"In the past, I have funnelled perf updates through the respective
architecture trees, but now that the arm/arm64 perf driver has been
largely consolidated under drivers/perf/, it makes more sense to send
a separate pull, particularly as I'm listed as maintainer for all the
files involved. I offered the branch to arm-soc, but Arnd suggested
that I just send it to you directly.
So, here is the arm/arm64 perf queue for 4.5. The main features are
described below, but the most useful change is from Drew, which
advertises our architected event mapping in sysfs so that the perf
tool is a lot more user friendly and no longer requires the use of
magic hex constants for profiling common events.

Guests running within virtual machines might be affected by SMP effects even if
the guest itself is compiled without SMP support. This is an artifact of
interfacing with an SMP host while running an UP kernel. Using mandatory
barriers for this use-case would be possible but is often suboptimal.
In particular, virtio uses a bunch of confusing ifdefs to work around
this, while xen just uses the mandatory barriers.
To better handle this case, low-level virt_mb() etc macros are made available.
These are implemented trivially using the low-level __smp_xxx macros,
the purpose of these wrappers is to annotate those specific cases.
These have the same effect as smp_mb() etc when SMP is enabled, but generate
identical code for SMP and non-SMP systems. For example, virtual machine guests
should use virt_mb() rather than smp_mb() when synchronizing against a
(possibly SMP) host.

- A stable fix for hung IO if a DM snapshot copy hit an error
- A few small cleanups in DM core and DM persistent data.

- Add ability to debug DM bufio leaks by recording stack trace when a

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control patches for the v4.5 series.
Notably I have a patch to driver core from Stephen Boyd in the pull
request, this has been ACKed by Greg so it should be OK. The internal
API needed some tweaking to allow modular Qualcomm pin controllers.
There is a bit of development history in here but it should all add up
nicely and has boiled in linux-next. For example I merged in v4.4-rc5
to get rid of some nasty merge conflicts.

[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 1.093 MB perf.data (1247 samples) ]

- Introduce the 'perf stat record/report' workflow:
Generate perf.data files from 'perf stat', to tap into the
scripting capabilities perf has instead of defining a 'perf stat'
specific scripting support to calculate event ratios, etc.
Simple example:
$ perf stat record -e cycles usleep 1
Performance counter stats for 'usleep 1':
1,134,996 cycles
0.000670644 seconds time elapsed
$ perf stat report
Performance counter stats for '/home/acme/bin/perf stat record -e cycles usleep 1':
1,134,996 cycles
0.000670644 seconds time elapsed
$
It generates PERF_RECORD_ userspace records to store the details:
$ perf report -D | grep PERF_RECORD
0xf0 [0x28]: PERF_RECORD_THREAD_MAP nr: 1 thread: 27637
0x118 [0x12]: PERF_RECORD_CPU_MAP nr: 1 cpu: 65535
0x12a [0x40]: PERF_RECORD_STAT_CONFIG

0x1da [0x18]: PERF_RECORD_STAT_ROUND
[acme@ssdandy linux]$
An effort was made to make perf.data files generated like this to
not generate cryptic messages when processed by older tools.
The 'perf script' bits need rebasing, will go up later.
- Make command line options always available, even when they depend
on some feature being enabled, warning the user about use of such
options (Wang Nan)
- Support hw breakpoint events (mem:0xAddress) in the default output
mode in 'perf script' (Wang Nan)
- Fixes and improvements for supporting annotating ARM binaries,
support ARM call and jump instructions, more work needed to have
arch specific stuff separated into tools/perf/arch/*/annotate/
(Russell King)
- Add initial 'perf config' command, for now just with a --list
command to the contents of the configuration file in use and a
basic man page describing its format, commands for doing edits and
detailed documentation are being reviewed and proof-read. (Taeung
Song)
- Allows BPF scriptlets specify arguments to be fetched using DWARF
info, using a prologue generated at compile/build time (He Kuang,
Wang Nan)
- Allow attaching BPF scriptlets to module symbols (Wang Nan)
- Allow attaching BPF scriptlets to userspace code using uprobe (Wang
Nan)
- BPF programs now can specify 'perf probe' tunables via its section
name, separating key=val values using semicolons (Wang Nan)
Testing some of these new BPF features:
Use case: get callchains when receiving SSL packets, filter then in the
kernel, at arbitrary place.

The Zodiac watchdog driver attaches additional sysfs attributes to the
watchdog device. This has a number of problems: The watchdog device
lifetime differs from the driver lifetime, and the device structure
should therefore not be accessed from drivers. Also, creating sysfs
attributes after driver registration results in a potential race condition
if user space expects the attributes to exist but they don't exist yet.
Add support for creating driver specific sysfs attributes to the watchdog
core to solve the problems.

