for the TI Davinci family of SoCs. So far those clks have been supported
with a custom implementation of the clk API in the arch port instead of in
the CCF. With this driver merged we're one step closer to having a single
clk API implementation.
The other large diff is from the Amlogic clk driver that underwent some
major surgery to use regmap. Beyond that, the biggest hitter is Samsung
which needed some reworks to properly handle clk provider power domains
and a bunch of PLL rate updates.
The core framework was fairly quiet this round, just getting some cleanups
and small fixes for some of the more esoteric features. And the usual
set of driver non-critical fixes, cleanups, and minor additions are here as
well.
Core:
- Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
- debugfs ops macroized to shave some lines of boilerplate code
- Always calculate the phase instead of caching it in clk_get_phase()
- More __must_check on bulk clk APIs

* A rework of the filesytem-dax implementation provides for detection of
unmap operations (truncate / hole punch) colliding with in-progress
device-DMA. A fix for these collisions remains a work-in-progress
pending resolution of truncate latency and starvation regressions.
* The of_pmem driver expands the users of libnvdimm outside of x86 and
ACPI to describe an implementation of persistent memory on PowerPC with
Open Firmware / Device tree.
* Address Range Scrub (ARS) handling is completely rewritten to account for
the fact that ARS may run for 100s of seconds and there is no platform
defined way to cancel it. ARS will now no longer block namespace
initialization.
* The NVDIMM Namespace Label implementation is updated to handle label
areas as small as 1K, down from 128K.
* Miscellaneous cleanups and updates to unit test infrastructure.

Merge tag 'libnvdimm-for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"This cycle was was not something I ever want to repeat as there were
several late changes that have only now just settled.
Half of the branch up to commit d2c997c0f1 ("fs, dax: use
page->mapping to warn...") have been in -next for several releases.
The of_pmem driver and the address range scrub rework were late
arrivals, and the dax work was scaled back at the last moment.
The of_pmem driver missed a previous merge window due to an oversight.
A sense of obligation to rectify that miss is why it is included for
4.17. It has acks from PowerPC folks. Stephen reported a build failure
that only occurs when merging it with your latest tree, for now I have
fixed that up by disabling modular builds of of_pmem. A test merge
with your tree has received a build success report from the 0day robot
over 156 configs.
An initial version of the ARS rework was submitted before the merge
window. It is self contained to libnvdimm, a net code reduction, and
passing all unit tests.
The filesystem-dax changes are based on the wait_var_event()
functionality from tip/sched/core. However, late review feedback
showed that those changes regressed truncate performance to a large
degree. The branch was rewound to drop the truncate behavior change
and now only includes preparation patches and cleanups (with full acks
and reviews). The finalization of this dax-dma-vs-trnucate work will
need to wait for 4.18.
Summary:
- A rework of the filesytem-dax implementation provides for detection
of unmap operations (truncate / hole punch) colliding with
in-progress device-DMA. A fix for these collisions remains a
work-in-progress pending resolution of truncate latency and
starvation regressions.
- The of_pmem driver expands the users of libnvdimm outside of x86
and ACPI to describe an implementation of persistent memory on
PowerPC with Open Firmware / Device tree.
- Address Range Scrub (ARS) handling is completely rewritten to
account for the fact that ARS may run for 100s of seconds and there
is no platform defined way to cancel it. ARS will now no longer
block namespace initialization.
- The NVDIMM Namespace Label implementation is updated to handle
label areas as small as 1K, down from 128K.
- Miscellaneous cleanups and updates to unit test infrastructure"

This reverts commit f0f56716fc.
According to Thierry's view,
https://www.spinics.net/lists/linux-ide/msg55357.html
some hardware-specific drivers already use their own resets,
and the common reset might make a path to occur double controls of resets.
For now, revert the commit that adds reset control support to ahci-platform,
and hold until the solution is confirmed not be affect all hardware-specific
drivers.

This introduces a simpler and generic method for for finding (and mapping)
the TBIPA register.
Instead of relying of complicated logic for finding the TBIPA register
address based on the MDIO or MII register block base
address, which even in some cases relies on undocumented shadow registers,
a second "reg" entry for the mdio bus devicetree node specifies the TBIPA
register.
Backwards compatibility is kept, as the existing logic is applied when
only a single "reg" mapping is specified.

