us to use generic parser later on. Note that the driver supports
handling the legacy binding also with no #pinctrl-cells so these

usb: patches for v4.10 merge window
One big merge this time with a total of 166 non-merge commits.
Most of the work, by far, is on dwc2 this time (68.2%) with dwc3 a far
second (22.5%). The remaining 9.3% are scattered on gadget drivers.
The most important changes for dwc2 are the peripheral side DMA support
implemented by Synopsys folks and support for the new IOT dwc2
compatible core from Synopsys.
In dwc3 land we have support for high-bandwidth, high-speed isochronous
endpoints and some non-critical fixes for large scatter lists.
Apart from these, we have our usual set of cleanups, non-critical fixes,
etc.
The BPMP implements some services which must be represented by separate
nodes. For example, it can provide access to certain I2C controllers,
and the I2C bindings represent each I2C controller as a device tree
node. Update the binding to describe how the BPMP supports this.

The Boot and Power Management Processor (BPMP) is a co-processor found
in Tegra SoCs. It is designed to handle the early stages of the boot
process as well as to offload power management tasks (such as clocks,
resets, powergates, ...).
The binding document defines the resources that are used by the BPMP
firmware, which implements the interprocessor communication (IPC)
between the CPU and the BPMP.

This patch adds support for the "amcc,usb-otg" device
which is found in the PowerPC Canyonlands' dts.
The device definition was added by:
commit c89b3458d8 ("powerpc/44x: Add USB DWC DTS entry to Canyonlands
board")
but without any driver support as the dwc2 driver wasn't available at
that time.
Note: The system can't use the generic "snps,dwc2" compatible
because of the special ahbcfg configuration. The default
GAHBCFG_HBSTLEN_INCR4 of snps,dwc2 can cause a system hang
when the USB and SATA is used concurrently.

The Aspeed SoCs have two BT interfaces : one is IPMI compliant and the
other is H8S/2168 compliant.
The current ipmi/bt-bmc driver implements the IPMI version and we
should reflect its nature in the compatible node name using
'aspeed,ast2400-ibt-bmc' instead of 'aspeed,ast2400-bt-bmc'. The
latter should be used for a H8S interface driver if it is implemented

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.