Document what I've learned so far about the gmux so that we can
collaboratively reverse-engineer its remaining unknown bits
without everyone having to start from scratch.
The DOC sections are bound together in the gpu.tmpl DocBook
under a new vga_switcheroo "Handlers" chapter. Eventually
this should be amended with documentation about the four other
handlers that exist so far (nouveau v1 DSM, nouveau Optimus DSM,
radeon ATPX, amdgpu ATPX).
Requires kernel-doc with asciidoc support.
The EFI variable was reverse-engineered by Bruno Bierbaumer
<bruno@bierbaumer.net> and Andreas Heider <andreas@meetr.de>.
Some of the remaining open questions:
* How are vblank intervals synchronized on retinas to achieve seamless
switching? Is the DP mux capable of this? It's not mentioned in the
data sheets. Or is it done at the OS level, i.e. do we have to
synchronize vblank intervals between DRM drivers? There's a signal
coming from the panel connector and going into gmux, could this be
the vblank signal as received by the panel to properly time the
switch?
* On retinas there's an I2C bus between gmux and the connector of the
right I/O board, apparently leading to the Parade PS8401A HDMI
repeater. What is this for, is it controlled via gmux registers?
Data sheet:
http://www.paradetech.com/products/jitter-cleaning-repeaters/ps8401/
* On retinas there's an I2C bus between gmux and the LED driver.
Pre-retinas connected the LED driver to SMBUS. Are there additional
gmux registers on retinas to control it?
* The MacPro6,1 2013 also has a gmux, the same Renesas R4F2113 as the
retina MacBook Pro. The Mac Pro doesn't have a built-in display,
so what is its purpose? Power control of the dual FirePro GPUs?
Switching of the external DP/Thunderbolt ports? The iFixit teardown
clearly shows one TI HD3SS212 DisplayPort mux on the logic board next
to one of the three Thunderbolt controllers. However six muxes would
be necessary to switch all six ports between GPUs. The mux is probably
necessary for one of the display configurations allowed by Apple,
but which one?

* Registers we haven't decoded yet:
0x700 32 Bit configmap?
0x708 32 Bit power sequence?
0x712 8 Bit status of clock from panel on retinas?
0x713 8 Bit dito?
0x724 16 Bit backlight, raw value?
0x760 32 Bit backlight
0x764 32 Bit backlight
0x768 8 Bit backlight
0x76a 16 Bit backlight
0x76c 16 Bit backlight

0x77f edp/dp/hdmi probe? retina only.
* Addition by Bruno Prémont <bonbons@linux-vserver.org>:
"Missing is also precise knowledge as to what the gmux depends on.
From behavioral reports, it is somehow sensitive to VGA IO/MEM
routing (it apparently needs the routing to go to integrated GPU,
not discrete GPU).
When the routing is inappropriate backlight control IO just reads back
as 0xFF (and eventually gmux IO in general does so)."

With the MC next gen rework, what's left for media_entity_init()
is to just initialize the PADs. However, certain devices, like
a FLASH led/light doesn't have any input or output PAD.
So, there's no reason why calling media_entity_init() would be
mandatory. Also, despite its name, what this function actually
does is to initialize the PADs data. So, rename it to
media_entity_pads_init() in order to reflect that.
The media entity actual init happens during entity register,
at media_device_register_entity(). We should move init of
num_links and num_backlinks to it.

Entities should have one or more functions. Calling it as a

have more than one type.
So, rename the field as function.

of keeping something named as MEDIA_ENT_T_DEVNODE.
This change was done with this script:
for i in $(git grep -l MEDIA_ENT_T|grep -v uapi/linux/media.h); do sed s,MEDIA_ENT_T_DEVNODE_V4L,MEDIA_ENT_T_V4L2_VIDEO, <$i >a && mv a $i; done

With the new API, a link can be either between two PADs or between an interface
and an entity. So, we need to use a better name for the function that create
links between two pads.
So, rename the such function to media_create_pad_link().
No functional changes.
This patch was created via this shell script:
for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f) $(find include/ -name '*.h' -type f) ; do sed s,media_entity_create_link,media_create_pad_link,g <$i >a && mv a $i; done

Currently, media_entity_init() creates an array with the links,
allocated at init time. It provides a parameter (extra_links)
that would allocate more links than the current needs, but this
is not used by any driver.
As we want to be able to do dynamic link allocation/removal,
we'll need to change the implementation of the links. So,
before doing that, let's first remove that extra unused
parameter, in order to cleanup the interface first.

