drm/sun4i: Add compatible strings for A80 TCONs
The A80 has 2 or 3 TCONs. The documentation and vendor kernel are very
vague about the third TCON, to the point that it might not exist.

In the documentation, the first TCON is missing channel 1, and the
second is missing channel 0. However the vendor kernel seems to be
able to use them regardless. Here we model them like the old TCONs.

An oddity is that TCON0 requires the reset control for the eDP block
to be deasserted, for any register access to stick.

This patch adds compatible strings for TCON0 and TCON1, with TCON0
requiring an extra "edp" reset control.

Tony Lindgren 5d1ebbda03 phy: mapphone-mdm6600: Add USB PHY driver for MDM6600 on Droid 4
Let's add support for the GPIO controlled USB PHY on the MDM6600 modem.
It is used on some Motorola Mapphone series of phones and tablets such
as Droid 4.

The MDM6600 is hardwired to the first OHCI port in the Droid 4 case, and
is controlled by several GPIOs. The USB PHY is integrated into the MDM6600
device it seems. We know this as we get L3 errors from omap-usb-host if
trying to use the PHY before MDM6600 is configured.

The GPIOs controlling MDM6600 are used to power device on and off, to
configure the USB start-up mode (normal mode versus USB flashing), and
they also tell the state of the MDM6600 device.

The two start-up mode GPIOs are dual-purposed and used for out of band
(OOB) wake-up for USB and TS 27.010 serial mux. But we need to configure
the USB start-up mode first to get MDM6600 booted in the right mode to
be usable in the first place.

Note that the Motorola Mapphone Linux kernel tree has a "radio-ctrl"
driver for modems. But it really does not control the radio at all, it
just controls the modem power and start-up mode for USB. So I came to
the conclusion that we're better off having this done in the USB PHY
driver. For adding support for USB flashing mode, we can later on add
a kernel module option for flash_mode=1 or something similar.

Also note that currently there is no PM runtime support for the OHCI
on omap variant SoCs. So for low(er) power idle states, currenty both
ohci-platform and phy-mapphone-mdm6600 must be unloaded or unbound.

For reference here is what I measured for total power consumption on
an idle Droid 4 with and without USB related MDM6600 modules:

idle lcd off	phy-mapphone-mdm6600	ohci-platform
153mW		284mW			344mW

So it seems that MDM6600 is currently not yet idling even with it's
radio turned off, but that's something that is beyond the control of
this USB PHY driver. This patch does get us to the point where modem
data and GPS are usable with libqmi and ModemManager for example.
Voice calls need more audio driver work.

Christopher Bostic dd79873923 dt-bindings: fsi: Add optional property no-scan-on-init
Add an optional FSI master property 'no-scan-on-init.  This
can be specified to indicate that a master should not be
automatically scanned at init time.  This is required in cases
where a scan could interfere with another FSI master on the same
bus.

Jeremy Kerr 889ee9fe47 dt-bindings: fsi: Add specification for FSI busses
This change introduces a proposed layout for describing FSI busses in
the device tree. While the bus is probe-able, we'd still like a method
of describing subordinate (eg i2c) busses that are behind FSI devices.

The FSI core will be responsible for matching probed slaves & engines to
their device tree nodes, so the FSI device drivers' probe() functions
will be passed a struct device with the appropriate of_node populated
where a matching DT node is found.

Jeffy Chen 83fc580dcc Input: gpio-keys - add support for wakeup event action
Add support for specifying event actions to trigger wakeup when using
the gpio-keys input device as a wakeup source.

This would allow the device to configure when to wakeup the system. For
example a gpio-keys input device for pen insert, may only want to wakeup
the system when ejecting the pen.

For some new boards with hip07 chipset we are required to set PHY config

Gregory CLEMENT 3cd2c313f1 dmaengine: mv_xor_v2: Fix clock resource by adding a register clock
On the CP110 components which are present on the Armada 7K/8K SoC we need
to explicitly enable the clock for the registers. However it is not
needed for the AP8xx component, that's why this clock is optional.

With this patch both clock have now a name, but in order to be backward
compatible, the name of the first clock is not used. It allows to still
use this clock with a device tree using the old binding.

Chen-Yu Tsai 8591743f12 ARM: sunxi: mc-smp: Use DT enable-method for sun9i A80 SMP
Instead of having an early init function check the machine compatible
and installing multi-cluster SMP support for the A80 if it matches,
use a new cpu enable-method string. This makes the platform support
future proof in case anyone manages to add PSCI support.

