"The most notable item is addition of support for Synaptics RMI4
protocol which is native protocol for all current Synaptics devices
(touchscreens, touchpads). In later releases we'll switch devices
using HID and PS/2 protocol emulation to RMI4.
You will also get:
- BYD PS/2 touchpad protocol support for psmouse
- MELFAS MIP4 Touchscreen driver
- rotary encoder was moved away from legacy platform data and to
generic device properties API, devm_* API, and can now handle
encoders using more than 2 GPIOs
- Cypress touchpad driver was switched to devm_* API and device
properties
- other assorted driver fixes"

Merge with Linux 4.5 to get PROPERTY_ENTRY_INTEGER() that is needed to
fix pxa/raumfeld rotary encoder properties.
ICP DAS LP-8841 contains a DS-1302 RTC. This driver provides an SPI
master which makes the RTC usable. The driver is not supposed to work
with anything else.
The driver uses the standard MicroWire half-duplex transfer timing.
Master output is set on low clock and sensed by the RTC on the rising
edge. Master input is set by the RTC on the trailing edge and is sensed
by the master on low clock.

Add the devicetree bindings documentation for the Analog Devices
axi-spi-engine SPI master peripheral. This is a soft-peripheral used in
FPGAs.
The external interfaces of the peripheral are:
* A memory mapped register map which is used to configure the
peripheral.
* One interrupt.
* Two clocks, one for the memory mapped register interface and one
for the SPI bus.
* A SPI master interface to which the slave devices are connected.
These interfaces are described by the devicetree bindings accordingly.

As usual, the bulk of this release is again DT file contents.
There's a huge number of changes here, and it's challenging to give a crisp
overview of just what is in here. To start with:
New boards:
- TI-based DM3730 from LogicPD (Torpedo)
- Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
- Raspberry Pi 2 DT files
- Watchdog on Meson8b
- Veyron-mickey (ASUS Chromebit) DTS
- Rockchip rk3228 SoC and eval board
- Sigma Designs Tango4
Improvements:
- Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
- Misc new devices for Rockchip rk3036 and rk3288
- Allwinner updates for misc SoCs and systems
... and a _large_ number of other changes across the field. Devices
added to SoC DTSI and board DTS files for a number of SoC vendors, new
product boards on already-supported SoCs, cleanups and refactorings of
existing DTS/DTSI files and a bunch of other changes.

- add new property "atmel,fifo-size"
- change "cs-gpios" to optional for SPI controller version >= 2.
Please be aware that the VERSION register can not be used to guess the
size of FIFOs. Indeed, for a given hardware version, the SPI controller
can be integrated on Atmel SoCs with different FIFO sizes. Also the
"atmel,fifo-size" property is optional as older SPI controllers don't
embed FIFO at all.
Besides, the FIFO size can not be read or guessed from other registers:
When designing the FIFO feature, no dedicated registers were added to
store this size. Unused spaces in the I/O register range are limited and
better reserved for future usages. Instead, the FIFO size of each
peripheral is documented in the programmer datasheet.
Finally, on a given SoC, there can be several instances of the SPI
controller with different FIFO sizes. This explain why we'd rather use a
dedicated DT property than use the "compatible" property.
For instance, sama5d2x SoCs come with some SPI controllers, the ones
inside Flexcoms, integrating 32 data FIFOs whereas other SPI controllers
use 16 data FIFOs. All these SPI controllers share the same IP version.

The commit df59fa7f4b "spi: orion: support armada extended baud

same maximum frequency. However, according the hardware datasheet, the
maximum frequency supported by the Armada 370 SoC is tclk/4, for the
Armada XP, Armada 38x and Armada 39x SoCs the limitation is 50MHz and
for the Armada 375 it is tclk/15.
This patch introduces new compatible strings to handle all these
case. In order to be future proof a compatible was created for each
SoC even if currently some SoCs seem using the same IP.

When the CONTINUE bit is set, the interrupt status we are polling to
identify if a transaction has finished can be sporadic. Even though
the transfer has finished, the interrupt status may erroneously
indicate that there is still data in the FIFO. This behaviour causes
random timeouts in large PIO transfers.
Instead of using the CONTINUE bit to control the CS lines, use the SPI
core's CS GPIO handling. Also, now that the CONTINUE bit is not being
used, we can poll for the ALLDONE interrupt to indicate transfer
completion.