Pull i2c updates from Wolfram Sang:
-I2C core now reports proper OF style module alias. I'd like to repeat
the note from the commit msg here (Thanks, Javier!):
NOTE: This patch may break out-of-tree drivers that were relying
on this behavior, and only had an I2C device ID table even
when the device was registered via OF.
There are no remaining drivers in mainline that do this, but
out-of-tree drivers have to be fixed and define a proper OF
device ID table to have module auto-loading working.
- new driver for the SynQuacer I2C controller
- major refactoring of the QUP driver
- the piix4 driver now uses request_muxed_region which should fix a
long standing resource conflict with the sp5100_tco watchdog

The main addition this time around is the new ARM "SCMI" framework,
which is the latest in a series of standards coming from ARM to do power
management in a platform independent way. This has been through many
review cycles, and it relies on a rather interesting way of using the
mailbox subsystem, but in the end I agreed that Sudeep's version was
the best we could do after all.
Other changes include:
- the ARM CCN driver is moved out of drivers/bus into drivers/perf,
which makes more sense. Similarly, the performance monitoring
portion of the CCI driver are moved the same way and cleaned up
a little more.
- a series of updates to the SCPI framework
- support for the Mediatek mt7623a SoC in drivers/soc
- support for additional NVIDIA Tegra hardware in drivers/soc
- a new reset driver for Socionext Uniphier
- lesser bug fixes in drivers/soc, drivers/tee, drivers/memory, and
drivers/firmware and drivers/reset across platforms

This release brings up a new platform based on the old ARM9 core: the
Nuvoton NPCM is used as a baseboard management controller, competing
with the better known ASpeed AST2xx series.
Another important change is the addition of ARMv7-A based chips
in mach-stm32. The older parts in this platform are ARMv7-M based
microcontrollers, now they are expanding to general-purpose workloads.
The other changes are the usual defconfig updates to enable additional
drivers, lesser bugfixes. The largest updates as often are the ongoing
OMAP cleanups, but we also have a number of changes for the older
PXA and davinci platforms this time.
For the Renesas shmobile/r-car platform, some new infrastructure
is needed to make the watchdog work correctly.
Supporting Multiprocessing on Allwinner A80 required a significant
amount of new code, but is not doing anything unexpected.

This is the usual set of changes for device trees, with over 700
non-merged changesets. There is an ongoing set of dtc warning fixes and
the usual bugfixes, cleanups and added device support.
The most interesting bit as usual is support for new machines listed
below:
- The Allwinner H6 makes its debut with the Pine-H64 board, and we get
two new machines based on its older siblings: the H5 based OrangePi
Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side,
we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2
Zero development board (based on H2).
- NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972
development board and p2888 CPU module.
- The Nuvoton npcm750 is a BMC that was newly added, for now we only
support running on the evaluation board.
- STmicroelectronics stm32 gains support for the stm32mp157c and two
evaluation boards.
- The Toradex Colibri board family grows a few members based on the
i.MX6ULL variant.
- The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6
family of chips.
- The Phytec phyBOARD Mira is a family of industrial boards based on
i.MX6. For now, four models get added.
- TI am335x based PDU-001 is an industrial embedded machine used for
traffic monitoring
- The Aspeed platform now supports running on the BMC on the Qualcomm
Centriq 2400 server
- Samsung Exynos4 based Galaxy S3 is a family of mobile phones Qualcomm
msm8974 based Galaxy S5 is a rather different phone made by the same
company.
- The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file
for the various boards made by Xilinx themselves, as well as the
Digilent Zybo Z7.
- The ARM Versatile family now supports the "IB2" interface board.
- The Renesas H2 based "Stout" and the H3 based Salvator-X are more
evaluation boards named after a kind of beer, as most of them are.
The r8a77980 (V3H) based "Condor" apparently doesn't follow that

- Build dtc lexer and parser files instead of using shipped versions.
- Rework overlay apply API to take an FDT as input and apply overlays
in a single step.
- Add a phandle lookup cache. This improves boot time by hundreds of
msec on systems with large DT.
- Add trivial mcp4017/18/19 potentiometers bindings.
- Remove VLA stack usage in DT code.

This is mostly updates of the usual drivers: arcmsr, qla2xx, lpfc,
ufs, mpt3sas, hisi_sas. In addition we have removed several really
old drivers: sym53c416, NCR53c406a, fdomain, fdomain_cs and removed
the old scsi_module.c initialization from all remaining drivers. Plus
an assortment of bug fixes, initialization errors and other minor
fixes.