The original init code for the SMP support is changed into the
.prepare_cpus callback in the smp_operations structure. Instead of
panicing when resources are missing like on some platforms, our code
merely guards against engaging SMP or CPU hotplug and returns an error.

ASoC: da7219: Add common clock usage for providing DAI clks
There is a need to use DA7219 as DAI clock master for other codecs
within a system, which means that the DAI clocks are required to
remain, regardless of whether the codec is actually running
playback/capture. To be able to expose control of the DAI clocking
the common clock framework has been employed.

The current implementation adds a simple clock gate for enabling
and disabling the DAI clocks, with no rate control supported
(this is still handled through standard hw_params() functions as
before). If DT is enabled then the clock is added to the OF
providers list, otherwise a clkdev lookup is used.

Arnd Bergmann f46f11dc1e ARM SCMI support for v4.17
ARM System Control and Management Interface(SCMI)[1] is more flexible and
 easily extensible than any of the existing interfaces.
 
 Few existing as well as future ARM platforms provide micro-controllers
 to abstract various power and other system management tasks which have
 similar interfaces, both in terms of the functions that are provided by
 them, and in terms of how requests are communicated to them.
 
 There are quite a few protocols like ARM SCPI, TI SCI, QCOM RPM, Nvidia Tegra
 BPMP, and so on already. This specification is to standardize and avoid any
 further fragmentation in the design of such interface by various vendors.
 
 The current SCMI driver implementation is very basic and initial support.
 It lacks support for notifications, asynchronous/delayed response, perf/power
 statistics region and sensor register region.
 
 Mailbox is the only form of transport supported currently in the driver.
 SCMI supports interrupt based mailbox communication, where, on completion
 of the processing of a message, the caller receives an interrupt as well as
 polling for completion.
 
 SCMI is designed to minimize the dependency on the mailbox/transport
 hardware. So in terms of SCMI, each channel in the mailbox includes
 memory area, doorbell and completion interrupt.
 
 However the doorbell and completion interrupt is highly mailbox dependent
 which was bit of controversial as part of SCMI/mailbox discussions.
 
 Arnd and me discussed about the few aspects of SCMI and the mailbox framework:
 
 1. Use of mailbox framework for doorbell type mailbox controller:
    - Such hardware may not require any data to be sent to signal the remote
      about the presence of a message. The channel will have in-built
      information on how to trigger the signal to the remote.
      There are few mailbox controller drivers which are purely doorbell based.
      e.g.QCOM IPC, STM, Tegra, ACPI PCC,..etc
 
 2. Supporting other mailbox controller:
    - SCMI just needs a mechanism to signal the remote firmware. Such
      controller may need fixed message to be sent to trigger a doorbell.
      In such case we may need to get that data from DT and pass the same
      to the controller. It's not covered in the current DT binding, but
      can be extended as optional property in future.
 
      However handling notifications may be interesting on such mailbox, but
      again there is no way to interpret what the data field(remote message)
      means, it could be a bit mask or a number or don't-care.
 
 Arnd mentioned that he doesn't like the way the mailbox binding deals
 with doorbell-type hardware, but we do have quite a few precedent drivers
 already and changing the binding to add a data field would not make it any
 better, but could cause other problems. So he is happy with the status quo
 of SCMI implementation.

ASoC: wm8524: Remove unit address
WM8524 does not use I2C nor SPI, hence no 'reg' property is used,
so remove the unit address from the bindings example to conform.

This avoids users getting dtc warnings when they copy the
binding example to a real dts file.

Add group configuration for uarts that are cut down
variants, the standard being full, i.e. all signals,
flow control, i.e. rx/tx and cts/rts, and rx/tx only.

This allows us to be more precise in which pins we're
actually using.

Unfortunately the existing naming scheme leaves things
to be desired, e.g. uart3grp0 means RX/TX and CTS/RTS,
yet uart0grp0 means all pins.
Since the exising suffixes have different meaning for
different uarts, and the fact that we cannot change
the name of existing groups, makes it hard to use a
descriptive name for the newly added groups.

Dave Gerlach afe761f8d3 soc: ti: Add pm33xx driver for basic suspend support
AM335x and AM437x support various low power modes as documented
in section 8.1.4.3 of the AM335x Technical Reference Manual and
section 6.4.3 of the AM437x Technical Reference Manual.

