1fbb2dc6f0 This round is dominated by NXP's i.MX clk drivers. We gained support for two or
three i.MX SoCs in here and that mostly means a lot of driver code and data.
 Beyond that platform, there are some new Mediatek, Amlogic, and Qualcomm clk
 drivers added in here, and then we get to the long tail of driver updates and
 non-critical fixes all around, including code for vendors such as Renesas,
 Rockchip, Nvidia, and Allwinner. Overall, the driver updates look normal.
 
 Beyond the usual driver updates we have an update to make registering OF based
 clk providers a little simpler when they're devices created as a child of a
 device backed by a node in DT. Drivers don't have to jump through hoops to
 unregister the provider upon driver removal anymore because the API does the
 right thing and uses the parent device DT node.
 
 Core:
  - Make devm_of_clk_add_hw_provider() use parent dt node if necessary
  - Various SPDX taggings
  - Mark clk_ops const when possible
 
 New Drivers:
  - NXP i.MX7ULP SoC clock support
  - NXP i.MX8QXP SoC clock support
  - NXP i.MX8MQ SoC clock support
  - NXP QorIQ T1023 SoC support
  - Qualcomm SDM845 audio subsystem clks
  - Qualcomm SDM845 GPU clck controllers
  - Qualcomm QCS404 RPM clk support
  - Mediatek MT7629 SoC clk controllers
  - Allwinner F1c100s SoC clocks
  - Allwinner H6 display engine clocks
  - Amlogic GX video clocks
  - Support for Amlogic meson8b CPU frequency scaling
  - Amlogic Meson8b CPU post-divider clocks
 
 Updates:
  - Proper suspend/resume on VersaClock5
  - Shrink code some with DEFINE_SHOW_ATTRIBUTE()
  - Register fixes for Rockchip rk3188 and rk3328
  - One new critical clock for Rockchip rk3188 and a fixed clock id (double used number)
  - New clock id for Rockchip rk3328
  - Amlogic Meson8/Meson8b video clock support
  - Amlogic got a clk-input helper and used it for the axg-audio clock driver
  - Sigma Delta modulation for the Allwinner A33 audio clocks
  - Support for CPEX (timer) clocks on various Renesas R-Car Gen3 and RZ/G2 SoCs
  - Support for SDHI HS400 clocks on early revisions of Renesas R-Car H3 and M3-W
  - Support for SDHI and USB clocks on Renesas RZ/A2
  - Support for RPC (SPI Multi I/O Bus Controller) clocks on Renesas R-Car V3M

0051db8218 spi: Updates for v4.21
The main thing this release has been a lot of work on the integration
 with SPI NOR flashes, there's been some specific support for a while for
 controller features designed to make them perform better but it's not
 worked out as well as hoped so the interface has been redesigned in a
 way that will hopefully do better - it's already been adopted by a
 number of additional controllers so things are looking good.  Otherwise
 most of the work has been driver specific:
 
  - Support for better integration with NOR flashes from Boris Brezillon
    and Yogesh Narayan Gaur plus usage of it in several drivers.
  - A big cleanup of the Rockchip driver from Emil Renner Berthing.
  - Lots of performance improvements for bcm2835 from Lukas Wunner.
  - Slave mode support for pxa2xx from Lubomir Rintel.
  - Support for Macronix MXIC, Mediatek MT7629 and MT8183, NPCM PSPI,
    and Renesas r8a77470.

79f20778fb regulator: Updates for v4.20
This has been a very busy release for the core, some fixes, one large new
 feature and a big bit of refactoring to update the GPIO API:
 
  - Support for coupled regulators from Dmitry Osipenko based on a prior
    attempt by Maciej Purski, allowing us to handle situations where the
    voltages on two regulators can't be too far apart from each other.
  - Conversion of the GPIO support in both drivers and the core to use
    GPIO descriptors rather than numbers, part of the overall project to
    remove GPIO numbers.
  - Support for standby mode suspend states from Andrei Stefanescu.
  - New drivers for Allwinner AXP209, Cirrus Logic Lochnagar and
    Microchip MPC16502.

d923fd6dc1 pwm: Changes for v4.21-rc1
Not a lot going on this cycle. There's some more cleanup going on and
 new driver support that was not quite ready in time for v4.21-rc1, but
 here are a few fixes and improvements that are good to go. The Kona PWM
 driver can now be built on the Cygnus architecture and the i.MX driver
 gained support for hardware readback. Some small fixes are provided for
 the clks711x and lpc18xx-sct drivers. Finally, to round things off some
 drivers are switched to SPDX license identifiers.