This became a large update. The changes are scattered widely,
and majority of them are attributed to ASoC componentization.
The gitk output made me dizzy, but it's slightly better than
London tube.
OK, below are some highlights:
- Continued hardening works in ALSA PCM core; most of the
existing syzkaller reports should have been covered.
- USB-audio got the initial USB Audio Class 3 support, as well
as UAC2 jack detection support and more DSD-device support.
- ASoC componentization: finally each individual driver was
converted to components framework, which is more future-proof
for further works. Most of conversations were systematic.
- Lots of fixes for Intel Baytrail / Cherrytrail devices with
Realtek codecs, typically tablets and small PCs.
- Fixes / cleanups for Samsung Odroid systems
- Cleanups in Freescale SSI driver
- New ASoC drivers:
* AKM AK4458 and AK5558 codecs
* A few AMD based machine drivers
* Intel Kabylake machine drivers
* Maxim MAX9759 codec
* Motorola CPCAP codec
* Socionext Uniphier SoCs

New drivers:
- Nintendo Wii GameCube GPIO, known as "Hollywood"
- Raspberry Pi mailbox service GPIO expander
- Spreadtrum main SC9860 SoC and IEC GPIO controllers.
Improvements:
- Implemented .get_multiple() callback for most of the
high-performance industrial GPIO cards for the ISA bus.
- ISA GPIO drivers now select the ISA_BUS_API instead of
depending on it. This is merged with the same pattern
for all the ISA drivers and some other Kconfig cleanups
related to this.
Cleanup:
- Delete the TZ1090 GPIO drivers following the deletion of
this SoC from the ARM tree.
- Move the documentation over to driver-api to conform with
the rest of the kernel documentation build.
- Continue to make the GPIO drivers include only
<linux/gpio/driver.h> and not the too broad <linux/gpio.h>
that we want to get rid of.
- Managed to remove VLA allocation from two drivers pending
more fixes in this area for the next merge window.
- Misc janitorial fixes.

Here is the big set of Staging/IIO driver patches for 4.17-rc1.
It is a lot, over 500 changes, but not huge by previous kernel release
standards. We deleted more lines than we added again (27k added vs. 91k
remvoed), thanks to finally being able to delete the IRDA drivers and
networking code.
We also deleted the ccree crypto driver, but that's coming back in
through the crypto tree to you, in a much cleaned-up form.
Added this round is at lot of "mt7621" device support, which is for an
embedded device that Neil Brown cares about, and of course a handful of
new IIO drivers as well.
And finally, the fsl-mc core code moved out of the staging tree to the
"real" part of the kernel, which is nice to see happen as well.
Full details are in the shortlog, which has all of the tiny cleanup
patches described.

Pull USB/PHY updates from Greg KH:
"Here is the big set of USB and PHY driver patches for 4.17-rc1.
Lots of USB typeC work happened this round, with code moving from the
staging directory into the "real" part of the kernel, as well as new
infrastructure being added to be able to handle the different types of
"roles" that typeC requires.
There is also the normal huge set of USB gadget controller and driver
updates, along with XHCI changes, and a raft of other tiny fixes all
over the USB tree. And the PHY driver updates are merged in here as
well as they interacted with the USB drivers in some places.
All of these have been in linux-next for a while with no reported
issues"

The low-pin-count (LPC) interface of Hip06/Hip07 accesses I/O port space of
peripherals.
Implement the LPC host controller driver which performs the I/O operations
on the underlying hardware. We don't want to touch existing drivers such
as ipmi-bt, so this driver applies the indirect-IO introduced in the
previous patch after registering an indirect-IO node to the indirect-IO
devices list which will be searched by the I/O accessors to retrieve the
host-local I/O port.
The driver config is set as a bool instead of a tristate. The reason here
is that, by the very nature of the driver providing a logical PIO range, it
does not make sense to have this driver as a loadable module. Another more
specific reason is that the Huawei D03 board which includes Hip06 SoC
requires the LPC bus for UART console, so should be built in.

This does add an IPMI BMC server-side driver, to allow a Linux
system to act as an IPMI controller. That's the biggest change,
but it is just a new driver that is fairly narrow in use.
The other largish change is removing ACPI SPMI probe support,
which should have never really been there in the beginning.

Pull IPMI updates from Corey Minyard:
"Mostly small changes, as usual.
This does add an IPMI BMC server-side driver, to allow a Linux system
to act as an IPMI controller. That's the biggest change, but it is
just a new driver that is fairly narrow in use.
The other largish change is removing ACPI SPMI probe support, which
should have never really been there in the beginning"

A quiet release for SPI, some fixes and small updates for individual
drivers with one bigger change from Linus Walleij which coverts the
bitbanging SPI driver to use the GPIO descriptor API from Linus Walleij.
Since GPIO descriptors were used by platform data this means there's a
few changes in arch/ making relevant updates for a few platforms and one
misc driver that are affected.

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.
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.

The Meson8m2 SoC uses a similar (potentially even identical) register
layout for the dwmac glue as Meson8b and GXBB. Unfortunately there is no
documentation available.
Testing shows that both, RMII and RGMII PHYs are working if they are
configured as on Meson8b. Add a new compatible string to the
documentation so differences (if there are any) between Meson8m2 and the
other SoCs can be taken care of within the driver.

