Pull livepatching updates from Jiri Kosina:

 - RO/NX attribute fixes for patch module relocations from Josh
   Poimboeuf.  As part of this effort, module.c has been cleaned up as
   well and livepatching is piggy-backing on this cleanup.  Rusty is OK
   with this whole lot going through livepatching tree.

 - symbol disambiguation support from Chris J Arges.  That series is
   also

        Reviewed-by: Miroslav Benes <mbenes@suse.cz>

   but this came in only after I've alredy pushed out.  Didn't want to
   rebase because of that, hence I am mentioning it here.

 - symbol lookup fix from Miroslav Benes

35f739679a iio: dac: mcp4725: Add basic support for MCP4726
MCP4726 is a single channel 12-bit DAC.  We can support MCP4726 with
a little changes to mcp4725 driver.  In power-down mode, they have
different selection of VOUT pull-down registers.

MCP4726 also has features:
 - Output gain options: 1x, 2x
 - Voltage reference selection: VDD, VREF (Unbuffered or Buffered)

But these are not supported in this change. (1x gain, VDD is selected)

33b711269a watchdog: Read device status through sysfs attributes
This patch adds following attributes to watchdog device's sysfs interface
to read its different status.

* state - reads whether device is active or not
* identity - reads Watchdog device's identity string.
* timeout - reads current timeout.
* timeleft - reads timeleft before watchdog generates a reset
* bootstatus - reads status of the watchdog device at boot
* status - reads watchdog device's  internal status bits
* nowayout - reads whether nowayout feature was set or not

Testing with iTCO_wdt:
 # cd /sys/class/watchdog/watchdog1/
 # ls
bootstatus  dev  device  identity  nowayout  power  state
subsystem  timeleft  timeout  uevent
 # cat identity
iTCO_wdt
 # cat timeout
30
 # cat state
inactive
 # echo > /dev/watchdog1
 # cat timeleft
26
 # cat state

045959db65 IB/cma: Add configfs for rdma_cm
Users would like to control the behaviour of rdma_cm.
For example, old applications which don't set the
required RoCE gid type could be executed on RoCE V2
network types. In order to support this configuration,
we implement a configfs for rdma_cm.

In order to use the configfs, one needs to mount it and
mkdir <IB device name> inside rdma_cm directory.

The patch adds support for a single configuration file,
default_roce_mode. The mode can either be "IB/RoCE v1" or
"RoCE v2".

This patch set adds attributes of net device and gid type to each GID
in the GID table. Users that use verbs directly need to specify
the GID index. Since the same GID could have different types or
associated net devices, users should have the ability to query the

513072d90a usb: core: lpm: add sysfs node for usb3 lpm permit
USB3 LPM is default on in Linux kernel if both xHCI host controller
and the USB devices declare to be LPM-capable. Unfortunately, some
devices are known to work well with LPM disabled, but to be broken
if LPM is enabled, although it declares the LPM capability.  Users
won't be able to use this kind of devices, until someone puts them
in the kernel blacklist and gets the kernel upgraded.

This patch adds a sysfs node to permit or forbit USB3 LPM U1 or U2
entry for a port. The settings apply to both before and after device
enumeration. Supported values are "0" - neither u1 nor u2 permitted,
"u1" - only u1 is permitted, "u2" - only u2 is permitted, "u1_u2" -
both u1 and u2 are permitted. With this interface, users can use an
LPM-unfriendly USB device on a released Linux kernel.

Commit 655fe4effe ("usbcore: add sysfs support to xHCI usb3

doesn't show the correct status of USB3 U1 and U2 LPM status.

This patch fixes this by replacing usb3_hardware_lpm with two
nodes, usb3_hardware_lpm_u1 (for U1) and usb3_hardware_lpm_u2
(for U2), and recording the U1/U2 LPM status in right places.

This patch should be back-ported to kernels as old as 4.3,
that contains Commit 655fe4effe ("usbcore: add sysfs support
to xHCI usb3 hardware LPM").

Seymour, Shane M
d9b43a10f0 st: allow debug output to be enabled or disabled via sysfs
Change st driver to allow enabling or disabling debug output
via sysfs file /sys/bus/scsi/drivers/st/debug_flag.

