Linus Torvalds 616d8cf0fa ARM: SoC fixes for 4.16
Here are are a couple of last-minute fixes for 4.16, mostly for
 regressions. As usual, the majory are device tree changes:
 
 - USB 3 support on rk3399 didn't work and is being reverted for now
 
 - One fix for an old suspend/resume bug on rk3399
 
 - A few regulator related fixes on Banana Pi M2, and on imx7d-sdb
 
 - A boot regression fix for all Aspeed SoCs failing to find
   their memory
 
 - One more dtc warning fix
 
 The other changes are:
 
 - A few updates to the MAINTAINERS file
 
 - A revert for an incorrect orion5x cleanup
 
 - Two power management fixes for OMAP

Russell King 18bd49043c MAINTAINERS: demote ARM port to "odd fixes"
As of the start of 2018, I am no longer paid to support the core 32-bit
ARM architecture code.  This means that this code is no longer
commercially supported, and is now only supported through voluntary
effort.

I will continue to merge patches as and when able, but this will be at a
lower priority than before (which means a longer latency.) I have also
be scaled back the amount of time spent reading email, so email that is
intended for my attention needs to make itself plainly obvious, or I
will miss it.

In an attempt to reduce the amount of email Cc'd to me, exclude
arch/arm/boot/dts from the maintainers patterns, but add entries for the
SolidRun platforms I look after.

Vitaly Kuznetsov 5a48580322 x86/hyper-v: move hyperv.h out of uapi
hyperv.h is not part of uapi, there are no (known) users outside of kernel.
We are making changes to this file to match current Hyper-V Hypervisor
Top-Level Functional Specification (TLFS, see:
https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/tlfs)
and we don't want to maintain backwards compatibility.

Move the file renaming to hyperv-tlfs.h to avoid confusing it with
mshyperv.h. In future, all definitions from TLFS should go to it and
all kernel objects should go to mshyperv.h or include/linux/hyperv.h.

David S. Miller 03fe2debbb Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Fun set of conflict resolutions here...

For the mac80211 stuff, these were fortunately just parallel
adds.  Trivially resolved.

In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.

In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.

The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.

The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:

====================

    Due to bug fixes found by the syzkaller bot and taken into the for-rc
    branch after development for the 4.17 merge window had already started
    being taken into the for-next branch, there were fairly non-trivial
    merge issues that would need to be resolved between the for-rc branch
    and the for-next branch.  This merge resolves those conflicts and
    provides a unified base upon which ongoing development for 4.17 can
    be based.

    Conflicts:
            drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f95
            (IB/mlx5: Fix cleanup order on unload) added to for-rc and
            commit b5ca15ad7e (IB/mlx5: Add proper representors support)
            add as part of the devel cycle both needed to modify the
            init/de-init functions used by mlx5.  To support the new
            representors, the new functions added by the cleanup patch
            needed to be made non-static, and the init/de-init list
            added by the representors patch needed to be modified to
            match the init/de-init list changes made by the cleanup
            patch.
    Updates:
            drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
            prototypes added by representors patch to reflect new function
            names as changed by cleanup patch
            drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
            stage list to match new order from cleanup patch

Hans de Goede f6fb9ec02b usb: roles: Add Intel xHCI USB role switch driver
Various Intel SoCs (Cherry Trail, Broxton and others) have an internal USB
role switch for swiching the OTG USB data lines between the xHCI host
controller and the dwc3 gadget controller.

Note on some Cherry Trail systems there is ACPI/AML code listening to
edge interrupts on the id-pin (through an _AIE ACPI method) and switching
the role between ROLE_HOST and ROLE_NONE based on the id-pin. Note it does
not set the role to ROLE_DEVICE, because device-mode is usually not used
under Windows.

The presence of AML code which modifies the cfg0 reg (on some systems)
means that our read/write/modify of cfg0 may race with the AML code
doing the same to avoid this we take the global ACPI lock while doing
the read/write/modify.

David Lechner 2d17269151 clk: davinci: New driver for davinci PLL clocks
This adds a new driver for mach-davinci PLL clocks. This is porting the
code from arch/arm/mach-davinci/clock.c to the common clock framework.
Additionally, it adds device tree support for these clocks.

The ifeq ($(CONFIG_COMMON_CLK), y) in the Makefile is needed to prevent
compile errors until the clock code in arch/arm/mach-davinci is removed.