It's common practice to store MAC addresses for network interfaces into
nvmem devices. However the code to actually do this in the kernel lacks,
so this patch adds of_get_nvmem_mac_address() for drivers to obtain the
address from an nvmem cell provider.
This is particulary useful on devices where the ethernet interface cannot
be configured by the bootloader, for example because it's in an FPGA.

minor additions like pins for 2ch i2s0 and the cif test clocks as well
as a default rate for ACLK_VIO that should be 400MHz according to the TRM.
The rk3328 got uart dmas fixed - a non-critical fix, as nobody was using
that so far.
New boards are the rk3328-based roc-rk3328-cc, the rk3368-based Lion-SOM
+ baseborad from Theobroma Systems and a standalone variant of the Sapphire
board, as a lot of people where using that without the Exkavator baseboard.
Sapphire also saw a lot of small cleanups of things that are not part
of the actual Sapphire board, but the baseboard instead. The rk3399-puma
board got i2s and tsadc support and Gru got its DP node enabled.

Pull "Rockchip dts64 changes for 4.17" from Heiko Stübner:
The rk3399 gained support its Cadence displayport controller and some
minor additions like pins for 2ch i2s0 and the cif test clocks as well
as a default rate for ACLK_VIO that should be 400MHz according to the TRM.
The rk3328 got uart dmas fixed - a non-critical fix, as nobody was using
that so far.
New boards are the rk3328-based roc-rk3328-cc, the rk3368-based Lion-SOM
+ baseborad from Theobroma Systems and a standalone variant of the Sapphire
board, as a lot of people where using that without the Exkavator baseboard.
Sapphire also saw a lot of small cleanups of things that are not part
of the actual Sapphire board, but the baseboard instead. The rk3399-puma
board got i2s and tsadc support and Gru got its DP node enabled.

01d675f159 ARM: shmobile: rcar-gen2: Add watchdog support
58adf1ba0d ARM: shmobile: Add watchdog support
* SoC
- Identify R-Car V3H (r8a77980) and M3N (r8a77965)
- Enable R-Car Gen2 regulator quirk for Stout board with H3 (r8a7790) SoC
Marek Vaust says "Regulator setup is suboptimal on H2 Stout too. The
Stout newly has two DA9210 regulators, so the quirk is extended to
handle another DA9210 at i2c address 0x70."
- Add watchdog support
This is the SoC portion of the following solution. It is not yet
enabled in DT as it is not functional without clock dependencies
in place.
Fabrizio Castro says "this series has been around for some time as RFC,
and it has collected useful comments from the community along the way.
The solution proposed by this patch set works for most R-Car Gen2 and
RZ/G1 devices, but not all of them. We now know that for some R-Car
Gen2 early revisions there is no proper software fix. Anyway, no
product has been built around early revisions, but development boards
mounting early revisions (basically prototypes) are still out there.
As a result, this series isn't enabling the internal watchdog on R-Car
Gen2 boards, developers may enable it in board specific device trees if
needed. This series has been tested by me on the iwg20d, iwg22d,
Lager, Alt, and Koelsch boards.
The problem
===========
To deal with SMP on R-Car Gen2 and RZ/G1, we install a reset vector to
ICRAM1 and we program the [S]BAR registers so that when we turn ON the
non-boot CPUs they are redirected to the reset vector installed by Linux
in ICRAM1, and eventually they continue the execution to RAM, where the
SMP bring-up code will take care of the rest. The content of the [S]BAR
registers survives a watchdog triggered reset, and as such after the
watchdog fires the boot core will try and execute the SMP bring-up code
instead of jumping to the bootrom code.
The fix
=======
The main strategy for the solution is to let the reset vector decide if
it needs to jump to shmobile_boot_fn or to the bootrom code. In a
watchdog triggered reset scenario, since the [S]BAR registers keep their
values, the boot CPU will jump into the newly designed reset vector, the
assembly routine will eventually test WOVF (a bit in register RWTCSRA
that indicates if the watchdog counter has overflown, the value of this
bit gets retained in this scenario), and jump to the bootrom code which
will in turn load up the bootloader, etc. When bringing up SMP or using
CPU hotplug, the reset vector will jump to shmobile_boot_fn instead."
* R-Car Rst
- Add support for R-Car V3H (r8a77980) and V3H (r8a77980)
* R-Car SYSC
- Mark rcar_sysc_matches[] __initconst
Geert Uytterhoeven says "This frees another 1764 bytes
(arm32/shmobile_defconfig) or 1000 bytes (arm64/renesas_defconfig) of
memory after kernel init."
- Fix power area parents
Sergei Shtylyov says "According to the figure 9.2(b) of the R-Car
Series, 3rd Generation User’s Manual: Hardware Rev. 0.80 the A2IRn and
A2SCn power areas in R8A77970 have the A3IR area as a parent, thus the
SYSC driver has those parents wrong.."

