
reads.
- Drop some pointless brackets
- Don't assume 32bit unsigned int.
- Change to a per device instance lux table.
- Add missing tsl2583 to the list of supported devices in the intro comments.
- Improve commment on clearing of interrupts.
- Drop some uninformative comments.
- Drop a memset call that doesn't do anything useful any more.
- Don't initialize some return variables that are always set.
- Add Brian Masney as a module author after all these changes.
This adds the dt-binding documentation for the clock and reset unit
found on Rockchip rk1108 SoCs.

If the RAMOOPS_FLAG_FTRACE_PER_CPU flag is passed to ramoops pdata, split
the ftrace space into multiple zones depending on the number of CPUs.
This speeds up the performance of function tracing by about 280% in my
tests as we avoid the locking. The trade off being lesser space available
per CPU. Let the ramoops user decide which option they want based on pdata

The pin controller found in the Allwinner SoCs has support for interrupts
debouncing.
However, this is not done per-pin, preventing us from using the generic
pinconf binding for that, but per irq bank, which, depending on the SoC,
ranges from one to five.
Introduce a device-wide property to deal with this using a microsecond
resolution. We can re-use the per-pin input-debounce property for that, so
let's do it!

Some of the host drivers have the requirement of knowing whether the EP
would never train at some link speed at all. For instance, on some boards,
the link won't train at 5 GT/s but the host driver still sacrifice some
cycles to wait for the result of training at 5 GT/s as the host could
actually support 5 GT/s. So we could parse this new property and make the
host drivers be aware of these cases.