DeepSleep0 mode offers the lowest power mode with limited
wakeup sources without a system reboot and is mapped as
the suspend state in the kernel. In this state, MPU and
PER domains are turned off with the internal RAM held in
retention to facilitate the resume process. As part of
the boot process, the assembly code is copied over to OCMCRAM
so it can be executed to turn of the EMIF and put DDR into self
refresh.

Both platforms have a Cortex-M3 (WKUP_M3) which assists the MPU
in DeepSleep0 entry and exit. WKUP_M3 takes care
of the clockdomain and powerdomain transitions based on the
intended low power state. MPU needs to load the appropriate
WKUP_M3 binary onto the WKUP_M3 memory space before it can
leverage any of the PM features like DeepSleep. This loading
is handled by the remoteproc driver wkup_m3_rproc.

Communication with the WKUP_M3 is handled by a wkup_m3_ipc
driver that exposes the specific PM functionality to be used
the PM code.

In the current implementation when the suspend process
is initiated, MPU interrupts the WKUP_M3 to let it know about
the intent of entering DeepSleep0 and waits for an ACK. When
the ACK is received MPU continues with its suspend process
to suspend all the drivers and then jumps to assembly in
OCMC RAM. The assembly code puts the external RAM in self-refresh
mode, gates the MPU clock, and then finally executes the WFI
instruction. Execution of the WFI instruction with MPU clock gated
triggers another interrupt to the WKUP_M3 which then continues
with the power down sequence wherein the clockdomain and
powerdomain transition takes place. As part of the sleep sequence,
WKUP_M3 unmasks the interrupt lines for the wakeup sources. WFI
execution on WKUP_M3 causes the hardware to disable the main
oscillator of the SoC and from here system remains in sleep state
until a wake source brings the system into resume path.

When a wakeup event occurs, WKUP_M3 starts the power-up
sequence by switching on the power domains and finally
enabling the clock to MPU. Since the MPU gets powered down
as part of the sleep sequence in the resume path ROM code
starts executing. The ROM code detects a wakeup from sleep
and then jumps to the resume location in OCMC which was
populated in one of the IPC registers as part of the suspend
sequence.

Code is based on work by Vaibhav Bedia.

really no need for keeping the dedicated imx-wm8962 driver anymore.

Remove the imx-wm8962 machine driver.

Haiyue Wang be2ed207e3 ipmi: add an Aspeed KCS IPMI BMC driver
The KCS (Keyboard Controller Style) interface is used to perform in-band
IPMI communication between a server host and its BMC (BaseBoard Management
Controllers).

This driver exposes the KCS interface on ASpeed SOCs (AST2400 and AST2500)
as a character device. Such SOCs are commonly used as BMCs and this driver
implements the BMC side of the KCS interface.

* ms5611
  - Fix coding style in the probe function (whitespace)
* st_accel
  - Use strlcpy instead of strncpy to avoid potentially truncating a string.

ASoC: dmic: Add optional wakeup delay
On some systems a delay is needed after switching on the clocks, to allow
the output to stabilize and avoid a popping noise at the beginning of
the recording. Add the optional device tree property 'wakeup-delay-ms'
and apply the specified delay after enabling the mic. A blocking delay
can't be applied in dmic_daiops_trigger() since the function is called
in atomic context. Instead use a DAPM event handler to set the enable
GPIO and apply the delay in the handler.

dt-bindings: display: sun4i-drm: Add A83T HDMI pipeline
This commit adds all necessary compatibles and descriptions needed to
implement A83T HDMI pipeline.

Mixer is already properly described, so only compatible is added.

However, A83T TV TCON, which is connected to HDMI, doesn't have channel 0,
contrary to all TCONs currently described. Because of that, TCON
documentation is extended.

A83T features Synopsys DW HDMI controller with a custom PHY which looks
like Synopsys Gen2 PHY with few additions. Since there is no
documentation, needed properties were found out through experimentation
and reading BSP code.

At the end, example is added for newer SoCs, which feature DE2 and DW
HDMI.

Linus Torvalds ef991796be This is the bulk of pin control changes for the v4.16 kernel cycle:
Core changes:
 
 - After lengthy discussions and partly due to my ignorance, we have
   merged a patch making pinctrl_force_default() and pinctrl_force_sleep()
   reprogram the states into the hardware of any hogged pins, even
   if they are already in the desired state. This only apply to hogged
   pins since groups of pins owned by drivers need to be managed by
   each driver, lest they could not do things like runtime PM and
   put pins to sleeping state even if the system as a whole is not
   in sleep.
 
 New drivers:
 
 - New driver for the Microsemi Ocelot SoC. This is used in ethernet
   switches.
 