Here is our bunch of changes for mach-sunxi for this release cycle. This is
basically only about bringing the SMP support to the A80, which has a bug
in hardware and cannot use PSCI like the other SoCs we have.

ARM: sunxi: mc-smp: Split out SoC-specific device node lookup sequence
ARM: sunxi: mc-smp: Use DT enable-method for sun9i A80 SMP
ARM: sunxi: mc-smp: Fix "lookback" typo
ARM: sun9i: smp: Support cpu0 hotplug
dt-bindings: ARM: sunxi: Document A80 SoC secure SRAM usage by SMP hotplug
ARM: sun9i: smp: Support CPU/cluster power down and hotplugging for cpu1~7
ARM: sun9i: Support SMP bring-up on A80
Some qcom platforms make some GPIOs or pins unavailable for use
by non-secure operating systems, and thus reading or writing the
registers for those pins will cause access control issues.
Introduce a DT property to describe the set of GPIOs that are
available for use so that higher level OSes are able to know what
pins to avoid reading/writing.

The Pyra-Handheld originally used the tca6424 but recently we have
replaced it by the pin and package compatible pcal6524. So let's
add this to the bindings and the driver.
And while we are at it, the pcal9555a does not have a compatible entry
either but is already supported by the device id table.

The Allwinner H6 SoC has two pin controllers, one main controller
(called CPUX-PORT in user manual) and one controller in CPUs power
domain (called CPUS-PORT in user manual).
This commit introduces support for the main pin controller on H6.
The pin bank A and B are not wired out and hidden from the SoC's
documents, however it's shown that the "ATE" (an AC200 chip
co-packaged with the H6 die) is connected to the main SoC die via these
pin banks. The information about these banks is just copied from the BSP
pinctrl driver, but re-formatted to fit the mainline pinctrl driver
format. The GPIO functions are dropped, as they're impossible to use --
except a GPIO&IRQ only pin (PB20) which might be the IRQ of ATE.

Use the "reg" property to specify the processor's local APIC ID instead of
setting it to the CPU node index in Device Tree.
Local APIC ID is assigned by hardware and visible in the APIC ID register.
Some processor models allow APIC ID to be changed by software, but CPUID
instruction executed with %eax = 0x0b always returns the initial ID in %edx.
Local APIC ID does not match the node index in many systems.

clock is optional because not all the SoCs using this IP need it but at
least for Armada 7K/8K it is actually mandatory.
The binding documentation is updated accordingly.

Fun set of conflict resolutions here...
For the mac80211 stuff, these were fortunately just parallel
adds. Trivially resolved.
In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.
In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.
The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.
The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:
====================
Due to bug fixes found by the syzkaller bot and taken into the for-rc
branch after development for the 4.17 merge window had already started
being taken into the for-next branch, there were fairly non-trivial
merge issues that would need to be resolved between the for-rc branch
and the for-next branch. This merge resolves those conflicts and
provides a unified base upon which ongoing development for 4.17 can
be based.
Conflicts:
drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f95
(IB/mlx5: Fix cleanup order on unload) added to for-rc and
commit b5ca15ad7e (IB/mlx5: Add proper representors support)
add as part of the devel cycle both needed to modify the
init/de-init functions used by mlx5. To support the new
representors, the new functions added by the cleanup patch
needed to be made non-static, and the init/de-init list
added by the representors patch needed to be modified to
match the init/de-init list changes made by the cleanup
patch.
Updates:
drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
prototypes added by representors patch to reflect new function
names as changed by cleanup patch
drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
stage list to match new order from cleanup patch

Quite a lot happened in this cycle, with a total of 95 non-merge
commits. The most interesting parts are listed below:
Synopsys has been adding better support for USB 3.1 to dwc3. The same
series also sets g_mass_storage's max speed to SSP.
Roger Quadros (TI) added support for dual-role using the OTG block
available in some dwc3 implementations, this makes sure that AM437x
can swap roles in runtime.
We have a new SoC supported in dwc3 now - Amlogic Meson GX - thanks to
the work of Martin Blumenstingl.
We also have a ton of changes in dwc2 (51% of all changes, in
fact). The most interesting part there is the support for
Hibernation (a Synopsys PM feature).
Apart from these, we have our regular set of non-critical fixes all
over the place.

