Pull LED fixes from Jacek Anaszewski:
"All three fixes are related to the newly added pattern trigger:
- remove mutex_lock() from timer callback, which would trigger
problems related to sleeping in atomic context, the removal is
harmless since mutex protection turned out to be redundant in this
case
- fix pattern parsing to properly handle intervals with brightness == 0
- fix typos in the ABI documentation"

Here is the big staging and IIO driver pull request for 4.20-rc1.
There are lots of things here, we ended up adding more lines than
removing, thanks to a large influx of Comedi National Instrument device
support. Someday soon we need to get comedi out of staging...
Other than the comedi drivers, the "big" things here are:
- new iio drivers
- delete dgnc driver (no one used it and no one had the hardware
anymore)
- vbox driver updates and fixes
- erofs fixes
- tons and tons of tiny checkpatch fixes for almost all staging
drivers
All of these have been in linux-next, with the last few happening a bit
"late" due to them getting stuck on my laptop during travel to the
Mantainers summit.
When merging with your tree, there will be 2 merge conflicts, both files
will be simple to resolve, just delete them :)

This patch adds a new LED trigger that LED device can configure
to employ software or hardware pattern engine.
Consumers can write 'pattern' file to enable the software pattern
which alters the brightness for the specified duration with one
software timer.
Moreover consumers can write 'hw_pattern' file to enable the hardware
pattern for some LED controllers which can autonomously control
brightness over time, according to some preprogrammed hardware
patterns.

The platform firmware "location" data is used to find port peer
relationships. But firmware is an unreliable source, and there are
real world examples of errors leading to missing or wrong peer
relationships. Debugging this is currently hard.
Exporting the location attribute makes it easier to spot mismatches
between the firmware data and the real world.

After commit 1cbd53c8cd ("usb: core: introduce per-port over-current
counters") usb ports expose a sysfs value 'over_current_count'
to user space. This value on its own is not very useful as it requires
manual polling.
As a solution, fire a udev event from the usb hub device that specifies
the values 'OVER_CURRENT_PORT' and 'OVER_CURRENT_COUNT' that indicate
the path of the usb port where the over-current event occurred and the
value of 'over_current_count' in sysfs. Additionally, call
sysfs_notify() so the sysfs value supports poll().

- Add bFrameIndex as a UVCG_FRAME_ATTR_RO for each frame size.
- Automatically assign ascending bFrameIndex to each frame in a format.
Before all "bFrameindex" attributes were set to "1" with no way to
configure the gadget otherwise. This resulted in the host always
negotiating for bFrameIndex 1 (i.e. the first frame size of the gadget).
After the negotiation the host driver will set the user or application
selected frame size, while the gadget is actually set to the first frame
size.
Now, when the containing format is linked into the streaming header,
iterate over all child frame descriptors and assign ascending indices.
The automatically assigned indices can be read from the new read only
bFrameIndex configfs attribute in each frame descriptor item.

The UVC format description are numbered using the descriptor's
bFormatIndex field. The index is used in UVC requests, and is thus
needed to handle requests in userspace. Make it dynamically discoverable
by exposing it in a bFormatIndex configfs attribute of the uncompressed
and mjpeg format config items.
The bFormatIndex value exposed through the attribute is stored in the
config item private data. However, that value is never set: the driver
instead computes the bFormatIndex value when linking the stream class
header in the configfs hierarchy and stores it directly in the class
descriptors in a separate structure. In order to expose the value
through the configfs attribute, store it in the config item private data
as well. This results in a small code simplification.

The video control and video streaming interface numbers are needed in
the UVC gadget userspace stack to reply to UVC requests. They are
hardcoded to fixed values at the moment, preventing configurations with
multiple functions.
To fix this, make them dynamically discoverable by userspace through
read-only configfs attributes in <function>/control/bInterfaceNumber and
<function>/streaming/bInterfaceNumber respectively.

Scrubbing pages on initial balloon down can take some time, especially
in nested virtualization case (nested EPT is slow). When HVM/PVH guest is
started with memory= significantly lower than maxmem=, all the extra
pages will be scrubbed before returning to Xen. But since most of them
weren't used at all at that point, Xen needs to populate them first
(from populate-on-demand pool). In nested virt case (Xen inside KVM)
this slows down the guest boot by 15-30s with just 1.5GB needed to be
returned to Xen.
Add runtime parameter to enable/disable it, to allow initially disabling
scrubbing, then enable it back during boot (for example in initramfs).
Such usage relies on assumption that a) most pages ballooned out during
initial boot weren't used at all, and b) even if they were, very few
secrets are in the guest at that time (before any serious userspace
kicks in).
Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also
enabled by default), controlling default value for the new runtime
switch.