This is quite a busy release on the driver front with a lot of new
drivers being added but comparatively quiet on the core side with only
one big change going in and that a fairly straightforward refactoring.
- Conversion of the array of DAI links to a list by Mengdong Lin,
supporting dynamically adding and removing DAI links.
- Some more fixes for the topology code, though it is still not final
and ready for enabling in production. We really need to get to the
point where that can be done.
- A pile of changes for Intel SkyLake drivers which hopefully deliver
some useful initial functionality for systems with this chipset,
though there is more work still to come.
- New drivers for a number of Imagination Technologies IPs.
- Lots of new features and cleanups for the Renesas drivers.
- ANC support for WM5110.
- New driver for Atmel class D speaker drivers.

Currently syscon has a fixed configuration of 32 bits for register and
values widths. In some cases, it would be desirable to be able to
customize the value width.
For example, certain boards (like the ones manufactured by Technologic
Systems) have a FPGA that is memory-mapped, but its registers are only
16-bit wide.
This patch adds an optional "reg-io-width" DT binding for syscon that
allows to change the width for the data bus (i.e. val_bits). If this
property is provided, it will also set the register stride to
reg-io-width's value. If not provided, the default configuration is
used.

This set of changes adds support for the Tegra210 SoC and contains a

ConfigFS lacked binary attributes up until now. This patch
introduces support for binary attributes in a somewhat similar
manner of sysfs binary attributes albeit with changes that
fit the configfs usage model.
Problems that configfs binary attributes fix are everything that
requires a binary blob as part of the configuration of a resource,
such as bitstream loading for FPGAs, DTBs for dynamically created
devices etc.
Look at Documentation/filesystems/configfs/configfs.txt for internals
and howto use them.
This patch is against linux-next as of today that contains
Christoph's configfs rework.

Pull "BCM2835 drivers changes for 4.5" from Eric Anholt:
This pull request includes the bcm2835 changes for 4.5 targeting the
arm-soc next/drivers branch.
* tag 'bcm2835-drivers-next-2015-12-28' of http://github.com/anholt/linux:
ARM: bcm2835: add rpi power domain driver
dt-bindings: add rpi power domain driver bindings
ARM: bcm2835: Define two new packets from the latest firmware.
All variables required by the watchdog core to manage a watchdog are
currently stored in struct watchdog_device. The lifetime of those
variables is determined by the watchdog driver. However, the lifetime
of variables used by the watchdog core differs from the lifetime of
struct watchdog_device. To remedy this situation, watchdog drivers
can implement ref and unref callbacks, to be used by the watchdog
core to lock struct watchdog_device in memory.
While this solves the immediate problem, it depends on watchdog drivers
to actually implement the ref/unref callbacks. This is error prone,
often not implemented in the first place, or not implemented correctly.
To solve the problem without requiring driver support, split the variables
in struct watchdog_device into two data structures - one for variables
associated with the watchdog driver, one for variables associated with
the watchdog core. With this approach, the watchdog core can keep track
of its variable lifetime and no longer depends on ref/unref callbacks
in the driver. As a side effect, some of the variables originally in
struct watchdog_driver are now private to the watchdog core and no longer
visible in watchdog drivers.
As a side effect of the changes made, an ioctl will now always fail
with -ENODEV after a watchdog device was unregistered with the character
device still open. Previously, it would only fail with -ENODEV in some
situations. Also, ioctl operations are now atomic from driver perspective.
With this change, it is now guaranteed that the driver will not unregister
a watchdog between a timeout change and the subsequent ping.
The 'ref' and 'unref' callbacks in struct watchdog_driver are no longer
used and marked as deprecated.

This watchdog is instantiated in a FPGA that is memory mapped. It is
made of only one register, called the feed register. Writing to this
register will re-arm the watchdog for a given time (and enable it if it
was disable). It can be disabled by writing a special value into it.
It is part of a syscon block, and the watchdog register offset in this
block varies from board to board. This offset is passed in the syscon
property after the phandle to the syscon node.