Detailed description for this pull request:
1. Add exported extcon function in order to support OF graph binding
- The extcon consumer driver used the "extcon = <&extcon's phandle"
property in device-tree in order to bind between extcon provider
and consumer driver. But, OF graph method is better than 'extcon' property.
So, extcon subsystem adds the following function to support OF graph binding.
: extcon_find_edev_by_node(struct device_node *node)
- Create the immutable branch ("ib-extcon-drm-dt-v4.17") for both drm-misc
and device-tree subsystem. This immutable branch contains the use-case of
OF graph binding for EXTCON_HDMI connector between MHL device driver
and extcon provider driver.
2. Fix minor issues of extcon device drivers
- Remove platform_data and covert to fully use GPIO descriptor for extcon-gpio.c
- Remove workaround code for id pin direction from extcon-inte-int3496.c
because GPIO ACPI library does support it with generic way.
- Set direction and drv flags for V5 boost GPIO because of fixing
the firmware bug.

This adds a new binding for the Power Sleep Controller (PSC) for the
mach-davinci family of processors.
Note: Although TI Keystone has a very similar PSC, we are not using the
existing bindings. Keystone is using a legacy one-node-per-clock binding
(actually two nodes if you count the separate reset binding for the same
IP block). Also, some davinci LPSCs have quirks that aren't handled by
the keystone bindings, so we would be adding one compatible string per
clock with quirks instead of just a new compatible string for each
controller.

This adds a new binding for the PLL IP blocks in the mach-davinci

but these bindings can also work for other SoCs in this family just
by adding new compatible strings.
Note: Although these PLL controllers are very similar to the TI Keystone
SoCs, we are not re-using those bindings. The Keystone bindings use a
legacy one-node-per-clock binding. Furthermore, the mach-davinici SoCs
have a slightly different PLL register layout and a number of quirks
that can't be handled by the existing bindings, so the keystone bindings
could not be used as-is anyway.

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.

Freescale i.MX21 and i.MX31 SoCs contain a Random Number Generator
Accelerator module (RNGA), which is replaced by RNGB and RNGC modules
on later i.MX SoC series, the change adds a new compatible property
to describe the controller.
Since all versions of Freescale RNG modules are legacy, apparently
the documentation file has no more potential for further extensions,
nevertheless generalize it by removing explicit RNGC specifics.

The extcon property is used to detect the cable-state but some boards
just connect the type-c phy to a regular USB-A connector without any
power-delivery and thus no controller reporting the cable-state.
So the extcon property is not really a required property, move it to be
optional instead.

Let's add support for the GPIO controlled USB PHY on the MDM6600 modem.
It is used on some Motorola Mapphone series of phones and tablets such
as Droid 4.
The MDM6600 is hardwired to the first OHCI port in the Droid 4 case, and
is controlled by several GPIOs. The USB PHY is integrated into the MDM6600
device it seems. We know this as we get L3 errors from omap-usb-host if
trying to use the PHY before MDM6600 is configured.
The GPIOs controlling MDM6600 are used to power device on and off, to
configure the USB start-up mode (normal mode versus USB flashing), and
they also tell the state of the MDM6600 device.
The two start-up mode GPIOs are dual-purposed and used for out of band
(OOB) wake-up for USB and TS 27.010 serial mux. But we need to configure
the USB start-up mode first to get MDM6600 booted in the right mode to
be usable in the first place.
Note that the Motorola Mapphone Linux kernel tree has a "radio-ctrl"
driver for modems. But it really does not control the radio at all, it
just controls the modem power and start-up mode for USB. So I came to
the conclusion that we're better off having this done in the USB PHY
driver. For adding support for USB flashing mode, we can later on add
a kernel module option for flash_mode=1 or something similar.
Also note that currently there is no PM runtime support for the OHCI
on omap variant SoCs. So for low(er) power idle states, currenty both
ohci-platform and phy-mapphone-mdm6600 must be unloaded or unbound.
For reference here is what I measured for total power consumption on
an idle Droid 4 with and without USB related MDM6600 modules:
idle lcd off phy-mapphone-mdm6600 ohci-platform
153mW 284mW 344mW
So it seems that MDM6600 is currently not yet idling even with it's
radio turned off, but that's something that is beyond the control of
this USB PHY driver. This patch does get us to the point where modem
data and GPS are usable with libqmi and ModemManager for example.
Voice calls need more audio driver work.

example with a USB flash drive) may time out (most often seen on boards
with mainline u-boot, where the bootloader does not initialize the USB3

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.