Previously the only way to enable debug output was:

1. loading the driver with the module parameter debug_flag=1
2. an ioctl call (this method was also the only way to dynamically
disable debug output).

To use the ioctl you need a second tape drive (if you are
actively testing the first tape drive) since a second process
cannot open the first tape drive if it is in use.

The this change is only functional if the value of the macro
DEBUG in st.c is a non-zero value (which it is by default).

8d2f8479da HID: roccat: Fixed resubmit: Deprecating most Roccat sysfs attributes
Deprecates all Roccat sysfs attributes except the ones for the old Kone by
moving abi descriptions from testing to obsolete.  For most devices everything
can be done using the hidraw ioctls HIDIOCGFEATURE and HIDIOCSFEATURE, so I
would suggest future removal of device specific drivers.  The userspace tools
don't use these attributes for a year now.  The first Kone is not fully
HID-compliant and will still need a module.

of windows in multiblock mode. Userspace can read the buffers via mmap()ing

b27a6a3f97 intel_th: Add Global Trace Hub driver
Global Trace Hub (GTH) is the central component of Intel TH architecture;
it carries out switching between the trace sources and trace outputs, can
enable/disable tracing, perform STP encoding, internal buffering, control
backpressure from outputs to sources and so on.

This property is also reflected in the software model; GTH (switch) driver
is required for the other subdevices to probe, because it matches trace
output devices against its output ports and configures them accordingly.

It also implements an interface for output ports to request trace enabling
or disabling and a few other useful things.

For userspace, it provides an attribute group "masters", which allows
configuration of per-master trace output destinations for up to master 255
and "256+" meaning "masters 256 and above". It also provides an attribute
group to discover and configure some of the parameters of its output ports,
called "outputs". Via these the user can set up data retention policy for
an individual output port or check if it is in reset state.

39f4034693 intel_th: Add driver infrastructure for Intel(R) Trace Hub devices
Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that
produce, switch and output trace data from multiple hardware and
software sources over several types of trace output ports encoded
in System Trace Protocol (MIPI STPv2) and is intended to perform
full system debugging.

For these subdevices, we create a bus, where they can be discovered
and configured by userspace software.

This patch creates this bus infrastructure, three types of devices
(source, output, switch), resource allocation, some callback mechanisms
to facilitate communication between the subdevices' drivers and some
common sysfs attributes.

7bd1d4093c stm class: Introduce an abstraction for System Trace Module devices
A System Trace Module (STM) is a device exporting data in System Trace
Protocol (STP) format as defined by MIPI STP standards. Examples of such
devices are Intel(R) Trace Hub and Coresight STM.

This abstraction provides a unified interface for software trace sources
to send their data over an STM device to a debug host. In order to do
that, such a trace source needs to be assigned a pair of master/channel
identifiers that all the data from this source will be tagged with. The
STP decoder on the debug host side will use these master/channel tags to
distinguish different trace streams from one another inside one STP
stream.

This abstraction provides a configfs-based policy management mechanism
for dynamic allocation of these master/channel pairs based on trace
source-supplied string identifier. It has the flexibility of being
defined at runtime and at the same time (provided that the policy
definition is aligned with the decoding end) consistency.

For userspace trace sources, this abstraction provides write()-based and
mmap()-based (if the underlying stm device allows this) output mechanism.

For kernel-side trace sources, we provide "stm_source" device class that
can be connected to an stm device at run time.

8d2faea672 This is the bulk of GPIO changes for the v4.3 kernel cycle:
Core changes:
 
 - Root out the wrapper devm_gpiod_get() and gpiod_get() etc
   versions of the descriptor calls that did not use the flags
   argument on the end. This was around for too long and eventually
   Uwe Kleine-König took the time to clean it out and the last
   users are removed along with the macros in this tag. In several
   cases the use of flags simplifies the code. For this reason we
   have (ACKed) patches hitting in DRM, IIO, media, NFC, USB+PHY
   up until we hammer in the nail with removing the macros.
 
 - Add a fat document describing how much ready-made GPIO stuff
   we have i the kernel to discourage people from reinventing
   a square wheel in userspace, as so often happens.
 
