HIRD threshold should be configurable by different platforms.
From DesignWare databook:
When HIRD_Threshold[4] is set to 1b1 and HIRD value is greater than or
equal to the value in HIRD_Threshold[3:0], dwc3 asserts output signals
utmi_l1_suspend_n to put PHY into Deep Low-Power mode in L1.
When HIRD_Threshold[4] is set to 1b0 or the HIRD value is less than
HIRD_Threshold[3:0], dwc3 asserts output signals utmi_sleep_n on L1.

to send NYET response threshold based on the BESL value received in the LPM
token, and the threhold is configurable for each soc platform.
This patch adds an entry that soc platform is able to define the lpm
capacity with their own device tree or bus glue layer.

Pull squashfs update from Phillip Lougher:
"These patches optionally add LZ4 compression support to Squashfs.
LZ4 is a lightweight compression algorithm which can be used on
embedded systems to reduce CPU and memory overhead (in comparison to
the standard zlib compression).
These patches add the wrapper code to allow Squashfs to use the
existing LZ4 decompression code, and the necessary configuration
option"

Pull take two of the GPIO updates:
"Same stuff as last time, now with a fixup patch for the previous
compile error plus I ran a few extra rounds of compile-testing.
This is the bulk of GPIO changes for the v3.19 series:
- A new API that allows setting more than one GPIO at the time. This
is implemented for the new descriptor-based API only and makes it
possible to e.g. toggle a clock and data line at the same time, if
the hardware can do this with a single register write. Both
consumers and drivers need new calls, and the core will fall back
to driving individual lines where needed. Implemented for the
MPC8xxx driver initially
- Patched the mdio-mux-gpio and the serial mctrl driver that drives
modems to use the new multiple-setting API to set several signals
simultaneously
- Get rid of the global GPIO descriptor array, and instead allocate
descriptors dynamically for each GPIO on a certain GPIO chip. This
moves us closer to getting rid of the limitation of using the
global, static GPIO numberspace
- New driver and device tree bindings for 74xx ICs
- New driver and device tree bindings for the VF610 Vybrid
- Support the RCAR r8a7793 and r8a7794
- Guidelines for GPIO device tree bindings trying to get things a bit
more strict with the advent of combined device properties
- Suspend/resume support for the MVEBU driver
- A slew of minor fixes and improvements"

Introduce new functions gpiod_set_array & gpiod_set_raw_array to the consumer
interface which allow setting multiple outputs with just one function call.
Also add an optional set_multiple function to the driver interface. Without an
implementation of that function in the chip driver outputs are set
sequentially.
Implementing the set_multiple function in a chip driver allows for:
- Improved performance for certain use cases. The original motivation for this
was the task of configuring an FPGA. In that specific case, where 9 GPIO
lines have to be set many times, configuration time goes down from 48 s to
20 s when using the new function.
- Simultaneous glitch-free setting of multiple pins on any kind of parallel
bus attached to GPIOs provided they all reside on the same chip and bank.
Limitations:
Performance is only improved for normal high-low outputs. Open drain and
open source outputs are always set separately from each other. Those kinds
of outputs could probably be accelerated in a similar way if we could
forgo the error checking when setting GPIO directions.
Change log:
v6: - rebase on current linux-gpio devel branch
v5: - check can_sleep property per chip
- remove superfluous checks
- supplement documentation
v4: - add gpiod_set_array function for setting logical values
- change interface of the set_multiple driver function to use
unsigned long as type for the bit fields
- use generic bitops (which also use unsigned long for bit fields)
- do not use ARCH_NR_GPIOS any more
v3: - add documentation
- change commit message
v2: - use descriptor interface
- allow arbitrary groups of GPIOs spanning multiple chips

Now that ACPI supports named GPIO properties, either through ACPI 5.1 or
the per-driver ACPI GPIO mappings, we can be more narrow about the way
GPIOs should be specified in Device Tree bindings.
This patch updates the GPIO DT bindings documentation to highlight the
following rules for new GPIO bindings:
- All new bindings must have a meaningful name (e.g. the "gpios"
property must not be used)
- The only suffix allowed is "-gpios", no matter the number of
descriptors in the property
- GPIOs can only be grouped under the same property when they serve the
same purpose, a case that should remain exceptional (e.g. bit-banged
data lines).