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

The big one here is the configfs support which has been a long time in the
works but should allow for cleaner ways to do instantiation of those elements
of IIO that aren't directly connected to specific hardware. Lots of cool new
stuff we can use this for in the works!
New core stuff (basically all configfs support related)
* Configfs support
- Core support (was waiting for a configfs patch that went in around 4.4rc2)
- A little fixlet to add a configfs.h to contain a reference to the
configfs_subsystem structure.
* Some infrastructure to simplify handling of software based triggers
(i.e. ones with no actual hardware associated with them)
* A high resolution timer based trigger. This has been around for years
but until the configfs support was ready we didn't have a sensible way
of instantiating instances of it (the method used for the sysfs_trigger
has never been really satisfactory)
New Device Support
* AMS iAQ Volatile Organic Compounds sensor support.
* Freescale imx7d ADC driver
* Maxim MAX30100 oximeter driver (note that for these devices most of the
smart stuff will be in userspace - effectively they are just light sensors
with some interesting led synchronization as far as the kernel is concerned).
* Microchip mcp3421 support added to the mcp3422 driver.
* TI adc124s021 support added to the adc128s052 driver.
* TI ina219, inda226 power monitors. Note that there is an existing hwmon driver
for these parts, the usecase is somewhat different so it is unclear at this
point if the hwmon driver will eventually be replaced by a bridge from
this driver. In the meantime the Kconfig dependencies should prevent both
from being built.
New driver functionality
* us8152d power management support.
Cleanups, fixups
* Use list_for_each_entry_safe instead of list_for_each_safe with the entry
bit coded longhand.
* Select IRQ_WORK for IIO_DUMMY_EVGEN. This is a fix that somehow got lost
when the driver was moved so lets do it again.
* st-accel - drop an unused define.
* vz89x, lidar - optimize i2c transactions by using a single i2c tranfers
instead of multiple calls where supported (fall back to smbus calls as
before if not).
* Use dev_get_platdata() in staging drivers: tsl2x7x, adcs and frequency
drivers instead of direct access to the structure element.

The brd driver has never supported the ramdisk_blocksize kernel
parameter that was in the rd driver it replaced, so remove
mention of this parameter from comments and Documentation.
Commit 9db5579be4 ("rewrite rd") replaced rd with brd, keeping
a brd_blocksize variable in struct brd_device but never using it.
Commit a2cba2913c ("brd: get rid of unused members from struct
brd_device") removed the unused variable.
Commit f5abc8e758 ("Documentation/blockdev/ramdisk.txt: updates")
removed mentions of ramdisk_blocksize from that file.

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 is quite a busy release on the driver front with a lot of new

one big change going in and that a fairly straightforward refactoring.
- Conversion of the array of DAI links to a list by Mengdong Lin,
supporting dynamically adding and removing DAI links.
- Some more fixes for the topology code, though it is still not final
and ready for enabling in production. We really need to get to the
point where that can be done.
- A pile of changes for Intel SkyLake drivers which hopefully deliver
some useful initial functionality for systems with this chipset,
though there is more work still to come.
- New drivers for a number of Imagination Technologies IPs.
- Lots of new features and cleanups for the Renesas drivers.

separate independent devices. It also adds support for more devices on the
CompuLab cm-t335 and LogicPD Torpedo boards, and enables the new bindings
for qspi for am437x and dra7. There are also few dra7 regulator fixes, and
change of gpoi-key,wakeup to wakeup-source.
These depend on commit ae0add740c ("dmaengine: edma: DT: Change reserved

The UniPhier System Bus is an external bus that connects on-board
devices to the UniPhier SoC. Each bank (chip select) is dynamically
mapped to the CPU-viewed address base via the bus controller. The
bus controller must be configured before any access to the bus.
This driver parses the "ranges" property of the System Bus node and
initialized the bus controller. After the bus becomes ready, devices
below it are populated.
Note:
Each bank can be mapped anywhere in the supported address space;
there is nothing preventing us from assigning bank 0 on 0x42000000,
0x43000000, or anywhere as long as such region is not used by others.
So, the "ranges" is just one possible software configuration, which
does not seem to fit in device tree because device tree is a hardware
description language. However, of_translate_address() requires
"ranges" in every bus node between CPUs and device mapped on the CPU
address space. In other words, "ranges" properties must be statically
defined in device tree. After some discussion, I decided the dynamic
address reassignment by the driver is too bothersome. Instead, the
device tree should provide a reasonable translation setup that the OS
can rely on.

According to commit 2503a5ecd8
"ARM: 6201/1: RealView: Do not use outer_sync() on ARM11MPCore
boards with L220" Some PB11MPCore RealView core tiles have broken
outer_sync.
We got rid of the custom barriers from the machine by disabling
outer sync, but that was just for the boardfile case. We have
to be able to do the same in the device tree case.
Since __l2c_init() is cloning and copying the L2C vtable,
we pass an argument to this function to optionally numb
the outer sync operation if desired, before initializing
the cache.
After this we can set up the cache correctly on the RealView
PB11MPCore. This was tested on a PB11MPCore known to have the
issue. Before this, spurious crashes would occur if we try to
set up the cache properly, after this it boots rock solid.