Note: although there are similar clocks for TI Keystone we are not able
to share the code for a few reasons. The keystone clocks are device tree
only and use legacy one-node-per-clock bindings. Also the register
layouts are a bit different, which would add even more if/else mess
to the keystone clocks. And the keystone PLL driver doesn't support
setting clock rates.

It is based from qemu/docs/specs/fw_cfg.txt which references
qemu/include/hw/nvram/fw_cfg_keys.h "for the most up-to-date and
authoritative list" & vmcoreinfo.txt. Those files don't have an
explicit license, but qemu/hw/nvram/fw_cfg.c is BSD-license, so
Michael S. Tsirkin suggested to use the same license.

The patch intentionally left out DMA & vmcoreinfo structures &

The last SoC (ARTPEC-3) with a CRIS main CPU was launched in 2008.

Arnd Bergmann bb9d812643 arch: remove tile port
The Tile architecture port was added by Chris Metcalf in 2010, and
maintained until early 2018 when he orphaned it due to his departure
from Mellanox, and nobody else stepped up to maintain it. The product
line is still around in the form of the BlueField SoC, but no longer
uses the Tile architecture.

There are also still products for sale with Tile-GX SoCs, notably the
Mikrotik CCR router family. The products all use old (linux-3.3) kernels
with lots of patches and won't be upgraded by their manufacturers. There
have been efforts to port both OpenWRT and Debian to these, but both
projects have stalled and are very unlikely to be continued in the future.

Given that we are reasonably sure that nobody is still using the port
with an upstream kernel any more, it seems better to remove it now while
the port is in a good shape than to let it bitrot for a few years first.

The Analog Devices Blackfin port was added in 2007 and was rather
active for a while, but all work on it has come to a standstill
over time, as Analog have changed their product line-up.

Aaron Wu confirmed that the architecture port is no longer relevant,
and multiple people suggested removing blackfin independently because
of some of its oddities like a non-working SMP port, and the amount of
duplication between the chip variants, which cause extra work when
doing cross-architecture changes.

Arnd Bergmann b8c9c8f019 arch: remove score port
The Sunplus S+core architecture was added in 2009 by Chen Liqin,
who has been co-maintaining it with Lennox Wu <lennox.wu@gmail.com>
since then, but after they both left the company, nobody else has shown
any interest in the port and it has seen almost no activity other than
tree-wide changes.

The gcc port was removed a few years ago due to the inactivity.

While the sunplus website still advertises products with unspecified
RISC cores that might be S+core based, it's very clear that the Linux
port is completely abandoned at this point.

This removes all files related to the architecture.

The Mitsubishi/Renesas m32r architecture has been around for many years,
but the Linux port has been obsolete for a very long time as well, with
the last significant updates done for linux-2.6.14.

While some m32r microcontrollers are still being marketed by Renesas,
those are apparently no longer possible to support, mainly due to the
lack of an external memory interface.

Hirokazu Takata was the maintainer until the architecture got marked
Orphaned in 2014.

in 2016 by long-time maintainer David Howells.

The SoC product line apparently is apparently still around in the form
of the Socionext Milbeaut image processor, but this one no longer uses
the FRV CPU cores.

This removes all FRV specific files from the kernel.

Arnd Bergmann f46f11dc1e ARM SCMI support for v4.17
ARM System Control and Management Interface(SCMI)[1] is more flexible and
 easily extensible than any of the existing interfaces.
 
 Few existing as well as future ARM platforms provide micro-controllers
 to abstract various power and other system management tasks which have
 similar interfaces, both in terms of the functions that are provided by
 them, and in terms of how requests are communicated to them.
 
 There are quite a few protocols like ARM SCPI, TI SCI, QCOM RPM, Nvidia Tegra
 BPMP, and so on already. This specification is to standardize and avoid any
 further fragmentation in the design of such interface by various vendors.
 
 The current SCMI driver implementation is very basic and initial support.
 It lacks support for notifications, asynchronous/delayed response, perf/power
 statistics region and sensor register region.
 
 Mailbox is the only form of transport supported currently in the driver.
 SCMI supports interrupt based mailbox communication, where, on completion
 of the processing of a message, the caller receives an interrupt as well as
 polling for completion.
 
 SCMI is designed to minimize the dependency on the mailbox/transport
 hardware. So in terms of SCMI, each channel in the mailbox includes
 memory area, doorbell and completion interrupt.
 
 However the doorbell and completion interrupt is highly mailbox dependent
 which was bit of controversial as part of SCMI/mailbox discussions.
 
