Pull power management updates from Rafael Wysocki:
"These update the cpuidle poll state definition to reduce excessive
energy usage related to it, add new CPU ID to the RAPL power capping
driver, update the ACPI system suspend code to handle some special
cases better, extend the PM core's device links code slightly, add new
sysfs attribute for better suspend-to-idle diagnostics and easier
hibernation handling, update power management tools and clean up
cpufreq quite a bit.
Specifics:
- Modify the cpuidle poll state implementation to prevent CPUs from
staying in the loop in there for excessive times (Rafael Wysocki).
- Add Intel Cannon Lake chips support to the RAPL power capping
driver (Joe Konno).
- Add reference counting to the device links handling code in the PM
core (Lukas Wunner).
- Avoid reconfiguring GPEs on suspend-to-idle in the ACPI system
suspend code (Rafael Wysocki).
- Allow devices to be put into deeper low-power states via ACPI if
both _SxD and _SxW are missing (Daniel Drake).
- Reorganize the core ACPI suspend-to-idle wakeup code to avoid a
keyboard wakeup issue on Asus UX331UA (Chris Chiu).
- Prevent the PCMCIA library code from aborting suspend-to-idle due
to noirq suspend failures resulting from incorrect assumptions
(Rafael Wysocki).
- Add coupled cpuidle supprt to the Exynos3250 platform (Marek
Szyprowski).
- Add new sysfs file to make it easier to specify the image storage
location during hibernation (Mario Limonciello).
- Add sysfs files for collecting suspend-to-idle usage and time
statistics for CPU idle states (Rafael Wysocki).
- Update the pm-graph utilities (Todd Brandt).
- Reduce the kernel log noise related to reporting Low-power Idle
constraings by the ACPI system suspend code (Rafael Wysocki).
- Make it easier to distinguish dedicated wakeup IRQs in the
/proc/interrupts output (Tony Lindgren).
- Add the frequency table validation in cpufreq to the core and drop
it from a number of cpufreq drivers (Viresh Kumar).
- Drop "cooling-{min|max}-level" for CPU nodes from a couple of DT
bindings (Viresh Kumar).
- Clean up the CPU online error code path in the cpufreq core (Viresh
Kumar).
- Fix assorted issues in the SCPI, CPPC, mediatek and tegra186
cpufreq drivers (Arnd Bergmann, Chunyu Hu, George Cherian, Viresh
Kumar).
- Drop memory allocation error messages from a few places in cpufreq
and cpuildle drivers (Markus Elfring)"

Pul removal of obsolete architecture ports from Arnd Bergmann:
"This removes the entire architecture code for blackfin, cris, frv,
m32r, metag, mn10300, score, and tile, including the associated device
drivers.
I have been working with the (former) maintainers for each one to
ensure that my interpretation was right and the code is definitely
unused in mainline kernels. Many had fond memories of working on the
respective ports to start with and getting them included in upstream,
but also saw no point in keeping the port alive without any users.
In the end, it seems that while the eight architectures are extremely
different, they all suffered the same fate: There was one company in
charge of an SoC line, a CPU microarchitecture and a software
ecosystem, which was more costly than licensing newer off-the-shelf
CPU cores from a third party (typically ARM, MIPS, or RISC-V). It
seems that all the SoC product lines are still around, but have not
used the custom CPU architectures for several years at this point. In
contrast, CPU instruction sets that remain popular and have actively
maintained kernel ports tend to all be used across multiple licensees.
[ See the new nds32 port merged in the previous commit for the next
generation of "one company in charge of an SoC line, a CPU
microarchitecture and a software ecosystem" - Linus ]
The removal came out of a discussion that is now documented at
https://lwn.net/Articles/748074/. Unlike the original plans, I'm not
marking any ports as deprecated but remove them all at once after I
made sure that they are all unused. Some architectures (notably tile,
mn10300, and blackfin) are still being shipped in products with old
kernels, but those products will never be updated to newer kernel
releases.
After this series, we still have a few architectures without mainline
gcc support:
- unicore32 and hexagon both have very outdated gcc releases, but the
maintainers promised to work on providing something newer. At least
in case of hexagon, this will only be llvm, not gcc.
- openrisc, risc-v and nds32 are still in the process of finishing
their support or getting it added to mainline gcc in the first
place. They all have patched gcc-7.3 ports that work to some
degree, but complete upstream support won't happen before gcc-8.1.
Csky posted their first kernel patch set last week, their situation
will be similar
[ Palmer Dabbelt points out that RISC-V support is in mainline gcc
since gcc-7, although gcc-7.3.0 is the recommended minimum - Linus ]"

The display pipeline on the A80 SoC has what is called the Detail
Enhancement Unit, or DEU for short, block in between the display
frontend and backend. This unit can sharpen images in both luma
and chroma channels. It seems to also do colorspace conversion.
This patch adds the device tree binding for this hardware block.

Link: https://patchwork.freedesktop.org/patch/msgid/20180315114136.24747-3-wens@csie.org
The A80 has 2 or 3 TCONs. The documentation and vendor kernel are very
vague about the third TCON, to the point that it might not exist.
In the documentation, the first TCON is missing channel 1, and the
second is missing channel 0. However the vendor kernel seems to be
able to use them regardless. Here we model them like the old TCONs.
An oddity is that TCON0 requires the reset control for the eDP block
to be deasserted, for any register access to stick.
This patch adds compatible strings for TCON0 and TCON1, with TCON0
requiring an extra "edp" reset control.

Pull dmaengine fixes from Vinod Koul:
"Two small fixes are for this cycle:
- fix max_chunk_size for rcar-dmac for R-Car Gen3
- fix clock resource of mv_xor_v2"
* tag 'dmaengine-fix-4.16-rc5' of git://git.infradead.org/users/vkoul/slave-dma:
dmaengine: mv_xor_v2: Fix clock resource by adding a register clock
dmaengine: rcar-dmac: fix max_chunk_size for R-Car Gen3
On the CP110 components which are present on the Armada 7K/8K SoC we need
to explicitly enable the clock for the registers. However it is not
needed for the AP8xx component, that's why this clock is optional.
With this patch both clock have now a name, but in order to be backward
compatible, the name of the first clock is not used. It allows to still
use this clock with a device tree using the old binding.

Remove metag architecture
These patches remove the metag architecture and tightly dependent
drivers from the kernel. With the 4.16 kernel the ancient gcc 4.2.4
based metag toolchain we have been using is hitting compiler bugs, so
now seems a good time to drop it altogether.

- DT overlay applying rework (Frank Rowand)
Move duplicating and unflattening of an overlay flattened devicetree
(FDT) into the overlay application code. To accomplish this,
of_overlay_apply() is replaced by of_overlay_fdt_apply().
The Stream Buffer for EtherAVB-IF (STBE) is an optional component, and
is not present on all SoCs.
Document this in the DT bindings, including a list of SoCs that do have
it.
