Linus Torvalds e6874fc294 Staging/IIO driver patches for 5.4-rc1
Here is the big staging/iio driver update for 5.4-rc1.
 
 Lots of churn here, with a few driver/filesystems moving out of staging
 finally:
 	- erofs moved out of staging
 	- greybus core code moved out of staging
 
 Along with that, a new filesytem has been added:
 	- extfat
 to provide support for those devices requiring that filesystem (i.e.
 transfer devices to/from windows systems or printers.)
 
 Other than that, there a number of new IIO drivers, and lots and lots
 and lots of staging driver cleanups and minor fixes as people continue
 to dig into those for easy changes.
 
 All of these have been in linux-next for a while with no reported
 issues.

Linus Torvalds e444d51b14 TTY/Serial driver changes for 5.4-rc1
Even in this age, people are still making new serial port silicon,
 why...
 
 Anyway, here's the TTY and Serial driver update for 5.4-rc1.  Lots of
 changes in here for a number of embedded serial port devices that are
 being worked on because people really like to see those console logs...
 
 Other than that, nothing major here, no core tty changes that anyone
 should care about.
 
 All of these have been in linux-next for a while with no reported

Linus Torvalds c6b48dad92 USB changes for 5.4-rc1
Here is the big set of USB patches for 5.4-rc1.
 
 Two major chunks of code are moving out of the tree and into the staging
 directory, uwb and wusb (wireless USB support), because there are no
 devices that actually use this protocol anymore, and what we have today
 probably doesn't work at all given that the maintainers left many many
 years ago.  So move it to staging where it will be removed in a few
 releases if no one screams.
 
 Other than that, lots of little things.  The usual gadget and xhci and
 usb serial driver updates, along with a bunch of sysfs file cleanups due
 to the driver core changes to support that.  Nothing really major, just
 constant forward progress.
 
 All of these have been in linux-next for a while with no reported

Linus Torvalds 1f7d290a72 Driver core patches for 5.4-rc1
Here is the big driver core update for 5.4-rc1.
 
 There was a bit of a churn in here, with a number of core and OF
 platform patches being added to the tree, and then after much discussion
 and review and a day-long in-person meeting, they were decided to be
 reverted and a new set of patches is currently being reviewed on the
 mailing list.
 
 Other than that churn, there are two "persistent" branches in here that
 other trees will be pulling in as well during the merge window.  One
 branch to add support for drivers to have the driver core automatically
 add sysfs attribute files when a driver is bound to a device so that the
 driver doesn't have to manually do it (and then clean it up, as it
 always gets it wrong).
 
 There's another branch in here for generic lookup helpers for the driver
 core that lots of busses are starting to use.  That's the majority of
 the non-driver-core changes in this patch series.
 
 There's also some on-going debugfs file creation cleanup that has been
 slowly happening over the past few releases, with the goal to hopefully
 get that done sometime next year.
 
 All of these have been in linux-next for a while now with no reported
 issues.

  shared it.

  Also note that that common branch introduced an i2c bug due to a bad

Linus Torvalds 77dcfe2b9e Power management updates for 5.4-rc1
- Rework the main suspend-to-idle control flow to avoid repeating
    "noirq" device resume and suspend operations in case of spurious
    wakeups from the ACPI EC and decouple the ACPI EC wakeups support
    from the LPS0 _DSM support (Rafael Wysocki).
 
  - Extend the wakeup sources framework to expose wakeup sources as
    device objects in sysfs (Tri Vo, Stephen Boyd).
 
  - Expose system suspend statistics in sysfs (Kalesh Singh).
 
  - Introduce a new haltpoll cpuidle driver and a new matching
    governor for virtualized guests wanting to do guest-side polling
    in the idle loop (Marcelo Tosatti, Joao Martins, Wanpeng Li,
    Stephen Rothwell).
 
  - Fix the menu and teo cpuidle governors to allow the scheduler tick
    to be stopped if PM QoS is used to limit the CPU idle state exit
    latency in some cases (Rafael Wysocki).
 
  - Increase the resolution of the play_idle() argument to microseconds
    for more fine-grained injection of CPU idle cycles (Daniel Lezcano).
 
  - Switch over some users of cpuidle notifiers to the new QoS-based
    frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
    policy notifier events (Viresh Kumar).
 
  - Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).
 
  - Add support for MT8183 and MT8516 to the mediatek cpufreq driver
    (Andrew-sh.Cheng, Fabien Parent).
 
  - Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
    Huang).
 
  - Add qcs404 to cpufreq-dt-platdev blacklist (Jorge Ramirez-Ortiz).

Pull power management updates from Rafael Wysocki:
 "These include a rework of the main suspend-to-idle code flow (related
  to the handling of spurious wakeups), a switch over of several users
  of cpufreq notifiers to QoS-based limits, a new devfreq driver for
  Tegra20, a new cpuidle driver and governor for virtualized guests, an
  extension of the wakeup sources framework to expose wakeup sources as
  device objects in sysfs, and more.

  Specifics:

   - Rework the main suspend-to-idle control flow to avoid repeating
     "noirq" device resume and suspend operations in case of spurious
     wakeups from the ACPI EC and decouple the ACPI EC wakeups support
     from the LPS0 _DSM support (Rafael Wysocki).

   - Extend the wakeup sources framework to expose wakeup sources as
     device objects in sysfs (Tri Vo, Stephen Boyd).

   - Expose system suspend statistics in sysfs (Kalesh Singh).

   - Introduce a new haltpoll cpuidle driver and a new matching governor
     for virtualized guests wanting to do guest-side polling in the idle
     loop (Marcelo Tosatti, Joao Martins, Wanpeng Li, Stephen Rothwell).

