710b65335c i2c: parport-light: remove driver 
The justification of a light version of the parport driver was less
overhead for embedded systems. Well, today, even if an embedded system
still has a parport, it surely can handle the fully-fledged parport
driver. Remove it to reduce the maintenance burden.

769071ac9f ns: Introduce Time Namespace 
Time Namespace isolates clock values.

The kernel provides access to several clocks CLOCK_REALTIME,
CLOCK_MONOTONIC, CLOCK_BOOTTIME, etc.

CLOCK_REALTIME
      System-wide clock that measures real (i.e., wall-clock) time.

CLOCK_MONOTONIC
      Clock that cannot be set and represents monotonic time since
      some unspecified starting point.

CLOCK_BOOTTIME
      Identical to CLOCK_MONOTONIC, except it also includes any time
      that the system is suspended.

For many users, the time namespace means the ability to changes date and
time in a container (CLOCK_REALTIME). Providing per namespace notions of
CLOCK_REALTIME would be complex with a massive overhead, but has a dubious
value.

But in the context of checkpoint/restore functionality, monotonic and
boottime clocks become interesting. Both clocks are monotonic with
unspecified starting points. These clocks are widely used to measure time
slices and set timers. After restoring or migrating processes, it has to be
guaranteed that they never go backward. In an ideal case, the behavior of
these clocks should be the same as for a case when a whole system is
suspended. All this means that it is required to set CLOCK_MONOTONIC and
CLOCK_BOOTTIME clocks, which can be achieved by adding per-namespace
offsets for clocks.

A time namespace is similar to a pid namespace in the way how it is
created: unshare(CLONE_NEWTIME) system call creates a new time namespace,
but doesn't set it to the current process. Then all children of the process
will be born in the new time namespace, or a process can use the setns()
system call to join a namespace.

This scheme allows setting clock offsets for a namespace, before any
processes appear in it.

All available clone flags have been used, so CLONE_NEWTIME uses the highest
bit of CSIGNAL. It means that it can be used only with the unshare() and
the clone3() system calls.

[ tglx: Adjusted paragraph about clone3() to reality and massaged the
  	changelog a bit. ]

76db5a27a8 bootconfig: Add Extra Boot Config support 
Extra Boot Config (XBC) allows admin to pass a tree-structured
boot configuration file when boot up the kernel. This extends
the kernel command line in an efficient way.

Boot config will contain some key-value commands, e.g.

key.word = value1
another.key.word = value2

It can fold same keys with braces, also you can write array
data. For example,

key {
   word1 {
      setting1 = data
      setting2
   }
   word2.array = "val1", "val2"
}

User can access these key-value pair and tree structure via
SKC APIs.

159348784f x86/vmx: Introduce VMX_FEATURES_* 
Add a VMX-specific variant of X86_FEATURE_* flags, which will eventually
supplant the synthetic VMX flags defined in cpufeatures word 8.  Use the
Intel-defined layouts for the major VMX execution controls so that their
word entries can be directly populated from their respective MSRs, and
so that the VMX_FEATURE_* flags can be used to define the existing bit
definitions in asm/vmx.h, i.e. force developers to define a VMX_FEATURE
flag when adding support for a new hardware feature.

The majority of Intel's (and compatible CPU's) VMX capabilities are
enumerated via MSRs and not CPUID, i.e. querying /proc/cpuinfo doesn't
naturally provide any insight into the virtualization capabilities of
VMX enabled CPUs.  Commit

  e38e05a858 ("x86: extended "flags" to show virtualization HW feature
		 in /proc/cpuinfo")

attempted to address the issue by synthesizing select VMX features into
a Linux-defined word in cpufeatures.

Lack of reporting of VMX capabilities via /proc/cpuinfo is problematic
because there is no sane way for a user to query the capabilities of
their platform, e.g. when trying to find a platform to test a feature or
debug an issue that has a hardware dependency.  Lack of reporting is
especially problematic when the user isn't familiar with VMX, e.g. the
format of the MSRs is non-standard, existence of some MSRs is reported
by bits in other MSRs, several "features" from KVM's point of view are
enumerated as 3+ distinct features by hardware, etc...

The synthetic cpufeatures approach has several flaws:

  - The set of synthesized VMX flags has become extremely stale with
    respect to the full set of VMX features, e.g. only one new flag
    (EPT A/D) has been added in the the decade since the introduction of
    the synthetic VMX features.  Failure to keep the VMX flags up to
    date is likely due to the lack of a mechanism that forces developers
    to consider whether or not a new feature is worth reporting.

  - The synthetic flags may incorrectly be misinterpreted as affecting
    kernel behavior, i.e. KVM, the kernel's sole consumer of VMX,
    completely ignores the synthetic flags.

