afafcdd3ff regulator: arizona: Add regulator specific device tree binding document
Subsystem specific bindings for the Arizona devices are being factored
out of the MFD binding document into separate documents for each
subsystem. This patch adds a binding document that covers the existing
regulator specific bindings.

567cf94dc7 powerpc/book3e-64/kexec: Enable SMP release
The SMP release mechanism for FSL book3e is different from when booting
with normal hardware.  In theory we could simulate the normal spin
table mechanism, but not at the addresses U-Boot put in the device tree
-- so there'd need to be even more communication between the kernel and
kexec to set that up.  Instead, kexec-tools will set a boolean property
linux,booted-from-kexec in the /chosen node.

3648dc6d27 NFC: st-nci: Add ese-present/uicc-present dts properties
In order to align with st21nfca, dts configuration properties
ese_present and uicc_present are made available in st-nci driver.

So far, in early development firmware, because
nci_nfcee_mode_set(DISABLE) was not supported we had to try to
enable it during the secure element discovery phase.

After several trials on commercial and qualified firmware it appears
that nci_nfcee_mode_set(ENABLE) and nci_nfcee_mode_set(DISABLE) are
properly supported.

Such feature also help us to eventually save some time (~5ms) when
only one secure element is connected.

1be5336bc7 dmaengine: edma: New device tree binding
With the old binding and driver architecture we had many issues:
No way to assign eDMA channels to event queues, thus not able to tune the
system by moving specific DMA channels to low/high priority servicing. We
moved the cyclic channels to high priority within the code, but that was
just a workaround to this issue.
Memcopy was fundamentally broken: even if the driver scanned the DT/devices
in the booted system for direct DMA users (which is not effective when the
events are going through a crossbar) and created a map of 'used' channels,
this information was not really usable. Since via dmaengien API the eDMA
driver will be called with _some_ channel number, we would try to request
this channel when any channel is requested for memcpy. By luck we got
channel which is not used by any device most of the time so things worked,
but if a device would have been using the given channel, but not requested
it, the memcpy channel would have been waiting for HW event.
The old code had the am33xx/am43xx DMA event router handling embedded. This
should have been done in a separate driver since it is not part of the
actual eDMA IP.
There were no way to 'lock' PaRAM slots to be used by the DSP for example
when booting with DT.
In DT boot the edma node used more than one hwmod which is not a good
practice and the kernel prints warning because of this.

With the new bindings and the changes in the driver we can:
- No regression with Legacy binding and non DT boot
- DMA channels can be assigned to any TC (to set priority)
- PaRAM slots can be reserved for other cores to use
- Dynamic power management for CC and TCs, if only TC0 is used all other TC
  can be powered down for example

The DMA event crossbar on AM33xx/AM43xx is different from the one found in
DRA7x family.
Instead of a single event crossbar it has 64 identical mux attached to each
eDMA event line. When the 0 event mux is selected, the default mapped event
is going to be routed to the corresponding eDMA event line. If different
mux is selected, then the selected event is going to be routed to the given
eDMA event.

e278fc71b2 mtd: fsmc_nand: Add BCH4 SW ECC support for SPEAr600
This patch adds support for 4-bit ECC BCH4 for the SPEAr600 SoC. This can
be used by boards equipped with a NAND chip that requires 4-bit ECC
strength. The SPEAr600 HW ECC only supports 1-bit ECC strength.

To enable SW BCH4, you need to specify this in your nand controller
DT node:

	nand-ecc-mode = "soft_bch";
	nand-ecc-strength = <4>;
	nand-ecc-step-size = <512>;

Tested on a custom SPEAr600 board.

f8085bbada mmc: dw_mmc-rockchip: dt-binding: Add tuning related things
Add ciu_drive, ciu_sample clocks and default-sample-phase. This will later
be used by tuning code.

We do not touch ciu_drive (and by extension define default-drive-phase).
Drive phase is mostly used to define minimum hold times, while one could
write some code to determine what phase meets the minimum hold time
(ex 10 degrees) this will not work with the current clock phase framework
(which floors angles, so we'll get 0 deg, and there's no way to know what
resolution the floors happen at). We assume that the default drive angles
set by the hardware are good enough.

