Here is the big USB and PHY driver update for 4.16-rc1.
Along with the normally expected XHCI, MUSB, and Gadget driver patches,
there are some PHY driver fixes, license cleanups, sysfs attribute
cleanups, usbip changes, and a raft of other smaller fixes and
additions.
Full details are in the shortlog.
All of these have been in the linux-next tree for a long time with no
reported issues.

Core changes:
- Disallow open drain and open source flags to be set
simultaneously. This doesn't make electrical sense, and would
the hardware actually respond to this setting, the result
would be short circuit.
- ACPI GPIO has a new core infrastructure for handling quirks.
The quirks are there to deal with broken ACPI tables centrally
instead of pushing the work to individual drivers. In the world
of BIOS writers, the ACPI tables are perfect. Until they find a
mistake in it. When such a mistake is found, we can patch it
with a quirk. It should never happen, the problem is that it
happens. So we accomodate for it.
- Several documentation updates.
- Revert the patch setting up initial direction state from
reading the device. This was causing bad things for drivers
that can't read status on all its pins. It is only affecting
debugfs information quality.
- Label descriptors with the device name if no explicit label is
passed in.
- Pave the ground for transitioning SPI and regulators to use
GPIO descriptors by implementing some quirks in the device tree
GPIO parsing code.
New drivers:
- New driver for the Access PCIe IDIO 24 family.
Other:
- Major refactorings and improvements to the GPIO mockup driver
used for test and verification.
- Moved the AXP209 driver over to pin control since it gained a
pin control back-end. These patches will appear (with the same
hashes) in the pin control pull request as well.
- Convert the onewire GPIO driver w1-gpio to use descriptors.
This is merged here since the W1 maintainers send very few
pull requests and he ACKed it.
- Start to clean up driver headers using <linux/gpio.h> to just
use <linux/gpio/driver.h> as appropriate.

This is mostly updates of the usual driver suspects: arcmsr,
scsi_debug, mpt3sas, lpfc, cxlflash, qla2xxx, aacraid, megaraid_sas,
hisi_sas. We also have a rework of the libsas hotplug handling to
make it more robust, a slew of 32 bit time conversions and fixes, and
a host of the usual minor updates and style changes. The biggest
potential for regressions is the libsas hotplug changes, but so far
they seem stable under testing.

Pull timer updates from Thomas Gleixner:
"The timer departement presents:
- A rather large rework of the hrtimer infrastructure which
introduces softirq based hrtimers to replace the spread of
hrtimer/tasklet combos which force the actual callback execution
into softirq context. The approach is completely different from the
initial implementation which you cursed at 10 years ago rightfully.
The softirq based timers have their own queues and there is no
nasty indirection and list reshuffling in the hard interrupt
anymore. This comes with conversion of some of the hrtimer/tasklet
users, the rest and the final removal of that horrible interface
will come towards the end of the merge window or go through the
relevant maintainer trees.
Note: The top commit merged the last minute bugfix for the 10 years
old CPU hotplug bug as I wanted to make sure that I fatfinger the
merge conflict resolution myself.

specially highlighted.
First, we have converted the MMC block device from using the legacy blk
interface into using the modern blkmq interface. Not only do we get all the
nice effects from using blkmq, but it also means that new fresh nice code
replaces old rusty code. Great news to everybody that cares about MMC/SD!
It should also be noted that converting to blkmq has not been trivial, mostly
because of that we have been carrying too much of MMC specific optimizations
for the I/O request path, rather than striving to move these to the generic blk
layer. Hopefully we won't be doing that mistake, ever again.
Special thanks to Adrian Hunter (Intel) and to Linus Walleij (Linaro), who both
have been working on this for quite some time!
Second, on top of the blkmq deployment, we have enabled full support the eMMC
command queuing feature, introduced in the eMMC v.5.1 spec. This also includes
an implementation of a host driver library, supporting the corresponding CQHCI
HW. Ideally, those controllers that supports CQHCI should only need some minor
adaptations to make this play.
So far the sdhci-pci driver for the Intel GLKs and the sdhci-of-arasan driver
used on Rockchip RK3399, have enabled support for eMMC command queueing.
Worth to highlight is also that, implementing the eMMC command queuing support
has been a collaborative effort, as several people from Codeaurora, Rockchip,
Intel and Linaro have been involved. However, the work has been driven by
Adrian Hunter (Intel).
In some shadow of the above, here are the rest of the highlights:
MMC core:
- Don't remove non-removable cards during system suspend
- Add a slot-gpio helper to check capability of GPIO WP detection
MMC host:
- sdhci: Cleanups and improvements of some wakeup related code
- sdhci-pci-arasan: New variant to support Arasan PCI HW with integrated phy
- sdhci-acpi: Avoid broken UHS transfer modes on Intel CHT
- sdhci-acpi: Add support for ACPI HID of AMD Controller with HS400
- sdhci_f_sdh30: Add ACPI support
- sdhci-esdhc-imx: Enable/disable clock at runtime suspend/resume
- sdhci-of-esdhc: A few minor fixes
- mmci: Add support for new STM32 variant
- renesas_sdhi: enable R-Car D3 (r8a77995) support

