git://anongit.freedesktop.org/drm-intel into drm-next
Bunch of small fixupes all over. Plus a dma-buf patch that Sumit asked me
to cherry-pick since that's the only one he had in his tree.
There's a sparse issue outstanding in the color mgr stuff, but Lionel is
still working on something that actually appeases sparse.

Just a bit of wording polish plus mentioning that it can fail and must
be restarted.

Pull more power management and ACPI updates from Rafael Wysocki:
"The second batch of power management and ACPI updates for v4.6.
Included are fixups on top of the previous PM/ACPI pull request and
other material that didn't make into it but still should go into 4.6.
Among other things, there's a fix for an intel_pstate driver issue
uncovered by recent cpufreq changes, a workaround for a boot hang on
Skylake-H related to the handling of deep C-states by the platform and
a PCI/ACPI fix for the handling of IO port resources on non-x86
architectures plus some new device IDs and similar.
Specifics:
- Fix for an intel_pstate driver issue related to the handling of MSR
updates uncovered by the recent cpufreq rework (Rafael Wysocki).
- cpufreq core cleanups related to starting governors and frequency
synchronization during resume from system suspend and a locking fix
for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran).
- acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang,
Michael Neuling, Richard Cochran, Shilpasri Bhat).
- intel_idle driver update preventing some Skylake-H systems from
hanging during initialization by disabling deep C-states mishandled
by the platform in the problematic configurations (Len Brown).
- Intel Xeon Phi Processor x200 support for intel_idle
(Dasaratharaman Chandramouli).
- cpuidle menu governor updates to make it always honor PM QoS
latency constraints (and prevent C1 from being used as the fallback
C-state on x86 when they are set below its exit latency) and to
restore the previous behavior to fall back to C1 if the next timer
event is set far enough in the future that was changed in 4.4 which
led to an energy consumption regression (Rik van Riel, Rafael
Wysocki).
- New device ID for a future AMD UART controller in the ACPI driver
for AMD SoCs (Wang Hongcheng).
- Rockchip rk3399 support for the rockchip-io-domain adaptive voltage
scaling (AVS) driver (David Wu).
- ACPI PCI resources management fix for the handling of IO space
resources on architectures where the IO space is memory mapped
(IA64 and ARM64) broken by the introduction of common ACPI
resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi).
- Fix for the ACPI backend of the generic device properties API to
make it parse non-device (data node only) children of an ACPI
device correctly (Irina Tirdea).
- Fixes for the handling of global suspend flags (introduced in 4.4)
during hibernation and resume from it (Lukas Wunner).
- Support for obtaining configuration information from Device Trees
in the PM clocks framework (Jon Hunter).
- ACPI _DSM helper code and devfreq framework cleanups (Colin Ian
King, Geert Uytterhoeven)"

This adds the necessary data for handling io voltage domains on the rk3399.
As interesting tidbit, the rk3399 contains two separate iodomain areas.
One in the regular General Register Files (GRF) and one in PMUGRF in the
pmu power domain.

As the SAMA5D2 controller supports the 32-bit ECC strength, accept it
as a valid setting when required by the device tree or the NAND
parameter page.
Then configure the controller to use this new setting.

Starting with the SAMA5D2, there is a new revision of the Atmel PMECC
controller that can correct 32 bits in each sector. This controller is
not 100% compatible with the previous revision that corrected a maximum
of 24 bits by sector, as some register addresses overlap.
Using information from the device tree, we can configure the driver to
work with both versions.

The NFC controller used to accelerate the NAND transfers on SAMA5 chips
can use either RB_EDGE0 or RB_EDGE3 as its ready/busy interrupt bit.
Use the controller's compatible string to select the correct bit.

Pull more nfsd updates from Bruce Fields:
"Apologies for the previous request, which omitted the top 8 commits
from my for-next branch (including the SCSI layout commits). Thanks
to Trond for spotting my error!"
This actually includes the new layout types, so here's that part of
the pull message repeated:
"Support for a new pnfs layout type from Christoph Hellwig. The new
layout type is a variant of the block layout which uses SCSI features
to offer improved fencing and device identification.
Note this pull request also includes the client side of SCSI layout,
with Trond's permission"
* tag 'nfsd-4.6-1' of git://linux-nfs.org/~bfields/linux:
nfsd: use short read as well as i_size to set eof
nfsd: better layoutupdate bounds-checking
nfsd: block and scsi layout drivers need to depend on CONFIG_BLOCK
nfsd: add SCSI layout support
nfsd: move some blocklayout code

This is a simple extension to the block layout driver to use SCSI
persistent reservations for access control and fencing, as well as
SCSI VPD pages for device identification.
For this we need to pass the nfs4_client to the proc_getdeviceinfo method
to generate the reservation key, and add a new fence_client method
to allow for fence actions in the layout driver.