  - New CPU vendors that support VMX have duplicated the hideous code
    that propagates VMX features from MSRs to cpufeatures.  Bringing the
    synthetic VMX flags up to date would exacerbate the copy+paste
    trainwreck.

Define separate VMX_FEATURE flags to set the stage for enumerating VMX
capabilities outside of the cpu_has() framework, and for adding
functional usage of VMX_FEATURE_* to help ensure the features reported
via /proc/cpuinfo is up to date with respect to kernel recognition of
VMX capabilities.

6c39e015f8 devlink: convert driver-specific files to reStructuredText 
Several drivers document what parameters they support in
a devlink-params-*.txt file. This file is supposed to contain both the
list of generic parameters implemented by the driver, as well as a list
of driver-specific parameters and their descriptions.

It would also be good if the driver documentation included other
driver-specific implementations, such as info versions, devlink
regions, and so forth.

Convert all of these documentation files to reStructuredText, and rename
them to just the driver name. Future changes will include other
driver-specific implementations. Each file will contain a table for the
generic parameters implemented, as well as a separate table for the
driver-specific parameters.

Future sections such as for devlink info versions will be added to these
files. This avoids creating additional devlink-<feature>-<driver> files
for each devlink feature, reducing clutter in the documentation folder.

   - Allow pm_ops to disable device completely allowing regulator power down.
 * bma180
   - Enable basic regulator support.

 * st_lsm6dsx
   - white space fixes.
   - Mark some constants that aren't always used as __maybe_unused.
   - Drop of ID table guards as they just pervent use under ACPI.
   - Switch to device properties to allow ACPI usage.
 * st_uvis25
   - Drop acpi.h include as no ACPI APIs used.

* st_lsm6dsx
  - Enable the sensor-hub support for lsm6dsm. Includes various reworks to
    allow this.

Cleanups and minor fixes

* Subsystem wide
  - Tidy up indentation in Kconfig and fix alphabetical order of AD7091R5.
  - Drop linux/gpio.h and linux/of_gpio.h from drivers that don't use them.
* ad7266
  - Convert to GPIO descriptors.
* ad7303
  - Avoid a dance with checking if the regulator is supplied by just
    using the optional request interface.
* ad7887
  - Simplify channel specification assignment to enable adding more devices.
* ad7923
  - Drop some unused and largely pointless defines of BOB_N==N variety.
  - Tidy up checkpatch warnings.
  - Add missing of_device_id table.
* adf4350
  - Convert to GPIO descriptors.
* ak8975
  - Convert to GPIO descriptors.
* ADIS library and drivers
  - Expand scope of txrx_lock to cover all state and rename as state_lock
  - Add unlocked read / write to allow grouping of consecutive calls under
    single lock / unlock.
  - Add unlocked check_status, reset to allow grouping under single
    lock / unlock.
  - Remove remaining uses of core mlock for local state protection.
    mlock should never be used directly as it protects tightly defined
    core IIO device management state.
* adis16240
  - Enforce only supported SPI mode on driver load + add DT binding doc.
* atlas-ph-sensor
  - Rename to atlas-sensor given it now covers things beyond ph sensors.
* bma180
  - Use local dev variable to tidy up code.
  - Use c99 style explicity .member assignment to make driver more readable.
* bmp280
  - Drop ACPI support. No evidence this was used and appropriate ID is not
    registered.
  - Allow ACPI to bind device via PRP0001
* dmaengine buffer
  - Use dma_request_chan instead of dma_request_slave_channel_reason as that
    ABI is going away.
  - Add module info to avoid tainting the kernel.
* hts221
  - Avoid magic number defines when only used to fill structure elements
    that are self describing.
* lm3533
  - Drop a stray semicolon.
* max9611
  - Cleanup enum handling to be more resilient to future changes.
* mpu6050
  - Delete MPU9150 from supported SPI devices as doesn't provide SPI.
  - Select I2C_MUX again after kbuild issue fixed elsewhere.
* stm32-timer
  - Drop an unnecessary register update.
* ssp_sensors
  - Convert to GPIO descriptors.
* st_sensors
  - drop !CONFIG_ACPI defines as ACPI_PTR() will stop them being used
    anyway.
  - Make default platform data structures __maybe_unsued.
  - Fill in some missing kernel-doc function parameters.
* st_lsm6dsx
  - white space fixes.
  - Mark some constants that aren't always used as __maybe_unused.
  - Drop of ID table guards as they just pervent use under ACPI.
  - Switch to device properties to allow ACPI usage.
* st_uvis25
  - Drop acpi.h include as no ACPI APIs used.
* ti-ads1015
  - Drop legacy platform data as no one seems to be using it.
  - Use the device property API instead of OF specific.
* ti-ads7950
  - typo fix in error message.