 - Create a separate lockdep class for each instance of a GPIO
   IRQ chip instead of using one class for all chips, as the current
   code will not work with systems with several GPIO chips doing
   lockdep debugging.
 
 - Protect against driver unloading also when a GPIO line is only
   used as IRQ for the GPIOLIB_IRQCHIP helpers.
 
 - If the GPIO chip has no designated owner, assign the parent
   device driver owner as owner.
 
 - Consolidation of chained IRQ handler install/remove replacing
   all call sites where irq_set_handler_data() and
   irq_set_chained_handler() were done in succession with a
   combined call to irq_set_chained_handler_and_data(). This
   series was created by Thomas Gleixner after the problem was
   observed by Russell King.
 
 - Tglx also made another series of patches switching
   __irq_set_handler_locked() for irq_set_handler_locked() which
   is way cleaner.
 
 - Tglx and Jiang Liu wrote a good bunch of patches to make use of
   irq_desc_get_xxx() accessors and avoid looking up irq_descs
   from IRQ numbers. The goal is to get rid of the irq number
   from the handlers in the IRQ flow which is nice.
 
 - Rob Herring killed off the set_irq_flags() for all GPIO
   drivers. This was an ARM specific function that is replaced
   with the generic irq_modify_status() where special flags
   are actually needed.
 
 - When an OF node has a pin range for its GPIOs, return
   -EPROBE_DEFER if the pin controller isn't available.
   Pretty logical, yet needed to be fixed.
 
 - If a driver using GPIOLIB_IRQCHIP has its own
   irq_*_resources call back, then call these instead of the
   defaults provided by the GPIOLIB.
 
 - Fix an undocumented ABI hole: named GPIOs were not
   properly documented.
 
 Driver improvements:
 
 - Add get_direction() support to the generic GPIO driver, it's
   strange that we didn't have that before.
 
 - Make it possible to have input-only GPIO chips using the
   generic GPIO driver.
 
 - Clean out platform data support from the Emma Mobile (EM)
   driver
 
 - Finegrained runtime PM support for the RCAR driver.
 
 - Support r8a7795 (R-car H3) in the RCAR driver.
 
 - Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.
 
 - Some consolidation and new support in the MPC8xxx driver,
   we now support MPC5125.
 
 - Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
   spinlocks making it work better with the realime patches.
 
 - Interrupt support for the EXTRAXFS GPIO driver.
 
 - Make the ETRAXFS GPIO driver support also ARTPEC-3.
 
 - Interrupt and wakeup support for the BRCMSTB driver, also for
   wakeup from S5 cold boot.
 
 - Mask MXC IRQs during suspend.
 
 - Improve OMAP2 GPIO set_debounce() to work according to spec.
 
 - The VF610 driver handles IRQs properly.
 
 New drivers:
 
 - ZTE ZX GPIO driver.

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.3 kernel cycle.

  There is quite a lot going on in the GPIO subsystem this merge window,
  so the main matter is decribed below.

  The hits in other subsystems when making the GPIO flags optional are
  all ACKed by their respective subsystem maintainers.

  Core changes:

   - Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions

Here's the big USB and PHY patchset for 4.3-rc1.
 
 As usual, the majority of the changes are in the USB gadget portion of
 the tree, lots of little changes all over the place for bugs and new
 hardware.  Other than that, the normal mix of new hardware support and
 bugfixes.
 
 All have been in linux-next with no reported issues.

a3fbedf98f usb: patches for v4.3 merge window
New support for Allwinne SoC on the MUSB driver has been added to the list of
 glue layers. MUSB also got support for building all DMA engines in one binary;
 this will be great for distros.
 
 DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely on
 tracing to debug DWC3. There was also a fix for memory corruption with EP0 when
 maxpacket size transfers are > 512 bytes.
 
 Robert's EP capabilities flags is making EP selection a lot simpler. UDCs are
 now required to set these flags up when adding endpoints to the framework.
 
 Other than these, we have the usual set of miscelaneous cleanups and minor
 fixes.