64ebda3acd Merge tag 'arm/soc/for-4.4/rpi-dt-v2' of https://github.com/Broadcom/stblinux into next/dt
This pull request contains the DT changes for BCM2835 in 4.4.  It
pulls in clk/clk-bcm2835 (which Stephen Boyd has said would be stable)
because the DT changes to enable the clock driver need the driver
itself to be present. These changes include the following:

- Eric Anholt, moves the bcm2835 clock driver under bcm/ where it belongs with
  other Broadcom clock providers drivers, defines the binding for new clock
  driver, adds support for programming the BCM2835 audio domain, adds the DDC I2C
  controller to Device Tree, and finally migrates the Device Tree to use the new
  clock driver binding

- Lubomir Rintel adds support for the Raspberry Pi Model A+ and B revision 2, and
  remove the I2S controller which is non-existent on Raspberry Pi Model B

- Stefan Wahren adds an uart0 label for referencing the UART adapter

4a5705a9c2 bus: sunxi-rsb: Add Allwinner Reduced Serial Bus (RSB) controller bindings
Reduced Serial Bus is a proprietary 2-line push-pull serial bus supporting
multiple slave devices. It was developed by Allwinner, Inc. and used by
Allwinner and X-Powers, Inc. for their line of PMICs and other peripheral
ICs.

Recent Allwinner SoCs, starting with the A23, have an RSB controller. This
is used to talk to the PMIC, and later with the A80 and A83 platform, the
audio codec IC.

8e3c595214 mailbox/omap: Add ti,mbox-send-noirq quirk to fix AM33xx CPU Idle
The mailbox framework controls the transmission queue and requires
either its controller implementations or clients to run the state
machine for the Tx queue. The OMAP mailbox controller uses a Tx-ready
interrupt as the equivalent of a Tx-done interrupt to run this Tx
queue state-machine.

The WkupM3 processor on AM33xx and AM43xx SoCs is used to offload
certain PM tasks, like doing the necessary operations for Device
PM suspend/resume or for entering lower c-states during cpuidle.

The CPUIdle on AM33xx requires the messages to be sent without
having to trigger the Tx-ready interrupts, as the interrupt
would immediately terminate the CPUIdle operation. Support for
this has been added by introducing a DT quirk, "ti,mbox-send-noirq"
and using it to modify the normal OMAP mailbox controller behavior
on the sub-mailboxes used to communicate with the WkupM3 remote
processor. This also requires the wkup_m3_ipc driver to adjust
its mailbox usage logic to run the Tx state machine.

NOTE:
- AM43xx does not communicate with WkupM3 for CPU Idle, so is
  not affected by this behavior. But, it uses the same IPC driver
  for PM suspend/resume functionality, so requires the quirk as
  well, because of changes to the common wkup_m3_ipc driver.

a4d8e93c31 usb: patches for v4.4 merge window
This pull request is large with a total of 136 non-merge
 commits. Because of its size, we will only describe the big things in
 broad terms.
 
 Many will be happy to know that dwc3 is now almost twice as fast after
 some profiling and speed improvements. Also in dwc3, John Youn from
 Synopsys added support for their new DWC USB3.1 IP Core and the HAPS
 platform which can be used to validate it.
 
 A series of patches from Robert Baldyga cleaned up uses of
 ep->driver_data as a flag for "claimed endpoint" in favor of the new
 ep->claimed flag.
 
 Sudip Mukherjee fixed a ton of really old problems on the amd5536udc
 driver. That should make a few people happy.
 
 Heikki Krogerus worked on converting dwc3 to the unified device property
 interface.
 
 Together with these, there's a ton of non-critical fixes, typos and
 stuff like that.

d40325b437 drm/msm/mdp5: Avoid printing error messages for optional clocks
The current behavior is to try to get optional clocks and print a
dev_err message in case of failure. This looks rather confusing
and may increase with the amount of optional clocks.