89b223bfb8 selinux: deprecate disabling SELinux and runtime 
Deprecate the CONFIG_SECURITY_SELINUX_DISABLE functionality.  The
code was originally developed to make it easier for Linux
distributions to support architectures where adding parameters to the
kernel command line was difficult.  Unfortunately, supporting runtime
disable meant we had to make some security trade-offs when it came to
the LSM hooks, as documented in the Kconfig help text:

  NOTE: selecting this option will disable the '__ro_after_init'
  kernel hardening feature for security hooks.   Please consider
  using the selinux=0 boot parameter instead of enabling this
  option.

Fortunately it looks as if that the original motivation for the
runtime disable functionality is gone, and Fedora/RHEL appears to be
the only major distribution enabling this capability at build time
so we are now taking steps to remove it entirely from the kernel.
The first step is to mark the functionality as deprecated and print
an error when it is used (what this patch is doing).  As Fedora/RHEL
makes progress in transitioning the distribution away from runtime
disable, we will introduce follow-up patches over several kernel
releases which will block for increasing periods of time when the
runtime disable is used.  Finally we will remove the option entirely
once we believe all users have moved to the kernel cmdline approach.

0e194d9da1 Documentation: riscv: add patch acceptance guidelines 
Formalize, in kernel documentation, the patch acceptance policy for
arch/riscv.  In summary, it states that as maintainers, we plan to
only accept patches for new modules or extensions that have been
frozen or ratified by the RISC-V Foundation.

We've been following these guidelines for the past few months.  In the
meantime, we've received quite a bit of feedback that it would be
helpful to have these guidelines formally documented.

Based on a suggestion from Matthew Wilcox, we also add a link to this
file to Documentation/process/index.rst, to make this document easier
to find.  The format of this document has also been changed to align
to the format outlined in the maintainer entry profiles, in accordance
with comments from Jon Corbet and Dan Williams.

31f715dd48 media: MAINTAINERS: Orphan img-ir driver 
I haven't been active for 18 months, and don't have the hardware set up
to test the img-ir driver, so mark it as orphaned and remove myself as
maintainer.

I used to test this driver using a Minimorph board with Meta based
TZ1090 SoC, but the Meta arch port is long gone from the kernel. The
only remaining platform in-tree using this driver is the Imagination
Pistachio SoC, and the only Pistachio based board with DTS in-tree (MIPS
Creator Ci40) doesn't bring the IR out.

However I presume the IP persists under the guardianship of Sondrel, and
its possible current & future SoCs/boards may continue to use this IP.

9209fb5189 riscv: move sifive_l2_cache.c to drivers/soc 
The sifive_l2_cache.c is in no way related to RISC-V architecture
memory management.  It is a little stub driver working around the fact
that the EDAC maintainers prefer their drivers to be structured in a
certain way that doesn't fit the SiFive SOCs.

Move the file to drivers/soc and add a Kconfig option for it, as well
as the whole drivers/soc boilerplate for CONFIG_SOC_SIFIVE.

bf6910abf5 power: avs: Add support for CPR (Core Power Reduction) 
CPR (Core Power Reduction) is a technology that reduces core power on a
CPU or other device. It reads voltage settings in efuse from product
test process as initial settings.
Each OPP corresponds to a "corner" that has a range of valid voltages
for a particular frequency. While the device is running at a particular
frequency, CPR monitors dynamic factors such as temperature, etc. and
adjusts the voltage for that frequency accordingly to save power
and meet silicon characteristic requirements.

This driver is based on an RFC by Stephen Boyd[1], which in turn is
based on work by others on codeaurora.org[2].

ea200dec51 ARM: SoC fixes 
I didn't get a batch in this weekend, so here's what we queued up last
 week and today.
 
  - A couple of defconfigs add back debugfs -- it used to be implicitly
  enabled through CONFIG_TRACING, but 0e4a459f56 ("tracing: Remove
  unnecessary DEBUG_FS dependency") removed that.
 
  - The rest are mostly minor fixlets of the usual kind; some DT tweaks,
  a headerfile refactor that needs a build fix now, etc.

This chip is similar to the LTC2497 ADC, it just uses SPI instead of I2C
and so has a slightly different protocol. Only the actual hardware
access is different. The spi protocol is different enough to not be able
to map the differences via a regmap.

Also generalize the entry in MAINTAINER to cover the newly introduced

c02a81fba7 dma-buf: Add dma-buf heaps framework 
This framework allows a unified userspace interface for dma-buf
exporters, allowing userland to allocate specific types of memory
for use in dma-buf sharing.

