85f94b5ef0 dt-bindings: mtd: document new "on-die" nand-ecc-mode
A number of NAND chips support a feature called on-die ECC, where the
NAND chip itself is capable of doing error detection and correction. The
new "on-die" value for nand-ecc-mode indicates that we want this
functionality to be used.

5be21d0a0f ARM: dts: rockchip: rename RK1108-evb to RV1108-evb
Rockchip finally named the SOC as RV1108, so change it
for compatible.

The rk1108/rv1108 is completely new to the market, so there no real
devices exist in the wild, only the Rockchip internal evaluation
board. Therefore we're not breaking any existing devices when
changing compatible values.

de120d092e dt-bindings: display: sun4i: Add component endpoint ID numbering scheme
The Allwinner display pipeline contains many hardware components, some
of which can consume data from one of multiple upstream components.
The numbering scheme of these components must be encoded into the device
tree so the driver can figure out which component out of two or more of
the same type it is supposed to use or program.

This patch adds the constraint that local endpoint IDs must be the index
or number of the remote endpoint's hardware block, for all components
in the display pipeline up to the TCONs.

Pull thermal management updates from Zhang Rui:

 - Fix a problem where orderly_shutdown() is called for multiple times
   due to multiple critical overheating events raised in a short period
   by platform thermal driver. (Keerthy)

 - Introduce a backup thermal shutdown mechanism, which invokes
   kernel_power_off()/emergency_restart() directly, after
   orderly_shutdown() being issued for certain amount of time(specified
   via Kconfig). This is useful in certain conditions that userspace may
   be unable to power off the system in a clean manner and leaves the
   system in a critical state, like in the middle of driver probing
   phase. (Keerthy)

 - Introduce a new interface in thermal devfreq_cooling code so that the
   driver can provide more precise data regarding actual power to the
   thermal governor every time the power budget is calculated. (Lukasz
   Luba)

 - Introduce BCM 2835 soc thermal driver and northstar thermal driver,
   within a new sub-folder. (Rafał Miłecki)

 - Introduce DA9062/61 thermal driver. (Steve Twiss)

 - Remove non-DT booting on TI-SoC driver. Also add support to fetching
   coefficients from DT. (Keerthy)

  Overall it seems normal though, a few small changes to the core,

  updates for new and existing hardware support.

  The biggest things are the TI clk driver rework to lay the groundwork

  Core:
   - clk_possible_parents debugfs file so we know which parents a clk

     instead of continuing

  New Drivers:

   - hi655x PMIC clks
   - AmLogic Meson SoC i2s and spdif audio clks and Mali graphics clks
   - Allwinner H5 SoCs and PRCM hardware

  Updates:
   - Nvidia Tegra T210 cleanups and non-critical fixes
   - TI OMAP cleanups in preparation for clkctrl support
   - trivial fixes like kcalloc(), devm_* conversions, and seq_puts()
   - ZTE zx296718 SoC VGA clks

  Here is my overall assessment of the subsystem:

   - There is clearly demand for this, both for the generic
     infrastructure and the specific OP-TEE implementation.

   - The code has gone through a large number of reviews, and the review
     comments have all been addressed, but the reviews were not coming
     up with serious issues any more and nobody volunteered to vouch for
     the quality.

   - The user space ioctl interface is sufficient to work with the
     OP-TEE driver, and it should in principle work with other TEE
     implementations that follow the GlobalPlatform[1] standards, but it
     might need to be extended in minor ways depending on specific
     requirements of future TEE implementations

   - The main downside of the API to me is how the user space is tied to
     the TEE implementation in hardware or firmware, but uses a generic
     way to communicate with it. This seems to be an inherent problem
     with what it is trying to do, and I could not come up with any
     better solution than what is implemented here.

2e4ab937ec Merge tag 'pm-extra-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management updates from Rafael Wysocki:
 "These add new CPU IDs to a couple of drivers, fix a possible NULL
  pointer dereference in the cpuidle core, update DT-related things in
  the generic power domains framework and finally update the
  suspend/resume infrastructure to improve the handling of wakeups from
  suspend-to-idle.

  Specifics:

   - Add Intel Gemini Lake CPU IDs to the intel_idle and intel_rapl
     drivers (David Box).

   - Add a NULL pointer check to the cpuidle core to prevent it from
     crashing on platforms with incomplete cpuidle configuration (Fei
     Li).

   - Fix DT-related documentation in the generic power domains (genpd)
     framework and add a MAINTAINERS entry for DT-related material in
     genpd (Viresh Kumar).