   - Fix the menu and teo cpuidle governors to allow the scheduler tick
     to be stopped if PM QoS is used to limit the CPU idle state exit
     latency in some cases (Rafael Wysocki).

   - Increase the resolution of the play_idle() argument to microseconds
     for more fine-grained injection of CPU idle cycles (Daniel
     Lezcano).

   - Switch over some users of cpuidle notifiers to the new QoS-based
     frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
     policy notifier events (Viresh Kumar).

   - Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).

   - Add support for MT8183 and MT8516 to the mediatek cpufreq driver
     (Andrew-sh.Cheng, Fabien Parent).

   - Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
     Huang).

   - Add qcs404 to cpufreq-dt-platdev blacklist (Jorge Ramirez-Ortiz).

   - Update the qcom cpufreq driver (among other things, to make it
     easier to extend and to use kryo cpufreq for other nvmem-based
     SoCs) and add qcs404 support to it (Niklas Cassel, Douglas

   - Fix assorted issues and make assorted minor improvements in the
     cpufreq code (Colin Ian King, Douglas RAILLARD, Florian Fainelli,

Merge tag 'leds-for-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds

Pull LED updates from Jacek Anaszewski:
 "In this cycle we've finally managed to contribute the patch set
  sorting out LED naming issues. Besides that there are many changes
  scattered among various LED class drivers and triggers.

  LED naming related improvements:

   - add new 'function' and 'color' fwnode properties and deprecate
     'label' property which has been frequently abused for conveying
     vendor specific names that have been available in sysfs anyway

   - introduce a set of standard LED_FUNCTION* definitions

   - introduce a set of standard LED_COLOR_ID* definitions

   - add a new {devm_}led_classdev_register_ext() API with the
     capability of automatic LED name composition basing on the
     properties available in the passed fwnode; the function is
     backwards compatible in a sense that it uses 'label' data, if
     present in the fwnode, for creating LED name

   - add tools/leds/get_led_device_info.sh script for retrieving LED
     vendor, product and bus names, if applicable; it also performs
     basic validation of an LED name

   - update following drivers and their DT bindings to use the new LED
     registration API:

        - leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
          leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt

  Other LED class improvements:

   - replace {devm_}led_classdev_register() macros with inlines

   - allow to call led_classdev_unregister() unconditionally

   - switch to use fwnode instead of be stuck with OF one

  LED triggers improvements:

   - led-triggers:
        - fix dereferencing of null pointer
        - fix a memory leak bug

   - ledtrig-gpio:
        - GPIO 0 is valid

  Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
  more complete driver exists, based on a generic driver for the AMD
  SOCs gpio-controller, supporting LEDs as well other devices:

   - drop profile field from priv data

   - drop iosize field from priv data

   - drop enum_apu_led_platform_types

   - drop superseeded apu2/3 led support

   - add pr_fmt prefix for better log output

   - fix error message on probing failure

  Other misc fixes and improvements to existing LED class drivers:

   - leds-ns2, leds-max77650:
        - add of_node_put() before return

   - leds-pwm, leds-is31fl32xx:
        - use struct_size() helper

   - leds-lm3697, leds-lm36274, leds-lm3532:
        - switch to use fwnode_property_count_uXX()

   - leds-lm3532:
        - fix brightness control for i2c mode
        - change the define for the fs current register
        - fixes for the driver for stability
        - add full scale current configuration
        - dt: Add property for full scale current.
        - avoid potentially unpaired regulator calls
        - move static keyword to the front of declarations
        - fix optional led-max-microamp prop error handling

   - leds-max77650:
        - add of_node_put() before return
        - add MODULE_ALIAS()
        - Switch to fwnode property API

   - leds-as3645a:
        - fix misuse of strlcpy

   - leds-netxbig:
        - add of_node_put() in netxbig_leds_get_of_pdata()
        - remove legacy board-file support

   - leds-is31fl319x:
        - simplify getting the adapter of a client

   - leds-ti-lmu-common:
        - fix coccinelle issue
        - move static keyword to the front of declaration

   - leds-syscon:
        - use resource managed variant of device register

   - leds-ktd2692:
        - fix a typo in the name of a constant

   - leds-lp5562:
        - allow firmware files up to the maximum length

   - leds-an30259a:
        - fix typo

   - leds-pca953x:
        - include the right header"

Linus Torvalds 6ab8ad3160 sound updates for 5.4
As shown in diffstat and logs, it was again a busy development
 cycle at this time, too.  The most significant changes are still
 on-going refactoring / modernization works for ASoC core and
 drivers, but there are lots of other changes as well.  Here we go,
 some highlights below:
 
 ASoC:
 - Quite lots of cleanup / refactoring of ASoC core and APIs;
   most of them are systematic, but also including cleanups and
   modernization
 
 - A bulk of updates for some ASoC platforms, Freescale, sunxi and
   Intel SST/SOF
 
 - Initial support for Sound Open Firmware on i.MX8
 
 - Removal of deprecated w90x900 and nuc900 drivers
 
 - New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
   7ULP and 8MQ, Meson G12A and NXP UDA1334
 
 USB-audio:
 - More validations of descriptor units for hardening against bugs
   reported by fuzzers
 
 - PCM device assignment workaround for a past call-order change
 
 - Scarlett Gen2 mixer interface, a few more more quirks
 
 HD-audio:
 - Support for audio component with AMD/ATI and Nvidia HDMI codecs
 
 - Clean up HD-audio core and remove indirect access ops for Intel SOF
 
 - DMIC detection at probe; it would make systems automatically falling
   back to SST/SOF driver on devices that need DMIC handling.
   Needs a new Kconfig to set, and beware that it's still new and a bit
   experimental
 