Instead of having an early init function check the machine compatible
and installing multi-cluster SMP support for the A80 if it matches,
use a new cpu enable-method string. This makes the platform support
future proof in case anyone manages to add PSCI support.
The original init code for the SMP support is changed into the
.prepare_cpus callback in the smp_operations structure. Instead of
panicing when resources are missing like on some platforms, our code
merely guards against engaging SMP or CPU hotplug and returns an error.

There is a need to use DA7219 as DAI clock master for other codecs
within a system, which means that the DAI clocks are required to
remain, regardless of whether the codec is actually running
playback/capture. To be able to expose control of the DAI clocking
the common clock framework has been employed.
The current implementation adds a simple clock gate for enabling
and disabling the DAI clocks, with no rate control supported
(this is still handled through standard hw_params() functions as
before). If DT is enabled then the clock is added to the OF
providers list, otherwise a clkdev lookup is used.

registers partitioned in a funky manner that requires the clock
control setup to be latched for PRCM to be notified of the change. This
is accomplished with a separate control bit under the register. Add
support for this clock latching support to divider and mux clocks.

The OTG capable USB2 PHY has a reset line (which is shared with other
components, such as the USB3 PHY for example) and a clock (which are
both part of different registers). Add the properties
for the reset line and clocks as optional ones since not all PHYs have
them (currently only the OTG capable PHY is known to use these).

ARM System Control and Management Interface(SCMI)[1] is more flexible and
easily extensible than any of the existing interfaces.
Few existing as well as future ARM platforms provide micro-controllers
to abstract various power and other system management tasks which have
similar interfaces, both in terms of the functions that are provided by
them, and in terms of how requests are communicated to them.
There are quite a few protocols like ARM SCPI, TI SCI, QCOM RPM, Nvidia Tegra
BPMP, and so on already. This specification is to standardize and avoid any
further fragmentation in the design of such interface by various vendors.
The current SCMI driver implementation is very basic and initial support.
It lacks support for notifications, asynchronous/delayed response, perf/power
statistics region and sensor register region.
Mailbox is the only form of transport supported currently in the driver.
SCMI supports interrupt based mailbox communication, where, on completion
of the processing of a message, the caller receives an interrupt as well as
polling for completion.
SCMI is designed to minimize the dependency on the mailbox/transport
hardware. So in terms of SCMI, each channel in the mailbox includes
memory area, doorbell and completion interrupt.
However the doorbell and completion interrupt is highly mailbox dependent
which was bit of controversial as part of SCMI/mailbox discussions.
Arnd and me discussed about the few aspects of SCMI and the mailbox framework:
1. Use of mailbox framework for doorbell type mailbox controller:
- Such hardware may not require any data to be sent to signal the remote
about the presence of a message. The channel will have in-built
information on how to trigger the signal to the remote.
There are few mailbox controller drivers which are purely doorbell based.
e.g.QCOM IPC, STM, Tegra, ACPI PCC,..etc
2. Supporting other mailbox controller:
- SCMI just needs a mechanism to signal the remote firmware. Such
controller may need fixed message to be sent to trigger a doorbell.
In such case we may need to get that data from DT and pass the same
to the controller. It's not covered in the current DT binding, but
can be extended as optional property in future.
However handling notifications may be interesting on such mailbox, but
again there is no way to interpret what the data field(remote message)
means, it could be a bit mask or a number or don't-care.
Arnd mentioned that he doesn't like the way the mailbox binding deals
with doorbell-type hardware, but we do have quite a few precedent drivers
already and changing the binding to add a data field would not make it any
better, but could cause other problems. So he is happy with the status quo
of SCMI implementation.

WM8524 does not use I2C nor SPI, hence no 'reg' property is used,
so remove the unit address from the bindings example to conform.
This avoids users getting dtc warnings when they copy the
binding example to a real dts file.

Add support for r8a7743. The Renesas RZ/G1M(R8A7743)PCIe controller
is identical to the R-Car Gen2 family.
No driver change is needed due to the fallback compatible value
"renesas,pcie-rcar-gen2".
Adding the SoC-specific compatible values here has three purposes:
1. Document which SoCs have this hardware module,
2. Allow checkpatch to validate compatible values.
3. Allow the driver to support SoC specific implementations in future
as necessary.

This enables level resets on Meson8b SoCs. Level resets have been

This property is equivalent to "disable-wp" defined in

The TMIO MMC core calls mmc_of_parse(), and it sets
MMC_CAP2_NO_WRITE_PROTECT if "disable-wp" property is present.
We do not need a vendor-specific property to do the same thing.

from using it.

to "MANCH_R".