 Arnd and me discussed about the few aspects of SCMI and the mailbox framework:
 
 1. Use of mailbox framework for doorbell type mailbox controller:
    - Such hardware may not require any data to be sent to signal the remote
      about the presence of a message. The channel will have in-built
      information on how to trigger the signal to the remote.
      There are few mailbox controller drivers which are purely doorbell based.
      e.g.QCOM IPC, STM, Tegra, ACPI PCC,..etc
 
 2. Supporting other mailbox controller:
    - SCMI just needs a mechanism to signal the remote firmware. Such
      controller may need fixed message to be sent to trigger a doorbell.
      In such case we may need to get that data from DT and pass the same
      to the controller. It's not covered in the current DT binding, but
      can be extended as optional property in future.
 
      However handling notifications may be interesting on such mailbox, but
      again there is no way to interpret what the data field(remote message)
      means, it could be a bit mask or a number or don't-care.
 
 Arnd mentioned that he doesn't like the way the mailbox binding deals
 with doorbell-type hardware, but we do have quite a few precedent drivers
 already and changing the binding to add a data field would not make it any
 better, but could cause other problems. So he is happy with the status quo
 of SCMI implementation.

Linus Torvalds 97ace515f0 ARM: SoC fixes for 4.16
This is the first set of bugfixes for ARM SoCs, fixing a couple
 of stability problems, mostly on TI OMAP and Rockchips platforms:
 
 - OMAP2 hwmod clocks must be enabled in the correct order
 
 - OMAP3 Wakeup from resume through PRM IRQ was unreliable
 
 - One regression on OMAP5 caused by a kexec fix
 
 - Rockchip ethernet needs some settings for stable operation on Rock64
 
 - Rockchip based Chrombook Plus needs another clock setting for
   stable display suspend/resume
 
 - Rockchip based phyCORE-RK3288 was able to run at an invalid
   CPU clock frequency
 
 - Rockchip MMC link was sometimes unreliable
 
 - Multiple fixes to avoid crashes in the Broadcom STB DPFE driver
 
 Other minor changes include:
 
 - Devicetree fixes for incorrect hardware description (rockchip,
   omap, Gemini, amlogic)
 
 - Some MAINTAINER file updates to correct email and git addresses
 
 - Some fixes addressing 'make W=1' dtc warnings (broadcom, amlogic,
   cavium, qualcomm, hisilicon, zx)
 
 - Fixes for LTO-compilation (orion, davinci, clps711x)
 
 - One fix for an incorrect Kconfig errata selection
 
 - A memory leak in the OMAP timer driver
 
 - A kernel data leak in OMAP1 debugfs files

Sudeep Holla 99d6bdf338 cpufreq: add support for CPU DVFS based on SCMI message protocol
On some ARM based systems, a separate Cortex-M based System Control
Processor(SCP) provides the overall power, clock, reset and system
control including CPU DVFS. SCMI Message Protocol is used to
communicate with the SCP.

This patch adds a cpufreq driver for such systems using SCMI interface
to drive CPU DVFS.

Sudeep Holla 6d6a1d82ea clk: add support for clocks provided by SCMI
On some ARM based systems, a separate Cortex-M based System Control
Processor(SCP) provides the overall power, clock, reset and system
control. System Control and Management Interface(SCMI) Message Protocol
is defined for the communication between the Application Cores(AP)
and the SCP.

This patch adds support for the clocks provided by SCP using SCMI
protocol.

Sudeep Holla aa4f886f38 firmware: arm_scmi: add basic driver infrastructure for SCMI
The SCMI is intended to allow OSPM to manage various functions that are
provided by the hardware platform it is running on, including power and
performance functions. SCMI provides two levels of abstraction, protocols
and transports. Protocols define individual groups of system control and
management messages. A protocol specification describes the messages
that it supports. Transports describe the method by which protocol
messages are communicated between agents and the platform.

This patch adds basic infrastructure to manage the message allocation,
initialisation, packing/unpacking and shared memory management.

Sudeep Holla fe7be8b297 dt-bindings: arm: add support for ARM System Control and Management Interface(SCMI) protocol
This patch adds devicetree binding for System Control and Management
Interface (SCMI) Message Protocol used between the Application Cores(AP)
and the System Control Processor(SCP). The MHU peripheral provides a
mechanism for inter-processor communication between SCP's M3 processor
and AP.

SCP offers control and management of the core/cluster power states,
various power domain DVFS including the core/cluster, certain system
clocks configuration, thermal sensors and many others.

SCMI protocol is developed as better replacement to the existing SCPI
which is not flexible and easily extensible.