Provide a kernel API and a sysfs entry which allow a user to specify
that when a card is PERSTed, it's image will stay the same, allowing
it to participate in EEH.

cxl_reset is used to reflash the card. In that case, we cannot safely
assert that the image will not change. Therefore, disallow cxl_reset
if the flag is set.

1c46ae0af6 Second set of new device support, features and cleanup for the 4.3 cycle.
Take 2 also includes a fix set that was too late for the 4.2 cycle.
 
 As we had a lot of tools and docs work in this set, I have broken those
 out into their own categories in this description.
 
 Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'.
 * Poll functions for both event chardev and the buffer one were returning
   negative error codes (via a positive value).
 * A recent change to lsiio adding some error handling that was wrong and
   stopped the tool working.
 * bmg160 was missing some dependencies in Kconfig
 * berlin2-adc had a misshandled register (wrote a value rather than a bitmap)
 
 New device support
 * TI opt3001 light sensor
 * TXC PA12 ALS and proximity sensor.
 * mcp3301 ADC support (in mcp320x driver)
 * ST lsm303agr accelerometer and magnetometer drivers (plus some st-sensors
   common support to allow different WHOAMI register addresses, devices with
   fixed scale and allow interrupt equiped magnetometers).
 * ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver)
 * ADIS16266 gyro (in the adis16260 driver)
 * ADIS16137 gyro (in the adis16136 driver)
 
 New functionality
 * mmc35240 DT bindings.
 * Inverse unit conversion macros to aid handing of values written to sysfs
   attributes.
 
 Core cleanup
 * Forward declaration of struct iio_trigger to avoid a compile warning.
 
 Driver cleanup / fixes
 * mxs-lradc
   - Clarify which parts are supported.
   - Fix spelling erorrs.
   - Missing/extra includes
   - reorder includes
   - add datasheet name listings for all usable channels (to allow them
     to be bound by name from consumer drivers)
 * acpi-als - add some function prefixes as per general iio style.
 * bmc150_magn - replace a magic value with the existing define.
 * vf610 - determine possible sample frequencies taking into account the
   electrical characteristics (defining a minimum sample time)
 * dht11
   - whitespace
   - additional docs
   - avoid mulitple assignments in one line
   - Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick
     previously used for timing.
 * Fix all drivers that consider 0 a valid IRQ for historical reasons.
 * Export I2C module alias info where previously missing (to allow autoprobing)
 * Export OF module alias info where previously missing.
 * mmc35240 - switch some variables into arrays to improve readability.
 * mlx90614 - define some magic numbers for readability.
 * bmc150_magn
   - expand area locked by a mutex to cover all the use of the
     data->buffer.
   - use descriptive naming for a mask instead of a magic value.
 * berin2-adc
   - pass up an error code rather that a generic error
   - constify the iio_chan_spec
   - some other little tidy ups.
 * stk8312
   - fix a dependency on triggered buffers in kconfig
   - add a check for invalid attribute values
   - improve error handling by returning error codes where possible and
     return immediately where relevant
   - rework macro defs to use GENMASK etc
   - change some variable types to reduce unnecessary casting
   - clean up code style
   - drop a local buffer copy for bulk reads and use the one in data->buffer
      instead.
 * adis16400 - the adis16448 gyroscope scale was wrong.
 * adis16480 - some more wrong scales for various parts.
 * adis16300 - has an undocumented product id and serial number registers so
   use them.
 * iio_simple_dummy - fix some wrong code indentation.
 * bmc150-accel - use the chip ID to detect the chip present rather than
   verifying the expected part was there.  This was in response to a wrong
   ACPI entry on the WinBook TW100.
 * mma8452
   - fix _get_hp_filter_index
   - drop a double include
   - pass up an error code rather than rewriting it
   - range check input values to attribute writes
   - register defs tidy up using GENMASK and reordering them to be easier to
     follow.
   - various coding style cleanups
   - put the Kconfig entry in the write place (alphabetically).
 