 FireWire:
 - Lots of code refactoring and cleanups

Merge tag 'sound-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "As shown in diffstat and logs, it was again a busy development cycle
  at this time, too. The most significant changes are still on-going
  refactoring / modernization works for ASoC core and drivers, but there
  are lots of other changes as well. Here we go, some highlights below:

  ASoC:

   - Quite a lot of cleanup / refactoring of ASoC core and APIs; most of
     them are systematic, but also including cleanups and modernization

   - A bulk of updates for some ASoC platforms, Freescale, sunxi and
     Intel SST/SOF

   - Initial support for Sound Open Firmware on i.MX8

   - Removal of deprecated w90x900 and nuc900 drivers

   - New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
     7ULP and 8MQ, Meson G12A and NXP UDA1334

  USB-audio:

   - More validations of descriptor units for hardening against bugs
     reported by fuzzers

   - PCM device assignment workaround for a past call-order change

   - Scarlett Gen2 mixer interface, a few more more quirks

  HD-audio:

   - Support for audio component with AMD/ATI and Nvidia HDMI codecs

   - Clean up HD-audio core and remove indirect access ops for Intel SOF

   - DMIC detection at probe; it would make systems automatically
     falling back to SST/SOF driver on devices that need DMIC handling.
     Needs a new Kconfig to set, and beware that it's still new and a
     bit experimental

  FireWire:

   - Lots of code refactoring and cleanups"

Linus Torvalds 7c672abc12 It's a somewhat calmer cycle for docs this time, as the churn of the mass
RST conversion is happily mostly behind us.
 
  - A new document on reproducible builds.
 
  - We finally got around to zapping the documentation for hardware support
    that was removed in 2004; one doesn't want to rush these things.
 
  - The usual assortment of fixes, typo corrections, etc.
 
 You'll still find a handful of annoying conflicts against other trees,
 mostly tied to the last RST conversions; resolutions are straightforward
 and the linux-next ones are good.

Pull core timer updates from Thomas Gleixner:
 "Timers and timekeeping updates:

   - A large overhaul of the posix CPU timer code which is a preparation
     for moving the CPU timer expiry out into task work so it can be
     properly accounted on the task/process.

     An update to the bogus permission checks will come later during the
     merge window as feedback was not complete before heading of for
     travel.

   - Switch the timerqueue code to use cached rbtrees and get rid of the
     homebrewn caching of the leftmost node.

   - Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a
     single function

   - Implement the separation of hrtimers to be forced to expire in hard
     interrupt context even when PREEMPT_RT is enabled and mark the
     affected timers accordingly.

   - Implement a mechanism for hrtimers and the timer wheel to protect
     RT against priority inversion and live lock issues when a (hr)timer
     which should be canceled is currently executing the callback.
     Instead of infinitely spinning, the task which tries to cancel the
     timer blocks on a per cpu base expiry lock which is held and
     released by the (hr)timer expiry code.

   - Enable the Hyper-V TSC page based sched_clock for Hyper-V guests
     resulting in faster access to timekeeping functions.

   - Updates to various clocksource/clockevent drivers and their device
     tree bindings.

   - The usual small improvements all over the place"

Pull scheduler updates from Ingo Molnar:

 - MAINTAINERS: Add Mark Rutland as perf submaintainer, Juri Lelli and
   Vincent Guittot as scheduler submaintainers. Add Dietmar Eggemann,
   Steven Rostedt, Ben Segall and Mel Gorman as scheduler reviewers.

   As perf and the scheduler is getting bigger and more complex,
   document the status quo of current responsibilities and interests,
   and spread the review pain^H^H^H^H fun via an increase in the Cc:
   linecount generated by scripts/get_maintainer.pl. :-)

 - Add another series of patches that brings the -rt (PREEMPT_RT) tree
   closer to mainline: split the monolithic CONFIG_PREEMPT dependencies
   into a new CONFIG_PREEMPTION category that will allow the eventual
   introduction of CONFIG_PREEMPT_RT. Still a few more hundred patches
   to go though.

 - Extend the CPU cgroup controller with uclamp.min and uclamp.max to
   allow the finer shaping of CPU bandwidth usage.

 - Micro-optimize energy-aware wake-ups from O(CPUS^2) to O(CPUS).

 - Improve the behavior of high CPU count, high thread count
   applications running under cpu.cfs_quota_us constraints.

 - Improve balancing with SCHED_IDLE (SCHED_BATCH) tasks present.

 - Improve CPU isolation housekeeping CPU allocation NUMA locality.

 - Fix deadline scheduler bandwidth calculations and logic when cpusets
   rebuilds the topology, or when it gets deadline-throttled while it's
   being offlined.

 - Convert the cpuset_mutex to percpu_rwsem, to allow it to be used from
   setscheduler() system calls without creating global serialization.
   Add new synchronization between cpuset topology-changing events and
   the deadline acceptance tests in setscheduler(), which were broken
   before.

Linus Torvalds cef7298262 ARM: DT updates for v5.4
This is another huge branch with close to 450 changessets related to
 devicetree files, roughly half of this for 32-bit and 64-bit respectively.
 There are lots of cleanups and additional hardware support for platforms
 we already support based on SoCs from Renesas, ST-Microelectronics,
 Intel/Altera, Rockchips, Allwinner, Broadcom and other manufacturers.
 
 A total of 6 new SoCs and 37 new boards gets added this time, one more
 SoC will come in a follow-up branch. Most of the new boards are for
 64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7.
 