Pull MMC updates from Ulf Hansson:
"There are two major achievements for MMC in this release, which
deserves to be specially highlighted.
First, we have converted the MMC block device from using the legacy
blk interface into using the modern blkmq interface. Not only do we
get all the nice effects from using blkmq, but it also means that new
fresh nice code replaces old rusty code. Great news to everybody that
cares about MMC/SD!
It should also be noted that converting to blkmq has not been trivial,
mostly because of that we have been carrying too much of MMC specific
optimizations for the I/O request path, rather than striving to move
these to the generic blk layer. Hopefully we won't be doing that
mistake, ever again.
Special thanks to Adrian Hunter (Intel) and to Linus Walleij (Linaro),
who both have been working on this for quite some time!
Second, on top of the blkmq deployment, we have enabled full support
the eMMC command queuing feature, introduced in the eMMC v.5.1 spec.
This also includes an implementation of a host driver library,
supporting the corresponding CQHCI HW. Ideally, those controllers that
supports CQHCI should only need some minor adaptations to make this
play.
So far the sdhci-pci driver for the Intel GLKs and the sdhci-of-arasan
driver used on Rockchip RK3399, have enabled support for eMMC command
queueing.
Worth to highlight is also that, implementing the eMMC command queuing
support has been a collaborative effort, as several people from
Codeaurora, Rockchip, Intel and Linaro have been involved. However,
the work has been driven by Adrian Hunter (Intel).
In some shadow of the above, here are the rest of the highlights:
MMC core:
- Don't remove non-removable cards during system suspend
- Add a slot-gpio helper to check capability of GPIO WP detection
MMC host:
- sdhci: Cleanups and improvements of some wakeup related code
- sdhci-pci-arasan: New variant to support Arasan PCI HW with integrated phy
- sdhci-acpi: Avoid broken UHS transfer modes on Intel CHT
- sdhci-acpi: Add support for ACPI HID of AMD Controller with HS400
- sdhci_f_sdh30: Add ACPI support
- sdhci-esdhc-imx: Enable/disable clock at runtime suspend/resume
- sdhci-of-esdhc: A few minor fixes
- mmci: Add support for new STM32 variant
- renesas_sdhi: enable R-Car D3 (r8a77995) support

Pull power management updates from Rafael Wysocki:
"This includes some infrastructure changes in the PM core, mostly
related to integration between runtime PM and system-wide suspend and
hibernation, plus some driver changes depending on them and fixes for
issues in that area which have become quite apparent recently.
Also included are changes making more x86-based systems use the Low
Power Sleep S0 _DSM interface by default, which turned out to be
necessary to handle power button wakeups from suspend-to-idle on

On the cpufreq front we have fixes and cleanups in the core, some new
hardware support, driver updates and the removal of some unused code
from the CPU cooling thermal driver.

Some systems need to set regulators to specific states when they enter
low power modes, especially around CPUs. There are many of these modes
depending on the particular runtime state.
Currently the regulator consumers are not granted permission to change
suspend state of regulator devices, the constraints are configured at
startup. In order to allow changes in a vlotage range, we need to add
new properties for voltage range and a flag to give permission to
change the suspend voltage and suspend on/off in suspend mode.

Apologies for not being able to send this earlier but it took
me few revisions to get the smartreflex changes right and

DisplayPort.
Tegra DRM now also uses the atomic commit helpers instead of the open-
coded variant that was only doing half its job. As a bit of a byproduct
of the Tegra186 support the driver also gained HDMI 2.0 as well as zpos
property support.
Along the way there are also a few patches to clean up a few things and

On some x86 tablets with a silead touchscreen the windows logo on the
front is a capacitive home button. Touching this button results in a touch
with bits 12-15 of the Y coordinates set, while normally only the lower 12
are used.
Detect this and report a KEY_LEFTMETA press when this happens. Note for
now we only respond to the Y coordinate bits 12-15 containing 0x01, on some
tablets *without* a capacative button I've noticed these bits containing
0x04 when crossing the edges of the screen.

The DMIC DAI driver specifies a number of 1 to 8 channels for each DAI.
The actual number of mics can currently not be configured in the device
tree or audio glue, but is derived from the min/max channels of the CPU
and codec DAI. A typical CPU DAI has two or more channels, in consequence
a single mic is treated as a stereo/multi channel device, even though
only one channel carries audio data.
This change adds the option to specify the number of used DMIC channels
in the device tree. When specified this value overwrites the default
channels_max value of 8 in the snd_soc_dai_driver struct of the codec.