Each heap is given its own device node, which a user can allocate
a dma-buf fd from using the DMA_HEAP_IOC_ALLOC.

This code is an evoluiton of the Android ION implementation,
and a big thanks is due to its authors/maintainers over time
for their effort:
  Rebecca Schultz Zavin, Colin Cross, Benjamin Gaignard,
  Laura Abbott, and many other contributors!

====================
pull-request: can 2019-12-08

this is a pull request of 13 patches for net/master.

The first two patches are by Dan Murphy. He adds himself as a maintainer to the
m-can MMIO and tcan SPI driver.

The next two patches the j1939 stack. The first one is by Oleksij Rempel and
fixes a locking problem found by the syzbot, the second one is by me an fixes a
mistake in the documentation.

Srinivas Neeli fixes missing RX CAN packets on CANFD2.0 in the xilinx driver.

Sean Nyekjaer fixes a possible deadlock in the the flexcan driver after
suspend/resume. Joakim Zhang contributes two patches for the flexcan driver
that fix problems with the low power enter/exit.

The next 4 patches all target the tcan part of the m_can driver. Sean Nyekjaer
adds the required delay after reset and fixes the device tree binding example.
Dan Murphy's patches make the wake-gpio optional.

In the last patch Xiaolong Huang fixes several kernel memory info leaks to the
USB device in the kvaser_usb_leaf driver.

e7096c131e net: WireGuard secure network tunnel 
WireGuard is a layer 3 secure networking tunnel made specifically for
the kernel, that aims to be much simpler and easier to audit than IPsec.
Extensive documentation and description of the protocol and
considerations, along with formal proofs of the cryptography, are
available at:

  * https://www.wireguard.com/
  * https://www.wireguard.com/papers/wireguard.pdf

This commit implements WireGuard as a simple network device driver,
accessible in the usual RTNL way used by virtual network drivers. It
makes use of the udp_tunnel APIs, GRO, GSO, NAPI, and the usual set of
networking subsystem APIs. It has a somewhat novel multicore queueing
system designed for maximum throughput and minimal latency of encryption
operations, but it is implemented modestly using workqueues and NAPI.
Configuration is done via generic Netlink, and following a review from
the Netlink maintainer a year ago, several high profile userspace tools
have already implemented the API.

This commit also comes with several different tests, both in-kernel
tests and out-of-kernel tests based on network namespaces, taking profit
of the fact that sockets used by WireGuard intentionally stay in the
namespace the WireGuard interface was originally created, exactly like
the semantics of userspace tun devices. See wireguard.com/netns/ for
pictures and examples.

The source code is fairly short, but rather than combining everything
into a single file, WireGuard is developed as cleanly separable files,
making auditing and comprehension easier. Things are laid out as
follows:

  * noise.[ch], cookie.[ch], messages.h: These implement the bulk of the
    cryptographic aspects of the protocol, and are mostly data-only in
    nature, taking in buffers of bytes and spitting out buffers of
    bytes. They also handle reference counting for their various shared
    pieces of data, like keys and key lists.

  * ratelimiter.[ch]: Used as an integral part of cookie.[ch] for
    ratelimiting certain types of cryptographic operations in accordance
    with particular WireGuard semantics.

  * allowedips.[ch], peerlookup.[ch]: The main lookup structures of
    WireGuard, the former being trie-like with particular semantics, an
    integral part of the design of the protocol, and the latter just
    being nice helper functions around the various hashtables we use.

  * device.[ch]: Implementation of functions for the netdevice and for
    rtnl, responsible for maintaining the life of a given interface and
    wiring it up to the rest of WireGuard.

  * peer.[ch]: Each interface has a list of peers, with helper functions
    available here for creation, destruction, and reference counting.

  * socket.[ch]: Implementation of functions related to udp_socket and
    the general set of kernel socket APIs, for sending and receiving
    ciphertext UDP packets, and taking care of WireGuard-specific sticky
    socket routing semantics for the automatic roaming.

  * netlink.[ch]: Userspace API entry point for configuring WireGuard
    peers and devices. The API has been implemented by several userspace
    tools and network management utility, and the WireGuard project
    distributes the basic wg(8) tool.

  * queueing.[ch]: Shared function on the rx and tx path for handling
    the various queues used in the multicore algorithms.

  * send.c: Handles encrypting outgoing packets in parallel on
    multiple cores, before sending them in order on a single core, via
    workqueues and ring buffers. Also handles sending handshake and cookie
    messages as part of the protocol, in parallel.