 Going more into details for SoC platforms with new hardware support:
 
 The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone platform,
 usually paired with an external 5G modem. So far we only support the
 Qualcomm SM8150 MTP reference platform, but no actual products.
 
 For the slightly older Qualcomm platforms, support for several interesting
 products is getting added: Three laptops based on Snapdragon 835/MSM8998
 (Asus NovaGo, HP Envy X2 and Lenovo Miix 630), one laptop based on
 Snapdragon 850/sdm850 (Lenovo Yoga C630) and several phones based on
 the older Snapdragon 410/MSM8916 (Samsung A3 and A5, Longcheer L8150
 aka Android One 2nd gen "seed" aka Wileyfox Swift).
 
 Mediatek MT7629 is a new wireless network router chip, similar to
 the older MT7623. It gets added together with the reference board
 implementation.
 
 Allwinner V3 is a repackaged version of the existing low-end V3s chip,
 and is used in the tiny Lichee Pi Zero plus, also added here.  There is
 also a new TV set-top box based on Allwinner H6, the Tanix TX6, and the
 eMMC variant of the Olimex A64-Olinuxino development board.
 
 NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC family,
 similar to the i.MX8M Mini. As usual, there is a large number of new
 boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML, SolidRun Hummingboard
 Pulse baseboard and System-on-Module, Boundary Devices i.MX8MQ Nitrogen8M,
 and TechNexion PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit,
 we get the Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC
 phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight
 Innovations i.MX7 RMU2 board.
 
 In a different NXP product line, the Layerscape LS1046A "Freeway"
 reference board gets added.
 
 Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from their
 set-top-box line and smart speaker with newer CPU and GPU cores compared
 to their predecessors. Both are now also supported by the Khadas VIM3
 development board series, and the dts files for that get reorganized a
 bit to better deal with all variants.  Another board based on SM1 that
 gets added is the SEI Robotics SEI610.
 
 There are a handful of new x86 and Power9 server boards using Aspeed BMC
 chips that are gaining support for running Linux on the BMC through the
 OpenBMC project: Facebook Minipack/Wedge100/Wedge40, Lenovo Hr855xg2,
 and Mihawk. Notably these are still new machines using SoCs based on
 the ARM9 and ARM11 CPU cores, as support for the new Cortex-A7 based
 AST2600 is still ramping up.
 
 There are three new end-user products using 32-bit Rockchips SoCs:
 Mecer Xtreme Mini S6 is an Android "mini PC" box based on the low-end
 RK3229 chip, while the two AOpen products Chromebox Mini (Fievel) and
 Chromebase Mini (Tiger) run ChromeOS and are meant for commercial settings
 (digital signage, PoS, ...).
 
 One more single-board computer based on the popular 64-bit RK3399 is
 added: the Leez RK3399 P710.

 - The Turris Mox router has a new "moxtet" bus driver
   for its on-board pluggable extension bus. The
   same platform also gains a firmware driver.
 
 - The Samsung Exynos family gains a new Chipid driver
   exporting using the soc device sysfs interface
 
 - A similar socinfo driver for Qualcomm Snapdragon
   chips.
 
 - A firmware driver for the NXP i.MX DSP IPC protocol
   using shared memory and a mailbox
 
 Other changes:
 
 - The i.MX reset controller driver now supports the
   NXP i.MX8MM chip
 
 - Amlogic SoC specific drivers gain support for
   the S905X3 and A311D chips
 
 - A rework of the TI Davinci framebuffer driver to
   allow important cleanups in the platform code
 
 - A couple of device drivers for removed ARM SoC
   platforms are removed. Most of the removals were
   picked up by other maintainers, this contains
   whatever was left.

Linus Torvalds 2b97c39514 ARM: SoC platform updates for v5.4
The main change this time around is a cleanup of some of the oldest
 platforms based on the XScale and ARM9 CPU cores, which are between 10
 and 20 years old.
 
 The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel
 IOP33x/IOP13xx platforms are removed after we determined that nobody is
 using them any more.
 
 The TI Davinci and NXP LPC32xx platforms on the other hand are still in
 active use and are converted to the ARCH_MULTIPLATFORM build, meaning
 that we can compile a kernel that works on these along with most other
 ARMv5 platforms. Changes toward that goal are also merged for IOP32x,
 but additional work is needed to complete this. Patches for the
 remaining ARMv5 platforms have started but need more work and some
 testing.
 
 Support for the new ASpeed AST2600 gets added, this is based on the
 Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and
 ARMv6 chips in the same family.
 
 Other changes include a cleanup of the ST-Ericsson ux500 platform
 and the move of the TI Davinci platform to a new clocksource driver.

Pull arm64 updates from Will Deacon:
 "Although there isn't tonnes of code in terms of line count, there are
  a fair few headline features which I've noted both in the tag and also
  in the merge commits when I pulled everything together.

  The part I'm most pleased with is that we had 35 contributors this
  time around, which feels like a big jump from the usual small group of
  core arm64 arch developers. Hopefully they all enjoyed it so much that
  they'll continue to contribute, but we'll see.

  It's probably worth highlighting that we've pulled in a branch from
  the risc-v folks which moves our CPU topology code out to where it can
  be shared with others.

  Summary:

   - 52-bit virtual addressing in the kernel

   - New ABI to allow tagged user pointers to be dereferenced by
     syscalls

   - Early RNG seeding by the bootloader

   - Improve robustness of SMP boot

Linus Torvalds bbfe0d6b8b This is the bulk of changes in the GPIO subsystem for the
v5.4 kernel cycle.
 