1e2af254ef Power management updates for 4.21-rc1
- Add sysadmin documentation for cpuidle (Rafael Wysocki).
 
  - Make it possible to specify a cpuidle governor from kernel
    command line, add new cpuidle state sysfs attributes for
    governor evaluation, and improve the "polling" idle state
    handling (Rafael Wysocki).
 
  - Fix the handling of the "required-opps" DT property in the
    operating performance points (OPP) framework, improve the
    integration of it with the generic power domains (genpd)
    framework, improve the handling of performance states in
    them and clean up the idle states vs performance states
    separation in genpd (Viresh Kumar, Ulf Hansson).
 
  - Add a cpufreq driver called "qcom-hw" for Qualcomm SoCs using
    a hardware engine to control CPU frequency transitions along
    with DT bindings for it (Taniya Das).
 
  - Fix an intel_pstate driver issue related to CPU offline and
    update the documentation of it (Srinivas Pandruvada).
 
  - Clean up the imx6q cpufreq driver (Anson Huang).
 
  - Add SPDX license IDs to cpufreq schedutil governor files (Daniel
    Lezcano).
 
  - Switch over the runtime PM framework to using high-res timers
    for device autosuspend to allow the control of it to be more
    precise (Vincent Guittot).
 
  - Disable non-wakeup ACPI GPEs during suspend-to-idle so that they
    don't prevent the system from reaching the target low-power state
    and simplify the suspend-to-idle handling on ACPI platforms
    without full Low-Power S0 Idle (LPS0) support (Rafael Wysocki).
 
  - Add system-wide suspend and resume support to the devfreq
    framework (Lukasz Luba).
 
  - Clean up the SmartReflex adaptive voltage scaling (AVS) driver and
    add an SPDX license ID to it (Nishanth Menon, Uwe Kleine-König,
    Thomas Meyer).
 
  - Get rid of code duplication by using the DEFINE_SHOW_ATTRIBUTE
    macro in some places, fix some DT node refcount leaks, and do
    some other janitorial cleanups (Yangtao Li).
 
  - Update the cpupower, intel_pstate_tracer and turbosat utilities
    (Abhishek Goel, Doug Smythies, Len Brown).

   - Clean up the imx6q cpufreq driver (Anson Huang).

   - Add SPDX license IDs to cpufreq schedutil governor files (Daniel
     Lezcano).

   - Switch over the runtime PM framework to using high-res timers for
     device autosuspend to allow the control of it to be more precise
     (Vincent Guittot).

   - Disable non-wakeup ACPI GPEs during suspend-to-idle so that they
     don't prevent the system from reaching the target low-power state
     and simplify the suspend-to-idle handling on ACPI platforms without
     full Low-Power S0 Idle (LPS0) support (Rafael Wysocki).

   - Add system-wide suspend and resume support to the devfreq framework
     (Lukasz Luba).

     add an SPDX license ID to it (Nishanth Menon, Uwe Kleine-König,
     Thomas Meyer).

   - Get rid of code duplication by using the DEFINE_SHOW_ATTRIBUTE
     macro in some places, fix some DT node refcount leaks, and do some
     other janitorial cleanups (Yangtao Li).

   - Update the cpupower, intel_pstate_tracer and turbosat utilities
     (Abhishek Goel, Doug Smythies, Len Brown)"

8e61e7b5c4 sound updates for 4.21
There are no intensive changes in both ALSA and ASoC core parts while
 rather most of changes are a bunch of driver fixes and updates.
 A large diff pattern appears in ASoC TI part which now merges both
 OMAP and DaVinci stuff, but the rest spreads allover the places.
 
 Note that this pull request includes also some updates for LED trigger
 and platform drivers for mute LEDs, appearing in the diffstat as well.
 