  * receive.c: Handles decrypting incoming packets in parallel on
    multiple cores, before passing them off in order to be ingested via
    the rest of the networking subsystem with GRO via the typical NAPI
    poll function. Also handles receiving handshake and cookie messages
    as part of the protocol, in parallel.

  * timers.[ch]: Uses the timer wheel to implement protocol particular
    event timeouts, and gives a set of very simple event-driven entry
    point functions for callers.

  * main.c, version.h: Initialization and deinitialization of the module.

  * selftest/*.h: Runtime unit tests for some of the most security
    sensitive functions.

  * tools/testing/selftests/wireguard/netns.sh: Aforementioned testing
    script using network namespaces.

This commit aims to be as self-contained as possible, implementing
WireGuard as a standalone module not needing much special handling or
coordination from the network subsystem. I expect for future
optimizations to the network stack to positively improve WireGuard, and
vice-versa, but for the time being, this exists as intentionally
standalone.

We introduce a menu option for CONFIG_WIREGUARD, as well as providing a
verbose debug log and self-tests via CONFIG_WIREGUARD_DEBUG.

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Warn if a host bridge has no NUMA info (Yunsheng Lin)

   - Add PCI_STD_NUM_BARS for the number of standard BARs (Denis
     Efremov)

  Resource management:

   - Fix boot-time Embedded Controller GPE storm caused by incorrect
     resource assignment after ACPI Bus Check Notification (Mika
     Westerberg)

   - Protect pci_reassign_bridge_resources() against concurrent
     addition/removal (Benjamin Herrenschmidt)

   - Fix bridge dma_ranges resource list cleanup (Rob Herring)

   - Add "pci=hpmmiosize" and "pci=hpmmioprefsize" parameters to control
     the MMIO and prefetchable MMIO window sizes of hotplug bridges
     independently (Nicholas Johnson)

   - Fix MMIO/MMIO_PREF window assignment that assigned more space than
     desired (Nicholas Johnson)

   - Only enforce bus numbers from bridge EA if the bridge has EA
     devices downstream (Subbaraya Sundeep)

   - Consolidate DT "dma-ranges" parsing and convert all host drivers to
     use shared parsing (Rob Herring)

  Error reporting:

   - Restore AER capability after resume (Mayurkumar Patel)

   - Add PoisonTLPBlocked AER counter (Rajat Jain)

   - Use for_each_set_bit() to simplify AER code (Andy Shevchenko)

   - Fix AER kernel-doc (Andy Shevchenko)

   - Add "pcie_ports=dpc-native" parameter to allow native use of DPC
     even if platform didn't grant control over AER (Olof Johansson)

  Hotplug:

   - Avoid returning prematurely from sysfs requests to enable or
     disable a PCIe hotplug slot (Lukas Wunner)

   - Don't disable interrupts twice when suspending hotplug ports (Mika
     Westerberg)

   - Fix deadlocks when PCIe ports are hot-removed while suspended (Mika
     Westerberg)

  Power management:

   - Remove unnecessary ASPM locking (Bjorn Helgaas)

   - Add support for disabling L1 PM Substates (Heiner Kallweit)

   - Allow re-enabling Clock PM after it has been disabled (Heiner
     Kallweit)

   - Add sysfs attributes for controlling ASPM link states (Heiner
     Kallweit)

   - Remove CONFIG_PCIEASPM_DEBUG, including "link_state" and "clk_ctl"
     sysfs files (Heiner Kallweit)

   - Avoid AMD FCH XHCI USB PME# from D0 defect that prevents wakeup on
     USB 2.0 or 1.1 connect events (Kai-Heng Feng)

   - Move power state check out of pci_msi_supported() (Bjorn Helgaas)

   - Fix incorrect MSI-X masking on resume and revert related nvme quirk
     for Kingston NVME SSD running FW E8FK11.T (Jian-Hong Pan)

   - Always return devices to D0 when thawing to fix hibernation with
     drivers like mlx4 that used legacy power management (previously we
     only did it for drivers with new power management ops) (Dexuan Cui)

   - Clear PCIe PME Status even for legacy power management (Bjorn
     Helgaas)

   - Fix PCI PM documentation errors (Bjorn Helgaas)

   - Use dev_printk() for more power management messages (Bjorn Helgaas)

   - Apply D2 delay as milliseconds, not microseconds (Bjorn Helgaas)

   - Convert xen-platform from legacy to generic power management (Bjorn
     Helgaas)

   - Removed unused .resume_early() and .suspend_late() legacy power
     management hooks (Bjorn Helgaas)

   - Rearrange power management code for clarity (Rafael J. Wysocki)

   - Decode power states more clearly ("4" or "D4" really refers to
     "D3cold") (Bjorn Helgaas)

   - Notice when reading PM Control register returns an error (~0)
     instead of interpreting it as being in D3hot (Bjorn Helgaas)

937d6eefc7 Here's the main documentation changes for 5.5: 
- Various kerneldoc script enhancements.
 
