git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"Sort of on the quieter side this time, which is probably due more to
me not catching up as quickly on patch review than anything else.
Overall it seems normal though, a few small changes to the core,
mostly small non-critical fixes here and there as well as driver
updates for new and existing hardware support.
The biggest things are the TI clk driver rework to lay the groundwork
for clkctrl support in the next merge window and the AmLogic
audio/graphics clk support.
Core:
- clk_possible_parents debugfs file so we know which parents a clk
could possibly have
- Fix to make clk rate change notifiers stop on the first failure
instead of continuing
New Drivers:
- Mediatek MT6797 SoCs
- 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
- Rockchip clk-ids, fixups, and rename of rk1108 to rv1108
- IDT VersaClock 5P49V5935 support
- Renesas R-Car H3 and M3-W IMR clks and ES2.0 rev of R-Car H3
support"

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull TEE driver infrastructure and OP-TEE drivers from Arnd Bergmann:
"This introduces a generic TEE framework in the kernel, to handle
trusted environemtns (security coprocessor or software implementations
such as OP-TEE/TrustZone). I'm sending it separately from the other
arm-soc driver changes to give it a little more visibility, once the
subsystem is merged, we will likely keep this in the arm₋soc drivers
branch or have the maintainers submit pull requests directly,
depending on the patch volume.
I have reviewed earlier versions in the past, and have reviewed the
latest version in person during Linaro Connect BUD17.
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.

Initial patch for generic TEE subsystem.
This subsystem provides:
* Registration/un-registration of TEE drivers.
* Shared memory between normal world and secure world.
* Ioctl interface for interaction with user space.
* Sysfs implementation_id of TEE driver
A TEE (Trusted Execution Environment) driver is a driver that interfaces
with a trusted OS running in some secure environment, for example,
TrustZone on ARM cpus, or a separate secure co-processor etc.
The TEE subsystem can serve a TEE driver for a Global Platform compliant
TEE, but it's not limited to only Global Platform TEEs.
This patch builds on other similar implementations trying to solve
the same problem:
* "optee_linuxdriver" by among others
Jean-michel DELORME<jean-michel.delorme@st.com> and
Emmanuel MICHEL <emmanuel.michel@st.com>
* "Generic TrustZone Driver" by Javier González <javier@javigon.com>

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)"

i.MX drivers updates for 4.12:
- A series from Lucas Stach which partly rewrites the imx gpc driver
to support multiple power domains, and moves the related code from
imx platform into drivers folder.
- A series from Dong Aisheng which fixes the issues with Lucas' code
changes and improves things.
- Add workaround for i.MX6QP hardware erratum ERR009619 that is PRE
clocks may be stalled during the power up sequencing of the PU power
domain.
- Add imx-gpcv2 driver to support power domains managed by GPCv2 IP
block found on i.MX7 series of SoCs.

This is an almost complete re-write of the previous GPC power gating control
code found in the IMX architecture code. It supports both the old and the new
DT binding, allowing more domains to be added later and generally makes the
driver easier to extend, while keeping compatibility with existing DTBs.
As the result, all functionality regarding the power gating controller
gets removed from the IMX architecture GPC driver. It keeps only the
IRQ controller code in the architecture, as this is closely coupled to
the CPU idle implementation.

Introduce a ti_sci_pm_domains driver to act as a generic pm domain
provider to allow each device to attach and associate it's ti-sci-id so
that it can be controlled through the TI SCI protocol.
This driver implements a simple genpd where each device node has a
phandle to the power domain node and also must provide an index which
represents the ID to be passed with TI SCI representing the device using
a single phandle cell. The driver manually parses the phandle to get the
cell value. Through this interface the genpd dev_ops start and stop
hooks will use TI SCI to turn on and off each device as determined by
pm_runtime usage.

Add a generic power domain implementation, TI SCI PM Domains, that
will hook into the genpd framework and allow the TI SCI protocol to
control device power states.
Also, provide macros representing each device index as understood
by TI SCI to be used in the device node power-domain references.
These are identifiers for the K2G devices managed by the PMMC.

Secondly, Alex has unfortunately left the company and therefore won't

Pull "Broadcom maintainers changes for 4.12" from Florian Fainelli:
This pull request contains Broadcom ARM-based SoCs MAINTAINERS file updates for
4.12, please pull the following:
- Jon adds himself as a maintainer for the BCM5301X SoCs (Northstar) since he has
been contributing changes to these platforms for a while now
- Stephen Warren removes himself from the BCM2835 maintainers (Rasperrby Pi) since
in his own words he has not been active that much lately
- Eric adds Stefan Wahren as a maintainer for the BCM2835 platform since he has
been very active on it for neary 2 years now

I haven't been active in BCM2835 maintenance for quite a while; Eric's
been doing a great job. As such, remove myself from MAINTAINERS for that.

Microsemi's "Switchtec" line of PCI switch devices is already well
supported by the kernel with standard PCI switch drivers. However, the
Switchtec device advertises a special management endpoint with a separate
PCI function address and class code. This endpoint enables some additional
functionality which includes:
* Packet and Byte Counters
* Switch Firmware Upgrades
* Event and Error logs
* Querying port link status
* Custom user firmware commands
Add a switchtec kernel module which provides PCI driver that exposes a char
device. The char device provides userspace access to this interface
through read, write and (optionally) poll calls.
A userspace tool and library which utilizes this interface is available
at [1]. This tool takes inspiration (and borrows some code) from
nvme-cli [2]. The tool is largely complete at this time but additional
features may be added in the future.