 Some highlights:
 
 ASoC:
 - Preparatory work for merging the audio-graph and audio-graph-scu
   cards
 - A merge of TI OMAP and DaVinci directories, as both product lines
   get merged together.  Also including a few architecture changes as
   well.
 - Major cleanups of the Maxim MAX9867 driver
 - Small fixes for tablets & co with Intel BYT/CHT chips
 - Lots of rsnd updates as usual
 - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
   RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
   controllers
 
 HD-audio:
 - Introduce audio-mute LED trigger for replacing the former hackish
   dynamic binding
 - Huawei WMI hotkey and mute LED support
 - Refactoring of PM code and display power controls
 - Headset button support in the generic jack code
 - A few updates for Tegra
 - Fixups for HP EliteBook and ASUS UX391UA
 - Lots of updates for Intel ASoC HD-audio, including the improved DSP
   detection and the fallback binding from ASoC SST to legacy HD-audio
   controller drivers
 
 Others:
 - Updates for FireWire TASCAM and Fireface devices, some other fixes
 - A few potential Spectre v1 fixes that are all trivial

c79b411eaa crypto: skcipher - remove remnants of internal IV generators
Remove dead code related to internal IV generators, which are no longer
used since they've been replaced with the "seqiv" and "echainiv"
templates.  The removed code includes:

- The "givcipher" (GIVCIPHER) algorithm type.  No algorithms are
  registered with this type anymore, so it's unneeded.

- The "const char *geniv" member of aead_alg, ablkcipher_alg, and
  blkcipher_alg.  A few algorithms still set this, but it isn't used
  anymore except to show via /proc/crypto and CRYPTO_MSG_GETALG.
  Just hardcode "<default>" or "<none>" in those cases.

- The 'skcipher_givcrypt_request' structure, which is never used.

fed8b7e366 dt-bindings: tegra186-hsp: Add shared mailboxes
Shared mailboxes are a mechanism to transport data from one processor in
the system to another. They are bidirectional links with both a producer
and a consumer. Interrupts are used to let the consumer know when data
was written to the mailbox by the producer, and to let the producer know
when the consumer has read the data from the mailbox. These interrupts
are mapped to one or more "shared interrupts". Typically each processor
in the system owns one of these shared interrupts.

Add documentation to the device tree bindings about how clients can use
mailbox specifiers to request a specific shared mailbox and select which
direction they drive. Also document how to specify the shared interrupts
in addition to the existing doorbell interrupt.

As pointed by Rob, CRU is a kind of block that can't be guaranteed to
have everything exposed as subnodes. It's a set of various registers
that aren't tied to any single device. It could be described much more
accurately as MFD (Multi-Function Device).

Some hardware blocks may indeed want to access a register or two of the
CRU which requires describing it as the "syscon".

While at it replace exmple node name with the standard "pinctrl" (also
pointed out by Rob).

a4e92ce8e4 powerpc/fadump: Reservationless firmware assisted dump
One of the primary issues with Firmware Assisted Dump (fadump) on Power
is that it needs a large amount of memory to be reserved. On large
systems with TeraBytes of memory, this reservation can be quite
significant.

In some cases, fadump fails if the memory reserved is insufficient, or
if the reserved memory was DLPAR hot-removed.

In the normal case, post reboot, the preserved memory is filtered to
extract only relevant areas of interest using the makedumpfile tool.
While the tool provides flexibility to determine what needs to be part
of the dump and what memory to filter out, all supported distributions
default this to "Capture only kernel data and nothing else".

We take advantage of this default and the Linux kernel's Contiguous
Memory Allocator (CMA) to fundamentally change the memory reservation
model for fadump.

Instead of setting aside a significant chunk of memory nobody can use,
this patch uses CMA instead, to reserve a significant chunk of memory
that the kernel is prevented from using (due to MIGRATE_CMA), but
applications are free to use it. With this fadump will still be able
to capture all of the kernel memory and most of the user space memory
except the user pages that were present in CMA region.

Essentially, on a P9 LPAR with 2 cores, 8GB RAM and current upstream:
[root@zzxx-yy10 ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:           7557         193        6822          12         541        6725
Swap:          4095           0        4095

With this patch:
[root@zzxx-yy10 ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:           8133         194        7464          12         475        7338
Swap:          4095           0        4095

Changes made here are completely transparent to how fadump has
traditionally worked.

Thanks to Aneesh Kumar and Anshuman Khandual for helping us understand
CMA and its usage.

- Handle case where CMA reservation spans nodes.

Intel Wired LAN Driver Updates 2018-12-20

This series contains updates to e100, igb, ixgbe, i40e and ice drivers.