  - More RST conversions; those are slowing down as we run out of things to
    convert, but we're a ways from done still.
 
  - Dan's "maintainer profile entry" work landed at last.  Now we just need
    to get maintainers to fill in the profiles...
 
  - A reworking of the parallel build setup to work better with a variety of
    systems (and to not take over huge systems entirely in particular).
 
  - The MAINTAINERS file is now converted to RST during the build.
    Hopefully nobody ever tries to print this thing, or they will need to
    load a lot of paper.
 
  - A script and documentation making it easy for maintainers to add Link:
    tags at commit time.
 
 Also included is the removal of a bunch of spurious CR characters.

99a0d9f5e8 This is the bulk of GPIO changes for the v5.5 kernel cycle 
Core changes:
 
 - Expose pull up/down flags for the GPIO character device to
   userspace. After clear input from the RaspberryPi and Beagle
   communities, it has been established that prototyping,
   industrial automation and make communities strongly need
   this feature, and as we want people to use the character
   device, we have implemented the simple pull up/down
   interface for GPIO lines. This means we can specify that
   a (chip-specific) pull up/down resistor can be enabled,
   but does not offer fine-grained control such as cases
   where the resistance of the same pull resistor can be
   controlled (yet).
 
 - Introduce devm_fwnode_gpiod_get_index() and start to phase out
   the old symbol devm_fwnode_get_index_gpiod_from_child().
 
 - A bit of documentation clean-up work.
 
 - Introduce a define for GPIO line directions and deploy it
   in all GPIO drivers in the drivers/gpio directory.
 
 - Add a special callback to populate pin ranges when
   cooperating with the pin control subsystem and registering
   ranges as part of adding a gpiolib driver and a
   gpio_irq_chip driver at the same time. This is also
   deployed in the Intel Merrifield driver.
 
 New drivers:
 
 - RDA Micro GPIO controller.
 
 - XGS-iproc GPIO driver.
 
 Driver improvements:
 
 - Wake event and debounce support on the Tegra 186 driver.
 
 - Finalize the Aspeed SGPIO driver.
 
 - MPC8xxx uses a normal IRQ handler rather than a chained
   handler.

ddebe839c6 This merge window we have one small clk provider API in the core framework and 
then a bunch of driver updates and a handful of new drivers. In terms of
 diffstat the Qualcomm and Amlogic drivers are high up there because of all the
 clk data introcued by new drivers. The Nvidia Tegra driver had a lot of work
 done this cycle too to support suspend/resume and memory controllers. And the
 OMAP clk driver got proper clk and reset handling in place.
 
 Rounding out the patches are various updates to remove unused data, mark things
 static, correct incorrect data in drivers, etc. All the little things that
 improve drivers and maintain code health. I will point out that there's a patch
 in here for the GPIO clk driver, that almost nobody uses, which changes
 behavior and causes clk_set_rate() to try to change the GPIO gate clk's parent.
 Other than that things are fairly well SoC specific here.
 
 Core:
  - Add a clk provider API to get current parent index
  - Plug a memory leak in clk_unregister() path
 
 New Drivers:
  - CGU in Ingenix X1000
  - Bitmain BM1880 clks
  - Qualcomm MSM8998 GPU clk controllers
  - Qualcomm SC7180 GCC and RPMH clk controllers
  - Qualcomm QCS404 Q6SSTOP clk controllers
  - Add support for the Renesas R-Car M3-W+ (r8a77961) SoC
  - Add support for the Renesas RZ/G2N (r8a774b1) SoC
  - Add Tegra20/30 External Memory Clock (EMC) support
 
