* Dyna-Image al3320a ambient light sensor driver
* Bosh bmi055 gyroscope part driver (accelerometer part supported by bmc150)
* isl29018 - add support for isl29023 and isl29035

* bmc150 - additional part support (BMI055 accelerometer part, BMA255,
BMA222E, BMA250E and BMA280). Different resolutions but otherwise similar
parts.
* bma180 - add BMA250 (note different from the BMA250E support above despite
the naming). A lot of driver reworking lead up to this - described below.
New features
* kxcjk1013 - add threshold event support.
* rockchip - document DT bindings.
* isl29018 - ACPI support
* bma180 - enable use without IRQ
Cleanups
* Tree wide - drop owner field assignment if using the module_platform_driver
helper as that assigns it anyway.
* kxcjk1013 - drop a redundant assignment of the current range and fix a
a defined but not used warning.
* inv_mpu6050 - Remove an unnecessary cast form a void pointer.
* rockchip - drop and unused variable.
* at91_adc - make a local function static.
* st-sensors-core - correctly handle an error in setting in
st_sensors_set_drdy_int_pin
* isl29018 - typo fix
* bmc150 - fix incorrect scale value for 16G range (Driver new this cycle)
* bmc150 - fix issues when CONFIG_PM_RUNTIME not set (Driver new this cycle)
* ad7606 - line length tidy up.
* bmg160 - set power state only if PM_RUNTIME is defined.
* ak8975 - fix some unnecessary casting between char * and const char *
* bma180 - prefix remaining bits and bobs with bma180_ and ensure consistent.
- use a bool instead of an int for state (as its either on or off).
- expose the temperature channel
- statically allocate buffers to avoid need for update_scan_mode
callback.
- refactor to allow futher chip variants including support for part
specific config and disable code + different resolutions.

vfs: avoid non-forwarding large load after small store in path lookup
The performance regression that Josef Bacik reported in the pathname
lookup (see commit
99d263d4c5b2 "vfs: fix bad hashing of dentries") made
me look at performance stability of the dcache code, just to verify that
the problem was actually fixed. That turned up a few other problems in
this area.
There are a few cases where we exit RCU lookup mode and go to the slow
serializing case when we shouldn't, Al has fixed those and they'll come
in with the next VFS pull.
But my performance verification also shows that link_path_walk() turns
out to have a very unfortunate 32-bit store of the length and hash of
the name we look up, followed by a 64-bit read of the combined hash_len
field. That screws up the processor store to load forwarding, causing
an unnecessary hickup in this critical routine.
It's caused by the ugly calling convention for the "hash_name()"
function, and easily fixed by just making hash_name() fill in the whole
'struct qstr' rather than passing it a pointer to just the hash value.
With that, the profile for this function looks much smoother.

When CONFIG_PM_RUNTIME is not defined and bmg160 tries to power

usb: dwc2: make the scheduler handle excessive NAKs better
I'm seeing problems with a d-link dwcl-g122 wifi dongle that
someone sent me. There are reports of other wifi dongles with the
same/similar problem. The devices appear to be NAKing to the point
of confusing the dwc2 driver completely.
The attached patch helps with my d-link dwl-g122 - it's adapted
from the Raspberry Pi dwc_otg driver, which is a modified version
of the Synopsys vendor driver. The error recovery is still valid
after the patch, I think.

The NTB translate register must have the value to be BAR size aligned.
This alignment check make sure that the DMA memory allocated has the
proper alignment. Another requirement for NTB to function properly with