Add group configuration for uarts that are cut down
variants, the standard being full, i.e. all signals,
flow control, i.e. rx/tx and cts/rts, and rx/tx only.
This allows us to be more precise in which pins we're
actually using.
Unfortunately the existing naming scheme leaves things
to be desired, e.g. uart3grp0 means RX/TX and CTS/RTS,
yet uart0grp0 means all pins.
Since the exising suffixes have different meaning for
different uarts, and the fact that we cannot change
the name of existing groups, makes it hard to use a
descriptive name for the newly added groups.

AM335x and AM437x support various low power modes as documented
in section 8.1.4.3 of the AM335x Technical Reference Manual and
section 6.4.3 of the AM437x Technical Reference Manual.
DeepSleep0 mode offers the lowest power mode with limited
wakeup sources without a system reboot and is mapped as
the suspend state in the kernel. In this state, MPU and
PER domains are turned off with the internal RAM held in
retention to facilitate the resume process. As part of
the boot process, the assembly code is copied over to OCMCRAM
so it can be executed to turn of the EMIF and put DDR into self
refresh.
Both platforms have a Cortex-M3 (WKUP_M3) which assists the MPU
in DeepSleep0 entry and exit. WKUP_M3 takes care
of the clockdomain and powerdomain transitions based on the
intended low power state. MPU needs to load the appropriate
WKUP_M3 binary onto the WKUP_M3 memory space before it can
leverage any of the PM features like DeepSleep. This loading
is handled by the remoteproc driver wkup_m3_rproc.
Communication with the WKUP_M3 is handled by a wkup_m3_ipc
driver that exposes the specific PM functionality to be used
the PM code.
In the current implementation when the suspend process
is initiated, MPU interrupts the WKUP_M3 to let it know about
the intent of entering DeepSleep0 and waits for an ACK. When
the ACK is received MPU continues with its suspend process
to suspend all the drivers and then jumps to assembly in
OCMC RAM. The assembly code puts the external RAM in self-refresh
mode, gates the MPU clock, and then finally executes the WFI
instruction. Execution of the WFI instruction with MPU clock gated
triggers another interrupt to the WKUP_M3 which then continues
with the power down sequence wherein the clockdomain and
powerdomain transition takes place. As part of the sleep sequence,
WKUP_M3 unmasks the interrupt lines for the wakeup sources. WFI
execution on WKUP_M3 causes the hardware to disable the main
oscillator of the SoC and from here system remains in sleep state
until a wake source brings the system into resume path.
When a wakeup event occurs, WKUP_M3 starts the power-up
sequence by switching on the power domains and finally
enabling the clock to MPU. Since the MPU gets powered down
as part of the sleep sequence in the resume path ROM code
starts executing. The ROM code detects a wakeup from sleep
and then jumps to the resume location in OCMC which was
populated in one of the IPC registers as part of the suspend
sequence.
Code is based on work by Vaibhav Bedia.

revision has another clock input at the block boundary called the byte
interface clock. Specify this new clock in the binding.
A 10nm DSI PHY is used along with the controller. Add a compatible
string for it and specify its base address/regulator supply needs.

On some systems a delay is needed after switching on the clocks, to allow
the output to stabilize and avoid a popping noise at the beginning of
the recording. Add the optional device tree property 'wakeup-delay-ms'
and apply the specified delay after enabling the mic. A blocking delay
can't be applied in dmic_daiops_trigger() since the function is called
in atomic context. Instead use a DAPM event handler to set the enable
GPIO and apply the delay in the handler.

This commit adds all necessary compatibles and descriptions needed to
implement A83T HDMI pipeline.
Mixer is already properly described, so only compatible is added.
However, A83T TV TCON, which is connected to HDMI, doesn't have channel 0,
contrary to all TCONs currently described. Because of that, TCON
documentation is extended.
A83T features Synopsys DW HDMI controller with a custom PHY which looks
like Synopsys Gen2 PHY with few additions. Since there is no
documentation, needed properties were found out through experimentation
and reading BSP code.
At the end, example is added for newer SoCs, which feature DE2 and DW
HDMI.

Merge tag 'mips_4.16_2' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips
Pull MIPS fix from James Hogan:
"A single change (and associated DT binding update) to allow the
address of the MIPS Cluster Power Controller (CPC) to be chosen by DT,
which allows SMP to work on generic MIPS kernels where the bootloader
hasn't configured the CPC address (i.e. the new Ranchu platform)"
* tag 'mips_4.16_2' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips:
MIPS: CPC: Map registers using DT in mips_cpc_default_phys_base()
dt-bindings: Document mti,mips-cpc binding
The module autoloading can be triggered through the GPU core nodes
and the necessary platform device for the DRM toplevel device will
be instantiated on module init.