   - Update the system suspend/resume infrastructure to improve the
     handling of aborts of suspend transitions in progress in the wakeup
     framework and rework the suspend-to-idle core loop to make it
     possible to filter out spurious wakeup events (specifically the
     ones coming from ACPI) without resuming all the way up to user
     space every time (Rafael Wysocki)"

5a61ef74f2 powerpc/64s: Support new device tree binding for discovering CPU features
The ibm,powerpc-cpu-features device tree binding describes CPU features with
ASCII names and extensible compatibility, privilege, and enablement metadata
that allows improved flexibility and compatibility with new hardware.

The interface is described in detail in ibm,powerpc-cpu-features.txt in this
patch.

Currently this code is not enabled by default, and there are no released
firmwares that provide the binding.

b3f7787b46 drm/vc4: Add specific compatible strings for Cygnus.
Cygnus has V3D 2.6 instead of 2.1, and doesn't use the VC4 display
modules.  The V3D can be uniquely identified by the IDENT[01]
registers, and there's nothing to key off of for the display change
other than the lack of DT nodes for the display components, but it's
convention to have new compatible strings anyway.

b72a2816e3 drm/vc4: Turn the V3D clock on at runtime.
For the Raspberry Pi's bindings, the power domain also implicitly
turns on the clock and deasserts reset, but for the new Cygnus port we
start representing the clock in the devicetree.

v2: Document the clock-names property, check for -ENOENT for no clock
    in DT.
v3: Drop NULL checks around clk calls which embed NULL checks.
v4: Drop clk-names (feedback by Rob Herring)

400fd3a133 dt-bindings: iio: adc: add Meson8 and Meson8b support
The Amlogic Meson SAR ADC driver can be used on Meson8 and Meson8b
(probably on earlier SoC generations as well, but I don't have any
hardware available for testing that).
Add a separate compatible for Meson8 and Meson8b because it does not
need any of the BL30 magic (unlike the GX SoCs).

Pull staging/IIO updates from Greg KH:
 "Here is the big staging tree update for 4.12-rc1.

  It's a big one, adding about 350k new lines of crap^Wcode, mostly all
  in a big dump of media drivers from Intel. But there's other new
  drivers in here as well, yet-another-wifi driver, new IIO drivers, and
  a new crypto accelerator.

  We also deleted a bunch of stuff, mostly in patch cleanups, but also
  the Android ION code has shrunk a lot, and the Android low memory
  killer driver was finally deleted, much to the celebration of the -mm
  developers.

  All of these have been in linux-next with a few build issues that will
  show up when you merge to your tree"

drm/tegra: Changes for v4.12-rc1

This contains various fixes to the host1x driver as well as a plug for a
leak of kernel pointers to userspace.

A fairly big addition this time around is the Video Image Composer (VIC)
support that can be used to accelerate some 2D and image compositing
operations.

Furthermore the driver now supports FB modifiers, so we no longer rely
on a custom IOCTL to set those.

Finally this contains a few preparatory patches for Tegra186 support
which unfortunately didn't quite make it this time, but will hopefully
be ready for v4.13.

  Along with that, there's the usual huge number of changes for gadget
  drivers, xhci, and other stuff. Johan also finally refactored pretty
  much every driver that was looking at USB endpoints to do it in a
  common way, which will help prevent any "badly-formed" devices from

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.12 kernel cycle.

  Core changes:

   - Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
     This was a much discussed change. It affects use cases where people
     write drivers that might or might not be using GPIO resources. I
     have decided that this is the lesser evil right now.

   - Make gpiod_count() behave consistently across different hardware
     descriptions.

   - Fix the syntax around open drain/open source to not infer active
     high/low semantics.

  New drivers:

   - A new single-register fixed-direction framework driver for hardware
     that have lines controlled by a single register that just work in
     one direction (out or in), including IRQ support.

   - Support the Fintek F71889A GPIO SuperIO controller.

   - Support the National NI 169445 MMIO GPIO.

   - Support for the X-Gene derivative of the DWC GPIO controller

   - Support for the Rohm BD9571MWV-M PMIC GPIO controller.

   - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver
     and replace both the Gemini and the Moxa ART custom drivers with
     this driver.

  Driver improvements:

   - A whole slew of drivers have their spinlocks chaned to raw
     spinlocks as they provide irqchips, and thus we are progressing on
     realtime compliance.

   - Use devm_irq_alloc_descs() in a slew of drivers, getting managed
     resources.

   - Support for the embedded PWM controller inside the MVEBU driver.

   - Debounce, open source and open drain support for the Aspeed driver.

   - Misc smaller fixes like spelling and syntax and whatnot"
