This documents the binding used by Alexander Shiyan's DT support for
the clps711x SPI controller.
I've left the file name to match the ARM platform port name "clps711x"
for consistency with the other bindings, even though the compatible
string refers to the later ep7309 chip.
Linux no longer supports the old clps711x and ep72xx product lines,
but we still use the name. The entire family is now discontinued
by the manufacturer.

Another quiet release for SPI, almost entirely driver specific changes
with the diffstat dominated by two new drivers which are about two
thirds of it in terms of lines of code:
- New drivers for PIC32 standard and SQI controllers.
- The Cadence driver has had runtime PM support added and quite a few
fixes and cleanups.
- The flash-specific accelerated path support now has a feature query
interface.
- The pxa2xx driver has been moved to use the core DMA mapping support.

We continue ramping up platform support for 64-bit ARM machines,
with 111 individual non-merge changesets touching 21 platforms.
The LG1312 platform is completely new and is the first ARM
platform by LG that we support in the mainline kernel. Two other
SoCs got added that are updated versions of existing SoC
families, so the port mainly consists of new dts files:
- The Hisilicon Hip06/D03 is the latest server platform
from Huawei/Hisilicon, and follows the Hip05/D02 platform.
- Rockchip RK3399 follows the 32-bit RK3288 that is popular
in low-end Chromebooks and the 64-bit RK3368 that is mainly
found in chinese Android TV boxes.
The 96Boards HiKey based on the Hisilicon Hi6220 (Kirin 620)
gets a long-awaited overhaul with a lot of devices enabled in
the DT, so it should be much more usable with a mainline kernel
now. See also
https://plus.google.com/111524780435806926688/posts/PeGb2VsNhJd
A lot of work went into enabling new device drivers on existing
machines, but we also have a couple of new commercially
available machines:
- Google Pixel C laptop based on Tegra210
- Hardkernel Odroid C2 Based on Amlogic Meson GXBB (S905)
- Geekbuying GeekBox based on Rockchip RK3368
And finally, a couple of reference or development platforms
that are not end-user platforms but are used for trying out
the respective SoC platforms:
- Amlogic Meson GXBB P200 and P201 development systems
- NXP Layerscape 1043A QDS development board
- Hisilicon Hip06 D03 server board, as mentioned above
- LG1312 Reference Design

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.

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.

Pull ARM SoC DT updates from Kevin Hilman:
"As usual, quite a few device-tree updates in ARM land. There was one
minor churn in DTs due to relicensing under a dual-license, and lots
of little additions of new peripherals, features etc, but nothing
really exciting to call to your attention. Some higlights, focsuing
on support for new SoCs and boards:
- AT91: new boards: Overkiz, Acme Systems' Arietta G25
- tegra: HDA support
- bcm: new platforms: Buffalo WXR-1900DHP, SmartRG SR400ac, ASUS
RT-AC87U
- mvebu: new platforms: Compulab CM-A510, Armada 385-based Linksys
boards, DLink DNS-327L
- OMAP: new platforms: Baltos IR5221, LogicPD Torpedo, Toby-Churchill
SL50
- ARM: added support for Juno r1 board
- sunxi: A33 SoC support; new boards: A23 EVB, SinA33, GA10H-A33,
Mele A1000G
- imx: i.MX7D SoC support; new boards: Armadeus Systems APF6,
Gateworks GW5510, and aristainetos2 boards