 Core changes:
 
 - Support hierarchical GPIO irqchips. We now have three
   consumers that can use this: Intel IXP4xx, ThunderX and
   Qualcomm SPMI GPIO (in the pinctrl subsystem). The support
   code has been long in the making and hashed out so it should
   be easily adaptable for all hierarchical irqchip parents.
   The code only gets compiled in if hierarchical irqchip
   is used at the topmost irq controller at least, as the
   hierarchical irqchip requires strict hierarchy all the
   way up in the system.
 
 - Determine the need for a "valid_mask" for GPIO lines on the
   gpio_chip and conversely for the "valid_mask" for the GPIO
   interrupt chip interrupt lines by looking for a
   .init_valid_mask() callback in the main chip or GPIO interrupt
   chip respectively. Allocate it with bitmap_alloc().
 
 - Isolate the device tree/open firmware GPIO description code
   out in its own file properly.
 
 - Isolate the ACPI GPIO description code out in its own file
   properly.
 
 - Drop a whole lot of #ifdef:s in the main includes: it does
   not hurt to keep the include items around, and we get
   quicker and clearer compile failures if the appropriate
   kernel symbols are not selected for drivers.
 
 New/deleted drivers:
 
 - New driver for Aspeed SGPIO.
 
 - The KS8695 driver is deleted as the platform gets deleted
   from arch/arm in this kernel cycle.
 
 - The Cirrus Logic Madera driver now supports CS47L92 and
   CS47L15.
 
 - The Freescale MPC8xxx now supports LS1028A and LS1088A.
 
 Driver improvements:
 
 - We pass the GPIO irqchip intialization by directly filling
   in the struct instead of using set-up functions (the new
   way) for Intel MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed,
   ZX, VF610, TQMX86, MT7621, Zynq and EP93xx.
 
 Out-of-band changes:
 
 - Fix a GPIO header inclusion in Unicore - no response from
   maintainer.
 
 - Drop FMC subsystem from MAINTAINERS - was deleted in the
   GPIO tree last cycle so let's mop up the shards.

Linus Torvalds aa62325dc3 spi: Updates for v5.4
The big theme for this release has been performance, we've had a series
 of unrelated overhauls of a few drivers all with a big peformance
 component.  Otherwise it's been relatively quiet, highlights include:
 
  - A big overhaul of the spi-fsl-dspi driver improving the code quality,
    performance and stability from Vladimir Oltean.
  - A big performance enhancement for the bc2835 (Raspberry Pi) driver
    for unidirectional transfers from Lukas Wunner.
  - Improved performance on small transfers for the uniphier driver from
    Keiji Hayashibara.
  - Lots of coccinelle generated cleanups from Yue Haibing.
  - New device support for Freescale ls2080a and Nuvoton NPCM FIU.

Linus Torvalds c4d11ccb2b regulator: Updates for v5.4
A small update for the regualtor API for this cycle, some small fixes
 and a bunch of new devices but none of them very big.  The most stand
 out thing is the regulator-fixed-clock driver which is for regulators
 where the enable control is done by using a clock instead of a GPIO or
 register write, a novel hardware design that had not previously come up.
 
  - Added a keyword pattern for regulator_get_optional() since usage of
    that API generally needs extra review.
  - Operating mode and suspend state support for act8865.
  - New device support for Active Semiconductor ACT8600 chargers,
    Mediatek MT6358, Qualcomm SM8150, regulator-fixed-clock, and
    Synoptics SY20276, SY20278 and SY8824E.

Yan, Zheng 131d7eb4fa ceph: auto reconnect after blacklisted
Make client use osd reply and session message to infer if itself is
blacklisted. Client reconnect to cluster using new entity addr if it
is blacklisted. Auto reconnect is limited to once every 30 minutes.

Auto reconnect is disabled by default. It can be enabled/disabled by
recover_session=<no|clean> mount option. In 'clean' mode, client drops
any dirty data/metadata, invalidates page caches and invalidates all
writable file handles. After reconnect, file locks become stale because
MDS loses track of them. If an inode contains any stale file locks,
read/write on the indoe are not allowed until applications release all
stale file locks.

Joe Perches cbacb5ab0a docs: printk-formats: Stop encouraging use of unnecessary %h[xudi] and %hh[xudi]
Standard integer promotion is already done and %hx and %hhx is useless
so do not encourage the use of %hh[xudi] or %h[xudi].

As Linus said in:
https://lore.kernel.org/lkml/CAHk-=wgoxnmsj8GEVFJSvTwdnWm8wVJthefNk2n6+4TC=20e0Q@mail.gmail.com/

It's a pointless warning, making for more complex code, and
making people remember esoteric printf format details that have no
reason for existing.

The "h" and "hh" things should never be used. The only reason for them
being used if if you have an "int", but you want to print it out as a
"char" (and honestly, that is a really bad reason, you'd be better off
just using a proper cast to make the code more obvious).

So if what you have a "char" (or unsigned char) you should always just
print it out as an "int", knowing that the compiler already did the
proper type conversion.

Paul Walmsley 474efecb65 riscv: modify the Image header to improve compatibility with the ARM64 header
Part of the intention during the definition of the RISC-V kernel image
header was to lay the groundwork for a future merge with the ARM64
image header.  One error during my original review was not noticing
that the RISC-V header's "magic" field was at a different size and
position than the ARM64's "magic" field.  If the existing ARM64 Image
header parsing code were to attempt to parse an existing RISC-V kernel
image header format, it would see a magic number 0.  This is
undesirable, since it's our intention to align as closely as possible
with the ARM64 header format.  Another problem was that the original
"res3" field was not being initialized correctly to zero.