 Updates:
  - Make gpio gate clks propagate rate setting up to parent
  - Prepare Armada 3700 for suspend to RAM by moving PCIe suspend/resume priority
  - Drop unused variables, enums, etc. in various clk drivers
  - Convert various drivers to use devm_platform_ioremap_resource()
  - Use struct_size() some more in various clk drivers
  - Improve Rockchip px30 clk tree
  - Add suspend/resume support to Tegra210 clk driver
  - Reimplement SOR clks on earlier Tegra SoCs, helping HDMI and DP
  - Allwinner DT exports and H6 clk tree fixes
  - Proper clk and reset handling for OMAP SoCs
  - Revamped TI divider clk to clamp max divider
  - Make 1443X/1416X PLL clock structure common for reusing among i.MX8 SoCs
  - Drop IMX7ULP_CLK_MIPI_PLL clock, it shouldn't be used
  - Add VIDEO2_PLL clock for imx8mq
  - Add missing gate clock for pll1/2 fixed dividers on i.MX8 SoCs
  - Add sm1 support in the Amlogic audio clock controller
  - Switch some clocks on R-Car Gen2/3 to .determine_rate()
  - Remove Renesas R-Car Gen2 legacy DT clock support
  - Improve arithmetic divisions on Renesas R-Car Gen2 and Gen3
  - Improve Renesas R-Car Gen3 SD clock handling
  - Add rate table for Samsung exynos542x GPU and VPLL clks
  - Fix potential CPU performance degradation after system suspend/resume cycle
    on exynos542x SoCs

dc5fa46568 This is the bulk of pin control changes for the v5.5 kernel 
series:
 
 Core changes:
 
 - Avoid taking direct references to device tree-supplied
   device names: these may changed at runtime under certain
   circumstances to kstrdup them.
 
 GPIO related:
 
 - Work is ongoing to move to passing the irqchip along as a
   templated struct gpio_irq_chip when adding a standard
   gpiolib-based irqchip to a GPIO controller, a few patches
   in this cycle switches a few pin control drivers over to
   using this method.
 
 New hardware support:
 
 - Intel Lightning Mountain SoC pin controller and GPIO
   support, a first Intel platform to use device tree rather
   than ACPI to configure the system. News reports says that
   this SoC is a network processor.
 
 - Qualcomm MSM8976 and MSM8956
 
 - Qualcomm PMIC GPIO now also supports PM6150 and PM6150L
 
 - Qualcomm SPMI MPP and SPMI GPIO for PM8950 and PMI8950
 
 - Rockchip RK3308
 
 - Renesas R8A77961
 
 - Allwinner Meson-A1
 
 Driver improvements:
 
 - get_multiple and set_multiple support for the AT91-PIO4 driver.
 
 - Convert Qualcomm SSBI GPIO to use the hierarchical IRQ helpers
   in the GPIOlib irqchip.

 "This is the bulk of pin control changes for v5.5.

  It is pretty much business as usual, the most interesting thing I
  think is the pin controller for a new Intel chip called Lightning
  Mountain, which is according to news reports some kind of embedded
  network processor and what is surprising about it is that Intel have
  decided to use device tree to describe the system rather than ACPI
  that they have traditionally favored.

  Core changes:

   - Avoid taking direct references to device tree-supplied device
     names: these may changed at runtime under certain circumstances to

     struct gpio_irq_chip when adding a standard gpiolib-based irqchip
     to a GPIO controller, a few patches in this cycle switches a few
     pin control drivers over to using this method.

  New hardware support:

   - Intel Lightning Mountain SoC pin controller and GPIO support, a
     first Intel platform to use device tree rather than ACPI to
     configure the system. News reports says that this SoC is a network
     processor.

   - Qualcomm MSM8976 and MSM8956

   - Qualcomm PMIC GPIO now also supports PM6150 and PM6150L

   - Qualcomm SPMI MPP and SPMI GPIO for PM8950 and PMI8950

   - Rockchip RK3308

   - Renesas R8A77961

   - Allwinner Meson-A1

  Driver improvements:

   - get_multiple and set_multiple support for the AT91-PIO4 driver.

   - Convert Qualcomm SSBI GPIO to use the hierarchical IRQ helpers in
     the GPIOlib irqchip"

3f1b210a7f sound updates for 5.5-rc1 
There have been some significant changes in the core side, both for
 ALSA and ASoC, while lots of development have been seen in SOF, as
 well as many small fixes/improvements for ASoC codecs and platforms.
 Below is a highlight in this cycle:
 
 Core:
 - The unification of PCM vmalloc buffer allocation helpers into the
   standard API
 - Clean up of the default PCM mmap handling for vmalloc & SG-buffer
 - Fix potential races at ALSA timer open
 - A few new PCM API extensions; just preliminary core changes, the
   actual changes in drivers will be merged in 5.6
 - Continued ASoC componentization works; now almost everything is a
   common ASoC component object.  A lot of refactoring and
   simplification have been done along with it.
 