 - The X-Powers AXP209 GPIO driver was extended to also deal with pin
   control and moved over from the GPIO subsystem. This circuit is
   a mixed-mode integrated circuit which is part of AllWinner designs.
 
 - New subdriver for the Qualcomm MSM8998 SoC, core of a high end
   mobile devices (phones) chipset.
 
 - New subdriver for the ST Microelectronics STM32MP157 MPU and
   STM32F769 MCU from the STM32 family.
 
 - New subdriver for the MediaTek MT7622 SoC. This is used for routers,
   repeater, gateways and such network infrastructure.
 
 - New subdriver for the NXP (former Freescale) i.MX 6ULL. This SoC has
   multimedia features and target "smart devices", I guess in-car
   entertainment, in-flight entertainment, industrial control panels etc.
 
 General improvements:
 
 - Incremental improvements on the SH-PFC subdrivers for things like
   the CAN bus.
 
 - Enable the glitch filter on Baytrail GPIOs used for interrupts.
 
 - Proper handling of pins to GPIO ranges on the Semtec SX150X
 
 - An IRQ setup ordering fix on MCP23S08.
 
 - A good set of janitorial coding style fixes.

     pinctrl_force_sleep() reprogram the states into the hardware of any
     hogged pins, even if they are already in the desired state.

     This only apply to hogged pins since groups of pins owned by
     drivers need to be managed by each driver, lest they could not do
     things like runtime PM and put pins to sleeping state even if the
     system as a whole is not in sleep.

  New drivers:

   - New driver for the Microsemi Ocelot SoC. This is used in ethernet
     switches.

   - The X-Powers AXP209 GPIO driver was extended to also deal with pin
     control and moved over from the GPIO subsystem. This circuit is a
     mixed-mode integrated circuit which is part of AllWinner designs.

   - New subdriver for the Qualcomm MSM8998 SoC, core of a high end
     mobile devices (phones) chipset.

   - New subdriver for the ST Microelectronics STM32MP157 MPU and
     STM32F769 MCU from the STM32 family.

   - New subdriver for the MediaTek MT7622 SoC. This is used for
     routers, repeater, gateways and such network infrastructure.

   - New subdriver for the NXP (former Freescale) i.MX 6ULL. This SoC
     has multimedia features and target "smart devices", I guess in-car
     entertainment, in-flight entertainment, industrial control panels
     etc.

  General improvements:

   - Incremental improvements on the SH-PFC subdrivers for things like
     the CAN bus.

   - Enable the glitch filter on Baytrail GPIOs used for interrupts.

   - Proper handling of pins to GPIO ranges on the Semtec SX150X

   - An IRQ setup ordering fix on MCP23S08.

   - A good set of janitorial coding style fixes"

Linus Torvalds 3879ae653a The core framework has a handful of patches this time around, mostly due
to the clk rate protection support added by Jerome Brunet. This feature
 will allow consumers to lock in a certain rate on the output of a clk so
 that things like audio playback don't hear pops when the clk frequency
 changes due to shared parent clks changing rates. Currently the clk
 API doesn't guarantee the rate of a clk stays at the rate you request
 after clk_set_rate() is called, so this new API will allow drivers
 to express that requirement. Beyond this, the core got some debugfs
 pretty printing patches and a couple minor non-critical fixes.
 
 Looking outside of the core framework diff we have some new driver
 additions and the removal of a legacy TI clk driver. Both of these hit
 high in the dirstat. Also, the removal of the asm-generic/clkdev.h file
 causes small one-liners in all the architecture Kbuild files. Overall, the
 driver diff seems to be the normal stuff that comes all the time to
 fix little problems here and there and to support new hardware.
 
 Core:
  - Clk rate protection
  - Symbolic clk flags in debugfs output
  - Clk registration enabled clks while doing bookkeeping updates
 
 New Drivers:
  - Spreadtrum SC9860
  - HiSilicon hi3660 stub
  - Qualcomm A53 PLL, SPMI clkdiv, and MSM8916 APCS
  - Amlogic Meson-AXG
  - ASPEED BMC
 
 Removed Drivers:
  - TI OMAP 3xxx legacy clk (non-DT) support
  - asm*/clkdev.h got removed (not really a driver)
 