Nicolas Ferre 41ad9232f2 MAINTAINERS: ARM: at91: update entry for ARM/Microchip
Change the entry name and move it to its alphabetical location.
We move to ARM/Microchip instead of ARM/ATMEL to reflect the merger
that is now nearly 2 years old.
AT91 is kept as the identity of our community. The atmel pattern is
obviously kept as well. I removed the names of the different SoCs as
they are better exposed in the arch/arm/mach-at91/Kconfig entries.

We now have a shiny new Linux-kernel memory model (LKMM) and the old
tried-and-true Documentation/memory-barrier.txt.  It would be good to
keep these automatically synchronized, but in the meantime we need at
least let people know that they are related.  Will suggested adding the
Documentation/memory-barrier.txt file to the LKMM maintainership list,
thus making the LKMM maintainers responsible for both the old and the new.
This commit follows Will's excellent suggestion.

Merge tag 'iio-for-4.17a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First round of new devices, features and cleanups for IIO in the 4.17 cycle.

Outside of IIO
* Strongly typed 64bit int_sqrt function needed by the mlx90632

New device support
* adc081s
  - New driver supporting adc081s, adc101s and adc121s TI ADCs.
* ad5272
  - New driver supproting the ad5272 and ad5274 ADI digital potentiometers
    with DT bindings.
* axp20x_adc
  - support the AXP813 ADC - includes rework patches to prepare for this.
* mlx90632
  - New driver with dt bindings for this IR temperature sensor.

Features
* axp20x_adc
  - Add DT bindings and probing.
* dht11
  - The sensor has a wider range than advertised in the datasheet - support it.
* st_lsm6dsx
  - Add hardware timestamp su9pport.

Cleanups
* ABI docs
  - Update email contact for Matt Ranostay
* SPDX changes
  - Matt Ranostay has moved his drivers over to SPDX.  Currently we are making
    this an author choice in IIO.
* ad7192
  - Disable burnout current on misconfiguration.  No actually effect as
    they simply won't work otherwise.
* ad7476
  - Drop a license definition that was replicating information in SPDX tag.
* ade7758
  - Expand buf_lock to cover both buffer and state protection allowing
    unintented uses of mlock in the core to be removed.
* ade7759
  - Align parameters to opening parenthesis.
* at91_adc
  - Depend on sysfs instead of selecting it - for try wide consistency.
* ccs811
  - trivial naming type for a define.
* ep93xx
  - Drop a redundant return as a result checking platform_get_resource.
* hts221
  - Regmap conversion which simplifies the driver somewhat.
  - Clean up some restricted endian cast warnings.
  - Drop a trailing whitespace from a comment
  - Drop an unnecessary get_unaligned by changing to the right 16bit data type.
* ms5611
  - Fix coding style in the probe function (whitespace)
* st_accel
  - Use strlcpy instead of strncpy to avoid potentially truncating a string.

Vadim Pasternak 386570d76f leds: add driver for support Mellanox regmap LEDs for BMC and x86 platform
Driver obtains LED devices according to system configuration and creates
devices in form: "devicename:color:function", like
The full path is to be:
/sys/class/leds/mlxreg\:status\:amber/brightness
After timer trigger activation:
echo timer > /sys/class/leds/mlxreg\:status\:amber/trigger
Attributes for LED blinking will appaer in sysfs infrastructure:
/sys/class/leds/mlxreg\:status\:amber/delay_off
/sys/class/leds/mlxreg\:status\:amber/delay_on

LED setting is controlled through the on-board programmable devices,
which exports its register map. This device could be attached to any
bus type, for which register mapping is supported.

Merge tag 'platform-drivers-x86-v4.16-1' of git://git.infradead.org/linux-platform-drivers-x86

Pull x86 platform-driver updates from Darren Hart:
 "New model support added for Dell, Ideapad, Acer, Asus, Thinkpad, and
  GPD laptops. Improvements to the common intel-vbtn driver, including
  tablet mode, rotate, and front button support. Intel CPU support added
  for Cannonlake and platform support for Dollar Cove power button.

  Overhaul of the mellanox platform driver, creating a new
  platform/mellanox directory for the newly multi-architecture regmap
  interface.

  Significant Intel PMC update with CannonLake support, Coffeelake
  update, CPUID enumeration, module support, new read64 API, refactoring
  and cleanups.

  Revert the apple-gmux iGP IO lock, addressing reported issues with
  non-binary drivers, leaving Nvidia binary driver users to comment out
  conflicting code.

  Miscellaneous fixes and cleanups"