I replaced spinlocks for mutex locks to reduce the latency on CPU0 for
igb when updating the statistics.  This work was based off a patch
provided by Jan Jablonsky, which was against an older version of the igb
driver.

Jesus adjusts the receive packet buffer size from 32K to 30K when
running in QAV mode, to stay within 60K for total packet buffer size for
igb.

Vinicius adds igb kernel documentation regarding the CBS algorithm and
its implementation in the i210 family of NICs.

YueHaibing from Huawei fixed the e100 driver that was potentially
passing a NULL pointer, so use the kernel macro IS_ERR_OR_NULL()
instead.

Konstantin Khorenko fixes i40e where we were not setting up the
neigh_priv_len in our net_device, which caused the driver to read beyond
the neighbor entry allocated memory.

Miroslav Lichvar extends the PTP gettime() to read the system clock by
adding support for PTP_SYS_OFFSET_EXTENDED ioctl in i40e.

Young Xiao fixed the ice driver to only enable NAPI on q_vectors that
actually have transmit and receive rings.

Kai-Heng Feng fixes an igb issue that when placed in suspend mode, the
NIC does not wake up when a cable is plugged in.  This was due to the
driver not setting PME during runtime suspend.

Stephen Douthit enables the ixgbe driver allow DSA devices to use the
MII interface to talk to switches.

The BCM4330 is a 802.11 a/b/g/n WiFi + Bluetooth 4.0 chip from Broadcom.
It is found in the Ampak AP6330 WiFi+BT module. The partiular one I have
identifies as BCM4330B1 for Bluetooth and BCM4330/4 for WiFi.

It is unclear if the AP6330 module uses this revision of the BCM4330, or
if there are multiple revisions. The module does not have revision
markings. This patch elects to use just BCM4330 for the compatible
string.

6ae81eebde dt-bindings: net: broadcom-bluetooth: Fix external clock names
The Broadcom Bluetooth controllers can take up to two external clocks:
an external frequency reference, substituting the main crystal, and a
LPO clock at 32.768 kHz substituting the internal LPO clock.

In particular, the external LPO clock must be used when the controller
does not have NVRAM connected, and the main reference frequency is not
the default 20 MHz. This is described in detail in the datasheet.

The original "extclk" clock name is ambiguous as to which of these it
refers to, and some designs might even require both.

This patch deprecates the existing name, and adds "txco" and "lpo".

The only remaining user of board_time_init() is the of-generic
machine, and that just calls the global timer_init() function.
Calling that one has no effect on non-DT platforms, so we can
simply call it unconditionally in place of board_time_init().

5580b4a1a8 Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity into next-integrity
From Mimi:

In Linux 4.19, a new LSM hook named security_kernel_load_data was
upstreamed, allowing LSMs and IMA to prevent the kexec_load
syscall.  Different signature verification methods exist for verifying
the kexec'ed kernel image.  This pull request adds additional support
in IMA to prevent loading unsigned kernel images via the kexec_load
syscall, independently of the IMA policy rules, based on the runtime
"secure boot" flag.  An initial IMA kselftest is included.

In addition, this pull request defines a new, separate keyring named
".platform" for storing the preboot/firmware keys needed for verifying
the kexec'ed kernel image's signature and includes the associated IMA
kexec usage of the ".platform" keyring.

(David Howell's and Josh Boyer's patches for reading the
preboot/firmware keys, which were previously posted for a different
use case scenario, are included here.)

bdb48e4c7d dt-bindings: serial: 8250: Add rate limit for serial port input overruns
When a serial port continuously experiences input overrun from
(1) continuous receive characters from remote and or (2) hardware
issues, its interrupt handler can preempt other tasks especially
when the system is busy (ie. boot up period). This can cause other
tasks to get starved of processing time from the CPU.

When this dts binding is enabled and input overrun on the serial port
is detected, serial port receive will be throttled to give some breathing
room for processing other tasks. Value provided will be in milliseconds.

&serial0{
	overrun-throttle-ms = <500>;

Commit 26a4f38d13 ("dt-bindings: mmc: sdhci-of-arasan: Add new
compatible for AM654 MMC PHY") added a new compatible for supporting
controllers on TI's AM65x SOCs. It turns out that the controller is
not compatible with the arasan driver's phy and consumer model as it
requires some phy registers for core sdhci functionality. This calls
for the binding to branch out to a new driver.

Therefore, add a deprecated message for the ti,am654-sdhci-5.1 binding.

