Previous patches switched the ECAP and EPWM to use the new bindings.
These bindings explicitly adds the various required clocks via DT rather
than depending on hwmod.
Therefore, it is safe to remove the hwmod entries since they are no longer
needed.

Switch to a new ECAP and EPWM bindings that doesn't depend on hwmod to
provide the various required clocks.
For AM437 and AM335x, add the required clocks explicitly to DT. The
hwmod entries for ECAP and EPWM will be removed and this will prevent
anything from breaking.

This patch adds support for Broadcom's BCM53xx switch family, also known
as RoboSwitch. Some of these switches are ubiquituous, found in home
routers, Wi-Fi routers, DSL and cable modem gateways and other
networking related products.
This drivers adds the library driver (b53_common.c) as well as a few bus
glue drivers for MDIO, SPI, Switch Register Access Block (SRAB) and
memory-mapped I/O into a SoC's address space (Broadcom BCM63xx/33xx).
Basic operations are supported to bring the Layer 1/2 up and running,
but not much more at this point, subsequent patches add the remaining

Jonathan writes:
First round of IIO new device support, features and cleanups for the 4.8 cycle.
New device support
* ads1015
- add ads1115 support
* bma220 accelerometer
- new driver
- triggered buffer support.
* bmc150
- add bmm150 support.
* bmp280
- bme280 support with addition of humidity channel.
* max5487 potentiometer
- new driver
* MMA7660FC accelerometer.
- New driver
* st-pressure
- support for the lps22hb
* loop trigger.
- This one is *nasty* but we have real applications (parrot drones) where
it is useful. The trigger basically spins as hard as it can firing off
a new trigger each time all triggered devices come back to say they are
done. It doesn't hang a machine even when doing it on a dummy driver.
A lot nicer than having this implemented within lots of device drivers
anyway.
Core stuff
* Add support to create IIO devices via configfs (similar to we did for
triggers a while back) + docs.
* New channel types
- IIO_ELECTRICAL_CONDUCTIVITY
* Couple of MAINTAINERS patches to list the device tree bindings.
* Make trigger ops structure non optional (comment fix). It hasn't been for
an awful long time, but that's not what the description said.
New features
* ak8975
- support adapters that are limited to byte data only by allowing the
emulated block read i2c function that was recently introduced.
* atlas-ph
- support atlas-ec (electrical conductivity sensor)
* bmi160
- add available frequency and scale attributes to make the driver
more user friendly (and avoid having to read the datasheet to know
what will work).
* dummy
- move creation to configfs interface. It's not real hardware so we
are not that worried about the ABI breakage ;)
* mma8452
- oversampling ration support
* nau7802
- expose available gains to make life easier for userspace.
* st-sensors
- allow use of emulation for SMBus block reads as all the st parts support
it.
* ti-ads1015
- list datasheet names to allow their use by inkernel consumers.
* Various module alias additions to help auto probing. Drop one redundant one
as well.
Cleanups
* ad7266, ad7476, ad7887, ad7923, ad799x
- use direct mode claim function rather than open coding it during sensor
read (prevents switching on buffers mid read).
* ad7793, ad7791
- use direct mode claim to prevent frequency changes when buffers running.
* afe440x - These are ABI breaking but the driver requires custom userspace
code to do anything useful anyway and that is still being written and under
control of TI. Ultimately we may have other libraries to do pulse
oximetry with these devices but we aren't aware of any yet.
- kernel-doc format fixes
- drop ifdef fun around of_match_ptr - it's not worth the mess to save
a tiny amount of space.
- drop some unnecessary register initializations.
- drop the weird locked gain modes as they gain us nothing (can just set
all gains separately).
- remove handling of offset attributes seeing as no channels actually have
them (oops)
- Drop the LED3 input channel as it's an alias for ALED2.
- *big one* remove channel names - an experiment that turned out to not
make sense - see patch for details.
- use regmap fields to clean up code.
- tie the tia gain stages to appropriate channels in the ABI as that is
what they really effect. Same with the LED currents.
- cleanout some unused defines and fix a missnamed one.
* atlas-ph
- reorganise to allow support of other similar parts.
* bmc150
- document supported chips in kconfig help.
* jsa1212
- drop an unneeded i2c functionality check for functionality the driver
doesn't use.
* mxs-lradc
- simply touch screen registration code.
- remove the touch screen unregister as all devm based now.
- disable only those channels that are masked in hardware stop (others
are already dealt with elsewhere)
* st-sensors
- unexport st_sensors_get_buffer_element as nothing outside the st-sensors
core driver uses it.
- fix handling of failure to start up regulators.
* tpl0102
- drop an i2c functionality test for features that aren't needed.
* ti-am335x
- use variable name rather than type in sizeof for clarity.
- use SIMPLE_DEV_PM_OPS helper macro to tidy up a bit.
Tools
* Add install / uninstall to makefile. Someone cares, so presumably
some people will find it useful!
* generic_buffer
- rename to iio_generic_buffer to line up with other tools.
- handle cleanup when receiving signals
- Add a --device-num option and a --trigger-num option rather than
relying on naming which doesn't work if you have two of the same part.