Pull more ARM DT changes from Arnd Bergmann:
"Here are some final updates for ARM SoC specific dts files:
- The i.MX changes were sent relatively late, and had a dependency on
the clk tree, so I delayed that a bit. Support for the new i.MX6qp
SoC and a couple of new boards is added in this branch.
- Uniphier renames a few files to match the final product names that
were decided by the company, kudos to the kernel developer(s) for
getting support upstream before the product release. Also two
boards are added. The patches were posted early enough and nice
overall, but we forgot to apply them and decided to give it some
more time in linux-next
- at91 has two small bug fixes"

Pull thermal updates from Zhang Rui:
- Fix a regression where bogus trip points on some Lenovo laptops start
to screw up thermal control after commit 81ad4276b505 ("Thermal:
initialize thermal zone device correctly").
On these Lenovo laptops, a bogus passive trip point is reported,
which is 0 degree Celsius. Without commit 81ad4276b505, thermal zone
fails to set cooling devices to proper cooling state, which is a bug.
But with commit 81ad4276b505 applied, the processors are always
throttled on these Lenovo laptops because the current temperature is
always higher than the passive trip point.
Fix things to ignore such bogus trip points. (Zhang Rui)
- Introduce Mediatek thermal driver. (Sascha Hauer)
- Introduce devm_ versions of OF thermal sensor register API. (Laxman
Dewangan)
- Changes in Kconfigs to allow compile test on UM arch. (Krzysztof
Kozlowski)
- Introduce Skylake support in intel_pch_thermal driver. (Srinivas
Pandruvada)
- Several small fixes on Rockchip, TI-SoC, Tegra, RCar, and Exynos
thermal drivers.

A mbigen hardware module can contain more than one device node. These device
nodes contain the same register definition.
mbigen_dev1:intc_dev1 {
...
reg = <0x0 0xc0080000 0x0 0x10000>;
...
};
mbigen_dev2:intc_dev2 {
...
reg = <0x0 0xc0080000 0x0 0x10000>;
...
};
In this case both devices try to request the same resource resulting in a
resource conflict.
To address this problem the devices need to be subnodes of the mbigen hardware
module, which then contains the unique register space.

The compiler store-fusion example in memory-barriers.txt uses a C
comment to represent arbitrary code that does not update a given
variable. Unfortunately, someone could reasonably interpret the
comment as instead referring to the following line of code. This
commit therefore replaces the comment with a string that more
clearly represents the arbitrary code.

The "transitivity" section mentions cumulativity in a potentially
confusing way. Contrary to the current wording, cumulativity is
not transitivity, but rather a hardware discipline that can be used
to implement transitivity on ARM and PowerPC CPUs. This commit
therefore deletes the mention of cumulativity.

The memory-barriers.txt discussion of local transitivity and
release-acquire chains leaves out discussion of the outcome of
the read from "u". This commit therefore adds an outcome showing
that you can get a "1" from this read even if the release-acquire
pairs don't line up.

The introduction of smp_load_acquire() and smp_store_release() had
the side effect of introducing a weaker notion of transitivity:
The transitivity of full smp_mb() barriers is global, but that
of smp_store_release()/smp_load_acquire() chains is local. This
commit therefore introduces the notion of local transitivity and
gives an example.

The current memory-barriers.txt does not address the possibility of
a write to a dereferenced pointer. This should be rare, but when it
happens, we need that write -not- to be clobbered by the initialization.
This commit therefore adds an example showing a data dependency ordering
a later data-dependent write.

The summary of the "CONTROL DEPENDENCIES" section incorrectly states that
barrier() may be used to prevent compiler reordering when more than one
leg of the control-dependent "if" statement start with identical stores.
This is incorrect at high optimization levels. This commit therefore
updates the summary to match the detailed description.