 Tools related
 * Tools cleanup - drop an explicity NULL comparison, some unnecessary braces,
   use the ARRAY_SIZE macro, send error messages to stderr instead of dropping
   them in the middle of normal output.
 * Fix tools to allow that scale and offset attributes are optional.
 * More tools fixes including allowing true 32bit data (previously an overflow
   prevented more than 31bits)
 * Drop a stray header guard that ended up in a c file.
 * Make calc_digits static as it isn't exported or in the header.
 * Set ci_array pointer to NULL after free as a protection against non safe
   usage of the tools core code.  Also convert a double pointer to a single
   one as the extra level of indirection was unnecessary.
 
 Docs
 * DocBook introduction by Daniel Baluta.  Glad we are beginning to
   draw together some more introductory docs to suplement the various
   tools / examples.
 * Drop bytes_per_datum sysfs attribute docs as it no longer exists.
 * A whole load of missing / fixing of kernel-doc for the core of IIO.
 * Document the trigger name sysfs attribute in the ABI docs.
 * Minor typos in the ABI docs related to power down modes.

* mmc35240 - switch some variables into arrays to improve readability.
* mlx90614 - define some magic numbers for readability.
* bmc150_magn
  - expand area locked by a mutex to cover all the use of the
    data->buffer.
  - use descriptive naming for a mask instead of a magic value.
* berin2-adc
  - pass up an error code rather that a generic error
  - constify the iio_chan_spec
  - some other little tidy ups.
* stk8312
  - fix a dependency on triggered buffers in kconfig
  - add a check for invalid attribute values
  - improve error handling by returning error codes where possible and
    return immediately where relevant
  - rework macro defs to use GENMASK etc
  - change some variable types to reduce unnecessary casting
  - clean up code style
  - drop a local buffer copy for bulk reads and use the one in data->buffer
     instead.
* adis16400 - the adis16448 gyroscope scale was wrong.
* adis16480 - some more wrong scales for various parts.
* adis16300 - has an undocumented product id and serial number registers so
  use them.
* iio_simple_dummy - fix some wrong code indentation.
* bmc150-accel - use the chip ID to detect the chip present rather than
  verifying the expected part was there.  This was in response to a wrong
  ACPI entry on the WinBook TW100.
* mma8452
  - fix _get_hp_filter_index
  - drop a double include
  - pass up an error code rather than rewriting it
  - range check input values to attribute writes
  - register defs tidy up using GENMASK and reordering them to be easier to
    follow.
  - various coding style cleanups
  - put the Kconfig entry in the write place (alphabetically).

Tools related
* Tools cleanup - drop an explicity NULL comparison, some unnecessary braces,
  use the ARRAY_SIZE macro, send error messages to stderr instead of dropping
  them in the middle of normal output.
* Fix tools to allow that scale and offset attributes are optional.
* More tools fixes including allowing true 32bit data (previously an overflow
  prevented more than 31bits)
* Drop a stray header guard that ended up in a c file.
* Make calc_digits static as it isn't exported or in the header.
* Set ci_array pointer to NULL after free as a protection against non safe
  usage of the tools core code.  Also convert a double pointer to a single
  one as the extra level of indirection was unnecessary.

Docs
* DocBook introduction by Daniel Baluta.  Glad we are beginning to
  draw together some more introductory docs to suplement the various
  tools / examples.
* Drop bytes_per_datum sysfs attribute docs as it no longer exists.
* A whole load of missing / fixing of kernel-doc for the core of IIO.
* Document the trigger name sysfs attribute in the ABI docs.
* Minor typos in the ABI docs related to power down modes.

cd196ac3fa coresight-etm4x: Change the name of the ctxid_val to ctxid_pid
'ctxid_val' array was used to store the value of ETM context ID comparator
which actually stores the process ID to be traced, so using 'ctxid_pid' as
its name instead make it easier to understand.

This patch also changes the ABI, it is normally not allowed, but
fortunately it is a testing ABI and very new for now. Nevertheless,
if you don't think it should be changed, we could always add an alias
for userspace.

7f4a633d21 twl4030_charger: add software controlled linear charging mode.
Add a 'continuous' option for usb charging which enables
the "linear" charging mode of the twl4030.

Linear charging does a good job with not-so-reliable power sources.
Auto mode does not work well as it switches off when voltage drops
momentarily.  Care must be taken not to over-charge.

It was used with a bike hub dynamo since a year or so. In that case
there are automatically charging stops when the cyclist needs a break.
