Quite a quiet release for SPI, there are no changes at all to the core
and not that many changes to drivers. Highlights of those driver
changes include:
- SH MSIOF support for GPIO chip selects contributed by Geert
Uytterhoeven.
- Full duplex support for a3700 contributed by Maxime Chevallier.
- Support for DMA transfers on Atmel devices that require a bounce
buffer contributed by Radu Pirea.

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

Luis de Bethencourt).
- Make SPI domain validation (in the SCSI SPI transport driver) and
system-wide suspend mutually exclusive as they rely on the same
underlying mechanism and cannot be carried out at the same time
(Bart Van Assche).
- Fix the computation of the amount of memory to preallocate in the
hibernation core and clean up one function in there (Rainer Fiebig,

- Prepare the Operating Performance Points (OPP) framework for being
used with power domains and clean up one function in it (Viresh
Kumar, Wei Yongjun).
- Clean up the generic sysfs interface for device PM (Andy Shevchenko).
- Fix several minor issues in power management frameworks and clean
them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven,
Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker,

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
Surface Pro3.
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.
Apart from this, the Operating Performance Points (OPP) framework is
prepared to be used with power domains in the future and there is a
usual bunch of assorted fixes and cleanups.
Specifics:
- Define a PM driver flag allowing drivers to request that their
devices be left in suspend after system-wide transitions to the
working state if possible and add support for it to the PCI bus
type and the ACPI PM domain (Rafael Wysocki).

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.

The bulk of these changes are preparation work and addition of support
for Tegra186. Currently only HDMI output (the primary output on Jetson
TX2) is supported, but the hardware is also capable of doing DSI 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
fix minor issues.

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.

Merge tag 'imx-dt-4.16' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/dt
Pull "i.MX device tree changes for 4.16" from Shawn Guo:
- A few random updates for vf610-zii board: correct switch EEPROM size,
enable edma1, correct GPIO expander interrupt, add PHYs for switch2
device.
- LS1021A device tree updates: add reboot and QSPI device nodes, label
USB controllers, specify interrupt-affinity for PMU, fix TMR_FIPER1
setting, enable esdhc device, add Moxa UC-8410A board support.
- A bunch of patches from Fabio: fix reg - unit address mismatches,
remove leading zero in unit address, move regulators out of
simple-bus, move nodes with no reg property out of bus, remove extra
clock cell, add missing phy-cells to usb-nop-xceiv, etc.
- A couple series from Hummingboard developers: re-organise device tree
files for better handling various board versions, and then add the
new hummingboard2 board support on top of that.
- Disable AC'97 input pins pad and add support for powering off for
imx6qdl-udoo board.
- Convert from fbdev to drm bindings for imx6sx-sdb and imx6sl-evk
board.
- Add device tree for Variscite DART-MX6 SoM and Carrier-board support.
- Add new board support of TS-4600 and TS-7970 from Technologic
Systems.
- A series from Stefan to update imx7-colibri device tree and then add
new version of Toradex Colibri iMX7D board with eMMC support.
- Other random updates on various board support.