 Updates:
  - Renesas FDP1-0 module clock on R-Car M3-W
  - Renesas LVDS module clock on R-Car V3M
  - Misc fixes to pr_err() prints
  - Qualcomm MSM8916 audio fixes
  - Qualcomm IPQ8074 rounded out support for more peripherals
  - Qualcomm Alpha PLL variants
  - Divider code was using container_of() on bad pointers
  - Allwinner DE2 clks on H3
  - Amlogic minor data fixes and dropping of CLK_IGNORE_UNUSED
  - Mediatek clk driver compile test support
  - AT91 PMC clk suspend/resume restoration support
  - PLL issues fixed on si5351
  - Broadcom IProc PLL calculation updates

Linus Torvalds 537433b624 ARM: SoC device tree updates for 4.16
We get a moderate number of new machines this time, and only one
 new SoC variant (Actions S700):
 
 Actions:
   S700 Soc and CubieBoard7 development board
   Allo.com Sparky Single-board-computer
 
 Allwinner:
   Orange Pi R1 development board
   Libre Computer Board ALL-H3-CC H3 single-board computer
 
 ASpeed ast2x00:
    Witherspoon: OpenPower Power9 server manufactured by IBM that uses the ASPEED ast2500
    Zaius: OpenPower Power9 server manufactured by Invatech that uses the ASPEED ast2500
    Q71L: Intel Xeon server manufactured by Qanta that uses the ASPEED ast2400
 
 AT91:
   Axentia Nattis/Natte digital signage
   sama5d2 PTC-ek Evaluation board
 
 Freescale/NXP i.MX:
    SolidRun Humminboard2 development board
    Variscite DART-MX6 SoM and Carrier-board
    Technologic TS-4600 and TS-7970 development board
    Toradex Colibri iMX7D SoM board
    v1.5 variant of Solidrun Cubox-i and Hummingboard
 
 Freescale/NXP Layerscape:

   r8a7795 (M3-W) Salvator-XS board
 
 We finally managed to get the dtc warnings under control, with no more
 build-time warnings for bad device tree files. This includes fixes for
 the majority of platforms, including nomadik, samsung, lpc32xx, STi,
 spear, mediatek, freescale, qcom, realview, keystone, omap, kirkwood,
 renesas, hisilicon, and broadcom.
 
 Files get rearranged on a few platforms, in particular the Marvell
 Armada 7K/8K device tree files are changed in preparation for future
 SoC support, based on more than two of the same chips in one package,
 and some boards get renamed for oxnas for consistency.
 
 Finally, many existing SoCs gain descriptions for additional on-chip
 devices that we can now support with kernel drivers:
 
   Allwinner A83t (drm, ethernet, i2c, ...), H3/H5 (USB-OTG)
   Amlogic AXG family (clk, pinctrl, pwm, ...), and others (vpu, hdmi)
   Aspeed clk controller support

Linus Torvalds f6cff79f1d Char/Misc driver patches for 4.16-rc1
Here is the big pull request for char/misc drivers for 4.16-rc1.
 
 There's a lot of stuff in here.  Three new driver subsystems were added
 for various types of hardware busses:
 	- siox
 	- slimbus
 	- soundwire
 as well as a new vboxguest subsystem for the VirtualBox hypervisor
 drivers.
 
 There's also big updates from the FPGA subsystem, lots of Android binder
 fixes, the usual handful of hyper-v updates, and lots of other smaller
 driver updates.
 
 All of these have been in linux-next for a long time, with no reported
 issues.

Linus Torvalds 5d8515bc23 Staging/IIO patches for 4.16-rc1
Here is the big Staging and IIO driver patches for 4.16-rc1.
 
 There is the normal amount of new IIO drivers added, like all releases.
 
 The networking IPX and the ncpfs filesystem are moved into the staging
 tree, as they are on their way out of the kernel due to lack of use
 anymore.
 
 The visorbus subsystem finall has started moving out of the staging tree
 to the "real" part of the kernel, and the most and fsl-mc codebases are
 almost ready to move out, that will probably happen for 4.17-rc1 if all
 goes well.
 
 Other than that, there is a bunch of license header cleanups in the
 tree, along with the normal amount of coding style churn that we all
 know and love for this codebase.  I also got frustrated at the
 Meltdown/Spectre mess and took it out on the dgnc tty driver, deleting
 huge chunks of it that were never even being used.
 
 Full details of everything is in the shortlog.
 
 All of these patches have been in linux-next for a while with no
 reported issues.

Linus Torvalds e4ee8b85b7 USB/PHY updates for 4.16-rc1
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.

Linus Torvalds 9798f5178f The is the bulk of GPIO changes for the v4.16 kernel cycle.
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.