The axp20x pmics have 2 power inputs, one called ACIN which is intended
for to be supplied via a powerbarrel on the board and one called VBUS
which is intended to be supplied via an otg connector.
In the VBUS case the pmic needs to know if the board is supplying power
to the otg connector, because then it should not take any power from
its VBUS pin. The axp209 pmic has a N_VBUSEN input pin via which the
board can signal to the pmic whether the board is supplying power to the
otg connector or not.
On the axp221/axp223 this pin can alternatively be used as an output
which controls an external regulator which (optionally) supplies
power to the otg connector from the board. When the pin is used as
output it is called DRIVEVBUS in the datasheet.
This commit adds support for the DRIVEVBUS pin as an extra pmic
controlled regulator. Since this is optional a new x-powers,drivebus dt
property is added. When this is present the misc-control register is
written to change the N_VBUSEN input pin to DRIVEVBUS output pin mode and
the extra drivebus regulator is registered with the regulator subsystem.

The EBI (External Bus Interface) is used to access external peripherals
(NOR, SRAM, NAND, and other specific devices like ethernet controllers).
Each device is assigned a CS line and an address range and can have its
own configuration (timings, access mode, bus width, ...).
This driver provides a generic DT binding to configure a device according
to its requirements.
For specific device controllers (like the NAND one) the SMC timings
should be configured by the controller driver through the matrix and smc
syscon regmaps.

The Hardkernel's Odroid XU board was first design with big.LITTLE SoC
from Samsung: the Exynos5410. Details:
1. Exynos5410 octa-core (A15+A7, however as of now only one cluster is
enabled),
2. 2 GB DDR3 RAM,
3. PowerVR SGX544MP3 GPU (not enabled in DTS),
4. USB 3.0 Host x 1, USB 3.0 OTG x 1, USB 2.0 Host x 4,
5. HDMI 1.4a, MIPI DSI and Display Port (Display Port not on all of
revisions though),
6. eMMC 4.5 and microSD slots.
Comparing this board to Odroid XU3 (more popular), the differences are:
1. Exynos5410 instead of 5422,
2. MIPI DSI LCD connector,
3. Main PMIC: Maxim 77802 instead of S2MPS11,
4. USB3503+LAN9730 instead of integrated LAN9514,
5. eMMC 4.5 instead of eMMC 5.0,
This patch adds initial support for the XU board with working basic
functions, eMMC/SD and USB (including attached ethernet adapter).

This patch adds support for the direct access mode to the Orion SPI
driver which is used on the Marvell Armada based SoCs. In this direct
mode, all data written to (or read from) a specifically mapped MBus
window (linked to one SPI chip-select on one of the SPI controllers)
will be transferred directly to the SPI bus. Without the need to control
the SPI registers in between. This can improve the SPI transfer rate in
such cases.
Both, direct-read and -write mode are supported. But only the write
mode has been tested. This mode especially benefits from the SPI direct
mode, as the data bytes are written head-to-head to the SPI bus,
without any additional addresses.
One use-case for this direct write mode is, programming a FPGA bitstream
image into the FPGA connected to the SPI bus at maximum speed.
This mode is described in chapter "22.5.2 Direct Write to SPI" in the
Marvell Armada XP Functional Spec Datasheet.
