Another fairly quiet release, some new drivers with generic handling for
minor features but nothing that makes a substantial difference outside
of the subsystem or for most boards:
- Support for a bunch of new parameters which are present on enough
regulators to be worth having generic handling for in the framework.
- Fixes for some issues with printing constraints during boot which
should probably have gone in for v4.1 but didn't.
- New drivers for Dialog DA9062, Maxim MAX77621 and Qualcomm SPMI regulators.

No framework updates for the SPI API this time around aside from one
small fix, just driver improvments. Some highlights include:
- New driver support for CSR USP, Mikrotik RB4xx and Zynq GQSPI
controllers.
- Modernisation of the OMAP McSPI controller driver, moving it to
current APIs to enable support for a wider range of client drivers.
- DMA support for the bcm2835 controller.

Pull power management and ACPI updates from Rafael Wysocki:
"The rework of backlight interface selection API from Hans de Goede
stands out from the number of commits and the number of affected
places perspective. The cpufreq core fixes from Viresh Kumar are
quite significant too as far as the number of commits goes and because
they should reduce CPU online/offline overhead quite a bit in the
majority of cases.
From the new featues point of view, the ACPICA update (to upstream
revision 20150515) adding support for new ACPI 6 material to ACPICA is
the one that matters the most as some new significant features will be
based on it going forward. Also included is an update of the ACPI
device power management core to follow ACPI 6 (which in turn reflects
the Windows' device PM implementation), a PM core extension to support
wakeup interrupts in a more generic way and support for the ACPI _CCA
device configuration object.
The rest is mostly fixes and cleanups all over and some documentation
updates, including new DT bindings for Operating Performance Points.
There is one fix for a regression introduced in the 4.1 cycle, but it
adds quite a number of lines of code, it wasn't really ready before
Thursday and you were on vacation, so I refrained from pushing it on
the last minute for 4.1.

On some platforms (Like Qualcomm's SoCs), it is not decided until
runtime on what OPPs to use. The OPP tables can be fixed at compile
time, but which table to use is found out only after reading some efuses
(sort of an prom) and knowing characteristics of the SoC.
To support such platform we need to pass multiple OPP tables per device
and hardware should be able to choose one and only one table out of
those.
Update operating-points-v2 bindings to support that.

Current OPP (Operating performance point) device tree bindings have been
insufficient due to the inflexible nature of the original bindings. Over
time, we have realized that Operating Performance Point definitions and
usage is varied depending on the SoC and a "single size (just frequency,
voltage) fits all" model which the original bindings attempted and
failed.
The proposed next generation of the bindings addresses by providing a
expandable binding for OPPs and introduces the following common
shortcomings seen with the original bindings:
- Getting clock/voltage/current rails sharing information between CPUs.
Shared by all cores vs independent clock per core vs shared clock per
cluster.
- Support for specifying current levels along with voltages.
- Support for multiple regulators.
- Support for turbo modes.
- Other per OPP settings: transition latencies, disabled status, etc.?
- Expandability of OPPs in future.
This patch introduces new bindings "operating-points-v2" to get these problems
solved. Refer to the bindings for more details.
We now have multiple versions of OPP binding and only one of them should
be used per device.

The big thing this release has been Liam's addition of topology support
to the core. We've also seen quite a bit of driver work and the
continuation of Lars' refactoring for component support.
- Support for loading ASoC topology maps from firmware, intended to be
used to allow self-describing DSP firmware images to be built which
can map controls added by the DSP to userspace without the kernel
needing to know about individual DSP firmwares.
- Lots of refactoring to avoid direct access to snd_soc_codec where
it's not needed supporting future refactoring.
- Big refactoring and cleanup serieses for the Wolfson ADSP and TI
TAS2552 drivers.
- Support for TI TAS571x power amplifiers.
- Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs.
- Support for x86 systems with RT5650 and Qualcomm Storm.

This contains the EMC clock driver that's been exhaustively reviewed and
tested. It also includes a change to the clock core that allows a clock
provider to perform low-level reparenting of clocks. This is required by
the EMC clock driver because the reparenting needs to be done at a very
specific point in time during the EMC frequency switch.

Add DT bindings documentation for the new marvell-cesa driver.

We are about to add a new driver to support new features like using the
TDMA engine to offload the CPU.
Orion, Dove and Kirkwood platforms are already using the mv_cesa driver,
but Orion SoCs do not embed the TDMA engine, which means we will have to
differentiate them if we want to get TDMA support on Dove and Kirkwood.
In the other hand, the migration from the old driver to the new one is not
something all people are willing to do without first auditing the new
driver.
Hence we have to support the new compatible in the mv_cesa driver so that
new platforms with updated DTs can still attach their crypto engine device
to this driver.

The mv_cesa driver currently expects the SRAM memory region to be passed
as a platform device resource.
This approach implies two drawbacks:
- the DT representation is wrong
- the only one that can access the SRAM is the crypto engine
The last point is particularly annoying in some cases: for example on
armada 370, a small region of the crypto SRAM is used to implement the
cpuidle, which means you would not be able to enable both cpuidle and the
CESA driver.
To address that problem, we explicitly define the SRAM device in the DT
and then reference the sram node from the crypto engine node.
Also note that the old way of retrieving the SRAM memory region is still
supported, or in other words, backward compatibility is preserved.

Merge the mvebu/drivers branch of the arm-soc tree which contains
just a single patch bfa1ce5f38 ("bus:
mvebu-mbus: add mv_mbus_dram_info_nooverlap()") that happens to be
a prerequisite of the new marvell/cesa crypto driver.
Earlycon calculates UART clock as "BASE_BAUD * 16". In case of ARC
"BASE_BAUD" is calculated dynamically in runtime, basically it is an
alias to arc_early_base_baud(), which in turn just does
"arc_base_baud/16".
8250 UART on AXS/SDP board uses 33.3MHz clock source which is set in
"arc_base_baud" with this change.
Additional compatibility string "snps,arc-sdp" is introduced as well
because there're different flavours of AXS boards but they all share the
same motherboard and so it's possible to re-use the same code for
motherbord even if CPU daughterboard changes.

The rk3368 is the first ARM64 soc from Rockchip, but seems to share most
peripherals with the ARM32 soc, including the pinctrl functionality.
The only notable difference is - as with every Rockchip soc - that the
offsets in the General Register Files moved around and a split of the pmu
section of the rk3288 into pmu and pmugrf (pmu general register files)
sections. The pinctrl driver of course only needs the pmugrf registers
for controlling the pin settings.

- 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.