Address these issues by creating a 32-bit "magic2" field in the RISC-V
header which matches the ARM64 "magic" field.  RISC-V binaries will
store "RSC\x05" in this field.  The intention is that the use of the
existing 64-bit "magic" field in the RISC-V header will be deprecated
over time.  Increment the minor version number of the file format to
indicate this change, and update the documentation accordingly.  Fix
the assembler directives in head.S to ensure that reserved fields are
properly zero-initialized.

Nikos Tsironis 7431b7835f dm: add clone target
Add the dm-clone target, which allows cloning of arbitrary block
devices.

dm-clone produces a one-to-one copy of an existing, read-only source
device into a writable destination device: It presents a virtual block
device which makes all data appear immediately, and redirects reads and
writes accordingly.

The main use case of dm-clone is to clone a potentially remote,
high-latency, read-only, archival-type block device into a writable,
fast, primary-type device for fast, low-latency I/O. The cloned device
is visible/mountable immediately and the copy of the source device to
the destination device happens in the background, in parallel with user
I/O.

When the cloning completes, the dm-clone table can be removed altogether
and be replaced, e.g., by a linear table, mapping directly to the
destination device.

For further information and examples of how to use dm-clone, please read
Documentation/admin-guide/device-mapper/dm-clone.rst

Marc Zyngier 92f35b751c KVM: arm/arm64: vgic: Allow more than 256 vcpus for KVM_IRQ_LINE
While parts of the VGIC support a large number of vcpus (we
bravely allow up to 512), other parts are more limited.

One of these limits is visible in the KVM_IRQ_LINE ioctl, which
only allows 256 vcpus to be signalled when using the CPU or PPI
types. Unfortunately, we've cornered ourselves badly by allocating
all the bits in the irq field.

Since the irq_type subfield (8 bit wide) is currently only taking
the values 0, 1 and 2 (and we have been careful not to allow anything
else), let's reduce this field to only 4 bits, and allocate the
remaining 4 bits to a vcpu2_index, which acts as a multiplier:

  vcpu_id = 256 * vcpu2_index + vcpu_index

With that, and a new capability (KVM_CAP_ARM_IRQ_LINE_LAYOUT_2)
allowing this to be discovered, it becomes possible to inject
PPIs to up to 4096 vcpus. But please just don't.

Whilst we're there, add a clarification about the use of KVM_IRQ_LINE
on arm, which is not completely conditionned by KVM_CAP_IRQCHIP.

Daniel Borkmann says:

====================
The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Add the ability to use unaligned chunks in the AF_XDP umem. By
   relaxing where the chunks can be placed, it allows to use an
   arbitrary buffer size and place whenever there is a free
   address in the umem. Helps more seamless DPDK AF_XDP driver
   integration. Support for i40e, ixgbe and mlx5e, from Kevin and
   Maxim.

2) Addition of a wakeup flag for AF_XDP tx and fill rings so the
   application can wake up the kernel for rx/tx processing which
   avoids busy-spinning of the latter, useful when app and driver
   is located on the same core. Support for i40e, ixgbe and mlx5e,
   from Magnus and Maxim.

3) bpftool fixes for printf()-like functions so compiler can actually
   enforce checks, bpftool build system improvements for custom output
   directories, and addition of 'bpftool map freeze' command, from Quentin.

4) Support attaching/detaching XDP programs from 'bpftool net' command,
   from Daniel.

5) Automatic xskmap cleanup when AF_XDP socket is released, and several
   barrier/{read,write}_once fixes in AF_XDP code, from Björn.

6) Relicense of bpf_helpers.h/bpf_endian.h for future libbpf
   inclusion as well as libbpf versioning improvements, from Andrii.

7) Several new BPF kselftests for verifier precision tracking, from Alexei.

8) Several BPF kselftest fixes wrt endianess to run on s390x, from Ilya.

9) And more BPF kselftest improvements all over the place, from Stanislav.

10) Add simple BPF map op cache for nfp driver to batch dumps, from Jakub.

11) AF_XDP socket umem mapping improvements for 32bit archs, from Ivan.

Masahiro Yamada e27128db62 kbuild: rename KBUILD_ENABLE_EXTRA_GCC_CHECKS to KBUILD_EXTRA_WARN
KBUILD_ENABLE_EXTRA_GCC_CHECKS started as a switch to add extra warning
options for GCC, but now it is a historical misnomer since we use it
also for Clang, DTC, and even kernel-doc.

Rename it to more sensible, shorter KBUILD_EXTRA_WARN.

For the backward compatibility, KBUILD_ENABLE_EXTRA_GCC_CHECKS is still
supported (but not advertised in the documentation).

I also fixed up 'make help', and updated the documentation.

Adam Borowski 209c3aa7f0 Documentation: sysrq: don't recommend 'S' 'U' before 'B'
This advice is obsolete and slightly harmful for filesystems from this
millenium: any modern filesystem can handle unexpected crashes without
requiring fsck -- and on the other hand, trying to write to the disk when
the kernel is in a bad state risks introducing corruption.

For ext2, any unsafe shutdown meant widespread breakage, but it's no longer
a reasonable filesystem for any non-special use.

James Byrne 085a3a8fdf ABI: Update dev-kmsg documentation to match current kernel behaviour
Commit 5aa068ea40 ("printk: remove games with previous record flags")
abolished the practice of setting the log flag to 'c' for the first
continuation line and '+' for subsequent lines. Now all continuation
lines are flagged with 'c' and '+' is never used.

Update the 'dev-kmsg' documentation to remove the reference to the
obsolete '+' flag. In addition, state explicitly that only 8 bits of the
<N> syslog prefix are used for the facility number when writing to
/dev/kmsg.