2bc39970e9 x86/kvm/hyper-v: Introduce KVM_GET_SUPPORTED_HV_CPUID
With every new Hyper-V Enlightenment we implement we're forced to add a
KVM_CAP_HYPERV_* capability. While this approach works it is fairly
inconvenient: the majority of the enlightenments we do have corresponding
CPUID feature bit(s) and userspace has to know this anyways to be able to
expose the feature to the guest.

Add KVM_GET_SUPPORTED_HV_CPUID ioctl (backed by KVM_CAP_HYPERV_CPUID, "one
cap to rule them all!") returning all Hyper-V CPUID feature leaves.

Using the existing KVM_GET_SUPPORTED_CPUID doesn't seem to be possible:
Hyper-V CPUID feature leaves intersect with KVM's (e.g. 0x40000000,
0x40000001) and we would probably confuse userspace in case we decide to
return these twice.

KVM_CAP_HYPERV_CPUID's number is interim: we're intended to drop
KVM_CAP_HYPERV_STIMER_DIRECT and use its number instead.

ASoC: q6asm-dai: dt-bindings: Add support to compress dais
This patch adds board specific bindings required for dais, In particular
for compressed dais and dai direction.

Board specific setup involves setting up some of dais as compressed dais
and also specify direction of any dai. Some of the dais might only
support capture/playback depending on the board level wiring.

These two new dt properties will allow such flexibilty at board level dts.

2a31b9db15 kvm: introduce manual dirty log reprotect
There are two problems with KVM_GET_DIRTY_LOG.  First, and less important,
it can take kvm->mmu_lock for an extended period of time.  Second, its user
can actually see many false positives in some cases.  The latter is due
to a benign race like this:

  1. KVM_GET_DIRTY_LOG returns a set of dirty pages and write protects
     them.
  2. The guest modifies the pages, causing them to be marked ditry.
  3. Userspace actually copies the pages.
  4. KVM_GET_DIRTY_LOG returns those pages as dirty again, even though
     they were not written to since (3).

This is especially a problem for large guests, where the time between
(1) and (3) can be substantial.  This patch introduces a new
capability which, when enabled, makes KVM_GET_DIRTY_LOG not
write-protect the pages it returns.  Instead, userspace has to
explicitly clear the dirty log bits just before using the content
of the page.  The new KVM_CLEAR_DIRTY_LOG ioctl can also operate on a
64-page granularity rather than requiring to sync a full memslot;
this way, the mmu_lock is taken for small amounts of time, and
only a small amount of time will pass between write protection
of pages and the sending of their content.

0f5ab411f5 dt-bindings: clock: add imx8qxp lpcg clock binding
The Low-Power Clock Gate (LPCG) modules contain a local programming
model to control the clock gates for the peripherals. An LPCG module
is used to locally gate the clocks for the associated peripheral.

Note:
This level of clock gating is provided after the clocks are generated
by the SCU resources and clock controls. Thus even if the clock is
enabled by these control bits, it might still not be running based
on the base resource.

7c813152cf dt-bindings/gic-v3: Add msm8996 compatible string
Access to GICR_WAKER is restricted on msm8996 SoC in Hypervisor.
There are many devices out there with this restriction in place
and there has been no update to this firmware since last few years,
making those devices totally unusable for upstream development.

IIDR register value conflicts with other SoCs, using compatible seems
to be the only way to apply quirks required for msm8996 based SoCs.

Without this quirk many qcom SoCs (atleast 3 that I know) are
unable to boot mainline.

dt-bindings: mfd: axp20x: Add software based soft_start for AXP209 LDO3
In the past, there have been words on various lists that if LDO3 is
disabled in u-boot, but enabled in the DTS, the axp209 driver would
fail to continue/hang. Several enable/disable patches have been
issues to devicetree's in both the kernel and u-boot to address
this issue.

What really happened however, was that the AXP209 shuts down without
a notice and without setting an interrupt. This is caused when LDO3
gets overloaded, for example with large capacitors on the LDO3 output.

Normally, we would expect that AXP209 would source 200 mA as per
datasheet and set and trigger an interrupt when being overloaded.
For some reason however, this does not happen.

As a work-around, implement software-based 'regulator-soft-start'
property for AXP209 LDO3 regulator, which is used to first bring up
the LDO3 to the lowest possible voltage and then enable the LDO.