The driver for Silead touchscreen configurations has been renamed
from silead_dmi to touchscreen_dmi since it starts supporting other
touchscreens which require some DMI quirks. At the same release cycle
it gets expanded to cover cases for Chuwi Vi10, ONDA V891W,
Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets.
Another bunch of changes is related to Mellanox platform code to allow
user space to communicate with Mellanox for system control and
monitoring purposes. The driver notifies user on hotplug device signal
receiving.
ASUS WMI drivers recognize lid flip action on UX360, and correctly
toggles airplane mode LED. In addition the keyboard backlight toggle
gets support.
ThinkPad ACPI driver enables support for calculator key (on at least P52).
It also has been fixed to support three characters model designators,
which are used for modern laptops. Earlier the battery, marked as BAT1,
on ThinkPad laptops has not been configured properly, which is fixed.
On the opposite the multi-battery configurations now probed correctly.
Dell SMBIOS driver starts working on some Dell servers which do not
support token interface. The regression with backlight detection has
also been fixed. In order to support dock mode on some laptops,
Intel virtual button driver has been fixed. The last but not least
is the fix to Intel HID driver due to changes in Dell systems that
prevented to use power button.

Pull x86 platform driver updates from Andy Shevchenko:
- The driver for Silead touchscreen configurations has been renamed
from silead_dmi to touchscreen_dmi since it starts supporting other
touchscreens which require some DMI quirks
It also gets expanded to cover cases for Chuwi Vi10, ONDA V891W,
Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets.
- Another bunch of changes is related to Mellanox platform code to
allow user space to communicate with Mellanox for system control and
monitoring purposes. The driver notifies user on hotplug device
signal receiving.
- ASUS WMI drivers recognize lid flip action on UX360, and correctly
toggles airplane mode LED. In addition the keyboard backlight toggle
gets support.
- ThinkPad ACPI driver enables support for calculator key (on at least
P52). It also has been fixed to support three characters model
designators, which are used for modern laptops. Earlier the battery,
marked as BAT1, on ThinkPad laptops has not been configured properly,
which is fixed. On the opposite the multi-battery configurations now
probed correctly.
- Dell SMBIOS driver starts working on some Dell servers which do not
support token interface. The regression with backlight detection has
also been fixed. In order to support dock mode on some laptops, Intel
virtual button driver has been fixed. The last but not least is the
fix to Intel HID driver due to changes in Dell systems that prevented
to use power button.

In this round, we've tuned f2fs to improve general performance by serializing
block allocation and enhancing discard flows like fstrim which avoids user IO
contention. And we've added fsync_mode=nobarrier which gives an option to user
where it skips issuing cache_flush commands to underlying flash storage. And
there are many bug fixes related to fuzzed images, revoked atomic writes, quota
ops, and minor direct IO.
Enhancement:
- add fsync_mode=nobarrier which bypasses cache_flush command
- enhance the discarding flow which avoids user IOs and issues in LBA order
- readahead some encrypted blocks during GC
- enable in-memory inode checksum to verify the blocks if F2FS_CHECK_FS is set
- enhance nat_bits behavior
- set -o discard by default
- set REQ_RAHEAD to bio in ->readpages
Bug fixes:
- fix a corner case to corrupt atomic_writes revoking flow
- revisit i_gc_rwsem to fix race conditions
- fix some dio behaviors captured by xfstests
- correct handling errors given by quota-related failures
- add many sanity check flows to avoid fuzz test failures
- add more error number propagation to their callers
- fix several corner cases to continue fault injection w/ shutdown loop

Here is the bit set of char/misc drivers for 4.19-rc1
There is a lot here, much more than normal, seems like everyone is
writing new driver subsystems these days... Anyway, major things here
are:
- new FSI driver subsystem, yet-another-powerpc low-level
hardware bus
- gnss, finally an in-kernel GPS subsystem to try to tame all of
the crazy out-of-tree drivers that have been floating around
for years, combined with some really hacky userspace
implementations. This is only for GNSS receivers, but you
have to start somewhere, and this is great to see.
Other than that, there are new slimbus drivers, new coresight drivers,
new fpga drivers, and loads of DT bindings for all of these and existing
drivers.
Full details of everything is in the shortlog.
All of these have been in linux-next for a while with no reported
issues.

Here are the big staging/iio patches for 4.19-rc1.
Lots of churn here, with tons of cleanups happening in staging drivers,
a removal of an old crypto driver that no one was using (skein), and the
addition of some new IIO drivers. Also added was a "gasket" driver from
Google that needs loads of work and the erofs filesystem.
Even with adding all of the new drivers and a new filesystem, we are
only adding about 1000 lines overall to the kernel linecount, which
shows just how much cleanup happened, and how big the unused crypto
driver was.
All of these have been in the linux-next tree for a while now with no
reported issues.
Note, you will have a merge problem with a device tree IIO file and the
MAINTAINERS file, both resolutions are easy, just take all changed.
There will be a skein file merge issue as well, but that file got
deleted so just drop that.