ASoC: meson: add reset binding
The g12a audio subsystem, which is a derivative of the axg subsystem,
provides a dedicated reset line for each of the audio components.

The axg did not provide that and it is unclear if/when these reset are
required. The reset already helped solve a channel mapping issue on the
tdm formatter devices. Let's add the reset binding for the other
components, so we can describe this in DT. We'll use it later on
in the driver when/if needed.

====================
pull-request: can-next 2019-09-04 j1939

this is a pull request for net-next/master consisting of 21 patches.

the first 12 patches are by me and target the CAN core infrastructure.
They clean up the names of variables , structs and struct members,
convert can_rx_register() to use max() instead of open coding it and
remove unneeded code from the can_pernet_exit() callback.

The next three patches are also by me and they introduce and make use of
the CAN midlayer private structure. It is used to hold protocol specific
per device data structures.

The next patch is by Oleksij Rempel, switches the
&net->can.rcvlists_lock from a spin_lock() to a spin_lock_bh(), so that
it can be used from NAPI (soft IRQ) context.

The next 4 patches are by Kurt Van Dijck, he first updates his email
address via mailmap and then extends sockaddr_can to include j1939
members.

The final patch is the collective effort of many entities (The j1939
authors: Oliver Hartkopp, Bastian Stender, Elenita Hinds, kbuild test
robot, Kurt Van Dijck, Maxime Jayat, Robin van der Gracht, Oleksij
Rempel, Marc Kleine-Budde). It adds support of SAE J1939 protocol to the
CAN networking stack.

SAE J1939 is the vehicle bus recommended practice used for communication
and diagnostics among vehicle components. Originating in the car and
heavy-duty truck industry in the United States, it is now widely used in
other parts of the world.

P.S.: This pull request doesn't invalidate my last pull request:

this is a pull request for net-next/master consisting of 15 patches.

The first patch is by Christer Beskow, targets the kvaser_pciefd driver
and fixes the PWM generator's frequency.

The next three patches are by Dan Murphy, the tcan4x5x is updated to use
a proper interrupts/interrupt-parent DT binding to specify the devices
IRQ line. Further the unneeded wake ups of the device is removed from
the driver.

A patch by me for the mcp25xx driver removes the deprecated board file
setup example. Three patches by Andy Shevchenko simplify clock handling,
update the driver from OF to device property API and simplify the
mcp251x_can_suspend() function.

The remaining 7 patches are by me and clean up checkpatch warnings in
the generic CAN device infrastructure.

Daniel Mack 2a4bfd023f hwrng: timeriomem - relax check on memory resource size
The timeriomem_rng driver only accesses the first 4 bytes of the given
memory area and currently, it also forces that memory resource to be
exactly 4 bytes in size.

This, however, is problematic when used with device-trees that are
generated from things like FPGA toolchains, where the minimum size
of an exposed memory block may be something like 4k.

Hence, let's only check for what's needed for the driver to operate
properly; namely that we have enough memory available to read the
random data from.

Nicholas Piggin 2275d7b575 powerpc/64s/radix: introduce options to disable use of the tlbie instruction
Introduce two options to control the use of the tlbie instruction. A
boot time option which completely disables the kernel using the
instruction, this is currently incompatible with HASH MMU, KVM, and
coherent accelerators.

And a debugfs option can be switched at runtime and avoids using tlbie
for invalidating CPU TLBs for normal process and kernel address
mappings. Coherent accelerators are still managed with tlbie, as will
KVM partition scope translations.

Cross-CPU TLB flushing is implemented with IPIs and tlbiel. This is a
basic implementation which does not attempt to make any optimisation
beyond the tlbie implementation.

This is useful for performance testing among other things. For example
in certain situations on large systems, using IPIs may be faster than
tlbie as they can be directed rather than broadcast. Later we may also
take advantage of the IPIs to do more interesting things such as trim
the mm cpumask more aggressively.

SAE J1939 is the vehicle bus recommended practice used for communication
and diagnostics among vehicle components. Originating in the car and
heavy-duty truck industry in the United States, it is now widely used in
other parts of the world.

J1939, ISO 11783 and NMEA 2000 all share the same high level protocol.
SAE J1939 can be considered the replacement for the older SAE J1708 and
SAE J1587 specifications.

Stefan-gabriel Mirea 09864c1cdf tty: serial: Add linflexuart driver for S32V234
Introduce support for LINFlex driver, based on:
- the version of Freescale LPUART driver after commit b3e3bf2ef2 ("Merge
  4.0-rc7 into tty-next");
- commit abf1e0a980 ("tty: serial: fsl_lpuart: lock port on console
  write").
In this basic version, the driver can be tested using initramfs and relies
on the clocks and pin muxing set up by U-Boot.

Remarks concerning the earlycon support:

- LinFlexD does not allow character transmissions in the INIT mode (see
  section 47.4.2.1 in the reference manual[1]). Therefore, a mutual
  exclusion between the first linflex_setup_watermark/linflex_set_termios
  executions and linflex_earlycon_putchar was employed and the characters
  normally sent to earlycon during initialization are kept in a buffer and
  sent afterwards.

- Empirically, character transmission is also forbidden within the last 1-2
  ms before entering the INIT mode, so we use an explicit timeout
  (PREINIT_DELAY) between linflex_earlycon_putchar and the first call to
  linflex_setup_watermark.

- U-Boot currently uses the UART FIFO mode, while this driver makes the
  transition to the buffer mode. Therefore, the earlycon putchar function
  matches the U-Boot behavior before initializations and the Linux behavior
  after.