 ASoC:
 - Many fixes to the Sound Open Firmware (SOF) code
 - Wake on voice support for Chromebooks
 - SPI support and trigger word detection for RT5677
 - New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
   with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770
 
 HD-audio:
 - Improved Intel DSP configuration / probe code for SOF
 - Plumbing the legacy HD-audio driver with Intel SOF HDMI
 - DP-MST support for Nvidia HDMI codecs
 - Realtek quirks cleanups and new additions as usual
 
 Others:
 - Lots of refactoring and cleanups for FireWire; period-size sharing,
   h/w IRQ interval configuration, clock recovery improvements, etc
 - USB-audio: Scarlett mixer quirks
 - Cleanups of PCM calls in various drivers (including media and USB)
   to adapt the core API changes

Merge tag 'pm-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
 "These include cpuidle changes to use nanoseconds (instead of
  microseconds) as the unit of time and to simplify checks for disabled
  idle states in the idle loop, some cpuidle fixes and governor updates,
  assorted cpufreq updates (driver updates mostly and a few core fixes
  and cleanups), devfreq updates (dominated by the tegra30 driver
  changes), new CPU IDs for the RAPL power capping driver, relatively
  minor updates of the generic power domains (genpd) and operation
  performance points (OPP) frameworks, and assorted fixes and cleanups.

  There are also two maintainer information updates: Chanwoo Choi will
  be maintaining the devfreq subsystem going forward and Todd Brandt is
  going to maintain the pm-graph utility (created by him).

  Specifics:

   - Use nanoseconds (instead of microseconds) as the unit of time in
     the cpuidle core and simplify checks for disabled idle states in
     the idle loop (Rafael Wysocki)

   - Fix and clean up the teo cpuidle governor (Rafael Wysocki)

   - Fix the cpuidle registration error code path (Zhenzhong Duan)

   - Avoid excessive vmexits in the ACPI cpuidle driver (Yin Fengwei)

   - Extend the idle injection infrastructure to be able to measure the
     requested duration in nanoseconds and to allow an exit latency
     limit for idle states to be specified (Daniel Lezcano)

   - Fix cpufreq driver registration and clarify a comment in the
     cpufreq core (Viresh Kumar)

   - Add NULL checks to the show() and store() methods of sysfs
     attributes exposed by cpufreq (Kai Shen)

   - Update cpufreq drivers:
      * Fix for a plain int as pointer warning from sparse in
        intel_pstate (Jamal Shareef)
      * Fix for a hardcoded number of CPUs and stack bloat in the
        powernv driver (John Hubbard)
      * Updates to the ti-cpufreq driver and DT files to support new
        platforms and migrate bindings from opp-v1 to opp-v2 (Adam Ford,
        H. Nikolaus Schaller)
      * Merging of the arm_big_little and vexpress-spc drivers and
        related cleanup (Sudeep Holla)
      * Fix for imx's default speed grade value (Anson Huang)
      * Minor cleanup of the s3c64xx driver (Nathan Chancellor)
      * CPU speed bin detection fix for sun50i (Ondrej Jirman)

   - Appoint Chanwoo Choi as the new devfreq maintainer.

   - Update the devfreq core:
      * Check NULL governor in available_governors_show sysfs to prevent
        showing wrong governor information and fix a race condition
        between devfreq_update_status() and trans_stat_show() (Leonard
        Crestez)
      * Add new 'interrupt-driven' flag for devfreq governors to allow
        interrupt-driven governors to prevent the devfreq core from
        polling devices for status (Dmitry Osipenko)
      * Improve an error message in devfreq_add_device() (Matthias
        Kaehlcke)

   - Update devfreq drivers:
      * tegra30 driver fixes and cleanups (Dmitry Osipenko)
      * Removal of unused property from dt-binding documentation for the
        exynos-bus driver (Kamil Konieczny)
      * exynos-ppmu cleanup and DT bindings update (Lukasz Luba, Marek
        Szyprowski)

   - Add new CPU IDs for CometLake Mobile and Desktop to the Intel RAPL
     power capping driver (Zhang Rui)

   - Allow device initialization in the generic power domains (genpd)
     framework to be more straightforward and clean it up (Ulf Hansson)

   - Add support for adjusting OPP voltages at run time to the OPP
     framework (Stephen Boyd)

   - Avoid freeing memory that has never been allocated in the
     hibernation core (Andy Whitcroft)

   - Clean up function headers in a header file and coding style in the
     wakeup IRQs handling code (Ulf Hansson, Xiaofei Tan)

   - Clean up the SmartReflex adaptive voltage scaling (AVS) driver for
     ARM (Ben Dooks, Geert Uytterhoeven)

   - Wrap power management documentation to fit in 80 columns (Bjorn
     Helgaas)

   - Add pm-graph utility entry to MAINTAINERS (Todd Brandt)

   - Update the cpupower utility:
      * Fix the handling of set and info subcommands (Abhishek Goel)
      * Fix build warnings (Nathan Chancellor)
      * Improve mperf_monitor handling (Janakarajan Natarajan)"