The Vybrid SoC device tree (vf610.dtsi) used this bindings since
its initial commit in May 2013. However, a proper gpiolib driver
was missing so far. With the addition of the gpiolib driver,
the bindings proved to be useful and complete, hence a good time
to add the documentation.

Pull i2c updates from Wolfram Sang:
"For 3.19, the I2C subsystem has to offer special candy this time.
Right in time for Christmas :)
- I2C slave framework: finally, a generic mechanism for Linux being
an I2C slave (if the bus driver supports that). Docs are still
missing but will come later this cycle, the code is good enough to
go.
- I2C muxes represent their topology in sysfs much more detailed.
This will help users to navigate around much easier.
- irq population of i2c clients is now done at probe time, not device
creation time, to have better support for deferred probing.
- new drivers for Imagination SCB, Amlogic Meson
- DMA support added for Freescale IMX, Renesas SHMobile
- slightly bigger driver updates to OMAP, i801, AT91, and rk3x
(mostly quirk handling, timing updates, and using better kernel
interfaces)
- eeprom driver can now write with byte-access (very slow, but OK to
have)
- and the bunch of smaller fixes, cleanups, ID updates..."

In (6468276 i2c: designware: make SCL and SDA falling time
configurable) new device tree properties were added for setting the
falling time of SDA and SCL. The device tree bindings doc had a typo
in it: it forgot the "-ns" suffix for both properies in the prose of
the bindings.
I assume this is a typo because:
* The source code includes the "-ns"
* The example in the bindings includes the "-ns".
Fix the typo.

callbacks. Update the I2C device driver guides to reflect this.

Make it possible to transfer i2c message buffers via DMA.
Start/Stop/Sending_Slave_Address is still handled using the old state
machine, it is sending the actual data that is done via DMA. This is
least intrusive and allows us to work with the message buffers directly
instead of preparing a custom buffer which involves copying the data
around.

Pull block driver core update from Jens Axboe:
"This is the pull request for the core block IO changes for 3.19. Not
a huge round this time, mostly lots of little good fixes:
- Fix a bug in sysfs blktrace interface causing a NULL pointer
dereference, when enabled/disabled through that API. From Arianna
Avanzini.
- Various updates/fixes/improvements for blk-mq:
- A set of updates from Bart, mostly fixing buts in the tag
handling.
- Cleanup/code consolidation from Christoph.
- Extend queue_rq API to be able to handle batching issues of IO
requests. NVMe will utilize this shortly. From me.
- A few tag and request handling updates from me.
- Cleanup of the preempt handling for running queues from Paolo.
- Prevent running of unmapped hardware queues from Ming Lei.
- Move the kdump memory limiting check to be in the correct
location, from Shaohua.
- Initialize all software queues at init time from Takashi. This
prevents a kobject warning when CPUs are brought online that
weren't online when a queue was registered.
- Single writeback fix for I_DIRTY clearing from Tejun. Queued with
the core IO changes, since it's just a single fix.
- Version X of the __bio_add_page() segment addition retry from
Maurizio. Hope the Xth time is the charm.
- Documentation fixup for IO scheduler merging from Jan.
- Introduce (and use) generic IO stat accounting helpers for non-rq
drivers, from Gu Zheng.
- Kill off artificial limiting of max sectors in a request from
Christoph"

* a general explanation
* a discussion of the memory in-place operation
* the description of the message digest API
* the description of the symmetric cipher API
The documentation refers to libkcapi as a working example on how to use
the kernel crypto API from user space.