David S. Miller 94810bd365 mlx5-updates-2019-09-01 (Software steering support)
Abstract:
 --------
 Mellanox ConnetX devices supports packet matching, packet modification and
 redirection. These functionalities are also referred to as flow-steering.
 To configure a steering rule, the rule is written to the device owned
 memory, this memory is accessed and cached by the device when processing
 a packet.
 Steering rules are constructed from multiple steering entries (STE).
 
 Rules are configured using the Firmware command interface. The Firmware
 processes the given driver command and translates them to STEs, then
 writes them to the device memory in the current steering tables.
 This process is slow due to the architecture of the command interface and
 the processing complexity of each rule.
 
 The highlight of this patchset is to cut the middle man (The firmware) and
 do steering rules programming into device directly from the driver, with
 no firmware intervention whatsoever.
 
 Motivation:
 -----------
 Software (driver managed) steering allows for high rule insertion rates
 compared to the FW steering described above, this is achieved by using
 internal RDMA writes to the device owned memory instead of the slow
 command interface to program steering rules.
 
 Software (driver managed) steering, doesn't depend on new FW
 for new steering functionality, new implementations can be done in the
 driver skipping the FW layer.
 
 Performance:
 ------------
 The insertion rate on a single core using the new approach allows
 programming ~300K rules per sec. (Done via direct raw test to the new mlx5
 sw steering layer, without any kernel layer involved).
 
 Test: TC L2 rules
 33K/s with Software steering (this patchset).
 5K/s  with FW and current driver.
 This will improve OVS based solution performance.
 
 Architecture and implementation details:
 ----------------------------------------
 Software steering will be dynamically selected via devlink device
 parameter. Example:
 $ devlink dev param show pci/0000:06:00.0 name flow_steering_mode
           pci/0000:06:00.0:
           name flow_steering_mode type driver-specific
           values:
              cmode runtime value smfs
 
 mlx5 software steering module a.k.a (DR - Direct Rule) is implemented
 and contained in mlx5/core/steering directory and controlled by
 MLX5_SW_STEERING kconfig flag.
 
 mlx5 core steering layer (fs_core) already provides a shim layer for
 implementing different steering mechanisms, software steering will
 leverage that as seen at the end of this series.
 
 When Software Steering for a specific steering domain
 (NIC/RDMA/Vport/ESwitch, etc ..) is supported, it will cause rules
 targeting this domain to be created using  SW steering instead of FW.
 
 The implementation includes:
 Domain - The steering domain is the object that all other object resides
     in. It holds the memory allocator, send engine, locks and other shared
     data needed by lower objects such as table, matcher, rule, action.
     Each domain can contain multiple tables. Domain is equivalent to
     namespaces e.g (NIC/RDMA/Vport/ESwitch, etc ..) as implemented
     currently in mlx5_core fs_core (flow steering core).
 
 Table - Table objects are used for holding multiple matchers, each table
     has a level used to prevent processing loops. Packets are being
     directed to this table once it is set as the root table, this is done
     by fs_core using a FW command. A packet is being processed inside the
     table matcher by matcher until a successful hit, otherwise the packet
     will perform the default action.
 
 Matcher - Matchers objects are used to specify the fields mask for
     matching when processing a packet. A matcher belongs to a table, each
     matcher can hold multiple rules, each rule with different matching
     values corresponding to the matcher mask. Each matcher has a priority
     used for rule processing order inside the table.
 
 Action - Action objects are created to specify different steering actions
     such as count, reformat (encapsulate, decapsulate, ...), modify
     header, forward to table and many other actions. When creating a rule
     a sequence of actions can be provided to be executed on a successful
     match.
 
 Rule - Rule objects are used to specify a specific match on packets as
     well as the actions that should be executed. A rule belongs to a
     matcher.
 
 STE - This layer is used to hold the specific STE format for the device
     and to convert the requested rule to STEs. Each rule is constructed of
     an STE chain, Multiple rules construct a steering graph. Each node in
     the graph is a hash table containing multiple STEs. The index of each
     STE in the hash table is being calculated using a CRC32 hash function.
 
 Memory pool - Used for managing and caching device owned memory for rule
     insertion. The memory is being allocated using DM (device memory) API.
 
 Communication with device - layer for standard RDMA operation using  RC QP
     to configure the device steering.
 
 Command utility - This module holds all of the FW commands that are
     required for SW steering to function.
 
 Patch planning and files:
 -------------------------
 1) First patch, adds the support to Add flow steering actions to fs_cmd
 shim layer.
 
 2) Next 12 patch will add a file per each Software steering
 functionality/module as described above. (See patches with title: DR, *)
 
 3) Add CONFIG_MLX5_SW_STEERING for software steering support and enable
 build with the new files
 
 4) Next two patches will add the support for software steering in mlx5
 steering shim layer
 net/mlx5: Add API to set the namespace steering mode
 net/mlx5: Add direct rule fs_cmd implementation
 
 5) Last two patches will add the new devlink parameter to select mlx5
 steering mode, will be valid only for switchdev mode for now.
 Two modes are supported:
     1. DMFS - Device managed flow steering
     2. SMFS - Software/Driver managed flow steering.
 
     In the DMFS mode, the HW steering entities are created through the
     FW. In the SMFS mode this entities are created though the driver
     directly.
 
     The driver will use the devlink steering mode only if the steering
     domain supports it, for now SMFS will manages only the switchdev
     eswitch steering domain.
 
     User command examples:
     - Set SMFS flow steering mode::
 
         $ devlink dev param set pci/0000:06:00.0 name flow_steering_mode value "smfs" cmode runtime
 
     - Read device flow steering mode::
 
         $ devlink dev param show pci/0000:06:00.0 name flow_steering_mode