After that, we can set the requested voltage as usual.

Combining this setting with the regulator-ramp-delay allows LDO3 to
come up slowly and staggered, potentially reducing overall inrush current.

dt-bindings: mfd: axp20x: add support for regulator-ramp-delay for AXP209
The AXP209 supports ramping up voltages on several regulators such as
DCDC2 and LDO3, therefore we can use the standard 'regulator-ramp-delay'
property for those 2 regulators.

Note that the voltage ramp only works when the regulator is already
enabled. E.g. when going from say 0.7 V to 3.6 V.

When turning on the regulator, no voltage ramp is performed in hardware.

What this means, is that if the bootloader brings up the voltage at 0.7 V,
the ramp delay property is properly applied. If however, the bootloader
leaves the power off, no ramp delay is applied when the power is
enabled by the regulator framework.

00ce8a8000 dt-bindings: Add a writing DT schemas how-to and annotated example
Add a how-to doc on writing DT schema documentation. This gives a
description of each section and details on how to validate the DT schema
file. The DT schema are written using json-schema vocabulary in a YAML
encoded document. Using jsonschema gives us access to existing tooling.
A YAML encoding gives us something easy to edit. The example is
annotated to help explain what each section does.

This example is just the tip of the iceberg, but is it the part most
developers writing bindings will interact with. Backing all this up
are meta-schema (to validate the binding schemas), some DT core schema,
YAML encoded DT output with dtc, and a small number of python scripts to
run validation.

4f0e3a57d6 kbuild: Add support for DT binding schema checks
This adds the build infrastructure for checking DT binding schema
documents and validating dts files using the binding schema.

Check DT binding schema documents:
make dt_binding_check

Build dts files and check using DT binding schema:
make dtbs_check

Optionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to
use for validation. This makes it easier to find and fix errors
generated by a specific schema.

Currently, the validation targets are separate from a normal build to
avoid a hard dependency on the external DT schema project and because
there are lots of warnings generated.

Merge tag 'media/v4.20-5' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media fixes from Mauro Carvalho Chehab:

 - one regression at vsp1 driver

 - some last time changes for the upcoming request API logic and for
   stateless codec support. As the stateless codec "cedrus" driver is at
   staging, don't apply the MPEG controls as part of the main V4L2 API,
   as those may not be ready for production yet.

* tag 'media/v4.20-5' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media:
  media: Add a Kconfig option for the Request API
  media: extended-controls.rst: add note to the MPEG2 state controls
  media: mpeg2-ctrls.h: move MPEG2 state controls to non-public header
  media: vicodec: set state resolution from raw format
  media: vivid: drop v4l2_ctrl_request_complete() from start_streaming
  media: vb2: don't unbind/put the object when going to state QUEUED
  media: vb2: keep a reference to the request until dqbuf
  media: vb2: skip request checks for VIDIOC_PREPARE_BUF

04dab58a39 cpuidle: Add 'above' and 'below' idle state metrics
Add two new metrics for CPU idle states, "above" and "below", to count
the number of times the given state had been asked for (or entered
from the kernel's perspective), but the observed idle duration turned
out to be too short or too long for it (respectively).

These metrics help to estimate the quality of the CPU idle governor
in use.

5ac93d0c5d USB changes for v4.21
So it looks like folks are interested in dwc3 again. Almost 64% of the
 changes are in dwc3 this time around with some other bits in gadget
 functions and dwc2.
 
 There are two important parts here: a. removal of the waitqueue from
 dwc3's dequeue implementation, which will guarantee that gadget
 functions can dequeue from any context and; b. better method for
 starting isochronous transfers to avoid, as much as possible, missed
 isoc frames.
 
 Apart from these, we have the usual set of non-critical fixes and new
 features all over the place.

Evan Green
d21aafe9a4 dt-bindings: phy-qcom-qmp: Move #clock-cells to child
The phy-qcom-qmp bindings specified #clock-cells as 1. This was never used
because of_clk_add_provider() was never called, so there was no way anybody
could reference these clocks from DT. Furthermore, even if they could be
accessed, the bindings never specified what should go in that additional
cell.

Fix these incomplete and broken bindings. Move the #clock-cells into the
child node, since that is the actual clock provider, and not all
instances of qcom-qmp-phy are clock providers. Also set #clock-cells to
zero, since there's nothing to pass to it.