We may need a cleaner way to handle per-device clocks but in the
meantime, let's reduce the amount of dev_err messages during the
probe.

50760cad9d ASoC: fsl-asoc-card: add AC'97 support
Add AC'97 support to fsl-asoc-card using generic
ASoC AC'97 CODEC.

The SSI controller will silently enable any TX
AC'97 slots that have their bits set in SLOTREQ
received from CODEC and then will redirect some
of playback samples there.

That's why it is important to make sure that
any of CODEC playback slots that can pull samples
are set to slots 3/4 (standard PCM playback slots).
Currently, this applies to S/PDIF slots as they
were seen to pull samples sometimes even with
S/PDIF output being disabled.

0dfc86b317 clk: qoriq: Move chip-specific knowledge into driver
The device tree should describe the chips (or chip-like subblocks) in
the system, but it generally does not describe individual registers --
it should identify, rather than describe, a programming interface.

This has not been the case with the QorIQ clockgen nodes.  The
knowledge of what each bit setting of CLKCnCSR means is encoded in
three places (binding, pll node, and mux node), and the last also needs
to know which options are valid on a particular chip.  All three of
these locations are considered stable ABI, making it difficult to fix
mistakes (of which I have found several), much less refactor the
abstraction to be able to address problems, limitations, or new chips.

Under the current binding, a pll clock specifier of 2 means that the
PLL is divided by 4 -- and the driver implements this, unless there
happen to be four clock-output-names rather than 3, in which case it
interprets it as PLL divided by 3.  This does not appear in the binding
documentation at all.  That hack is now considered stable ABI.

The current device tree nodes contain errors, such as saying that
T1040 can set a core clock to PLL/4 when only PLL and PLL/2 are options.
The current binding also ignores some restrictions on clock selection,
such as p5020's requirement that if a core uses the "wrong" PLL, that
PLL must be clocked lower than the "correct" PLL and be at most 80% of
the rated CPU frequency.

Possibly because of the lack of the ability to express such nuance in
the binding, some valid options are omitted from the device trees, such
as the ability on p4080 to run cores 0-3 from PLL3 and cores 4-7 from
PLL1 (again, only if they are at most 80% of rated CPU frequency).
This omission, combined with excessive caution in the cpufreq driver
(addressed in a subsequent patch), means that currently on a 1500 MHz
p4080 with typical PLL configuration, cpufreq can lower the frequency
to 1200 MHz on half the CPUs and do nothing on the others.  With this
patchset, all CPUs can be lowered to 1200 MHz on a rev2 p4080, and on a
rev3 p4080 half can be lowered to 750 MHz and the other half to 600
MHz.

The current binding only deals with CPU clocks.  To describe FMan in
the device tree, we need to describe its clock.  Some chips have
additional muxes that work like the CPU muxes, but are not described in
the device tree.  Others require inspecting the Reset Control Word to
determine which PLL is used.  Rather than continue to extend this mess,
replace it.  Have the driver bind to the chip-specific clockgen
compatible, and keep the detailed description of quirky chip variations
in the driver, where it can be easily fixed, refactored, and extended.

Older device trees will continue to work (including a workaround for
old ls1021a device trees that are missing compatible and reg in the
clockgen node, which even the old binding required).  The pll/mux
details in old device trees will be ignored, but "clocks" properties
pointing at the old nodes will still work, and be directed at the
corresponding new clock.

3686d3e7d6 clk: shmobile: Add new Renesas CPG/MSSR DT bindings
On Renesas ARM SoCs (SH/R-Mobile, R-Car, RZ), the CPG (Clock Pulse
Generator) and MSSR (Module Standby and Software Reset) blocks are
intimately connected, and share the same register block.

Hence it makes sense to describe these two blocks using a
single device node in DT, instead of using a hierarchical structure with
multiple nodes, using a mix of generic and SoC-specific bindings.

These new DT bindings are intended to replace the existing DT bindings
for CPG core clocks ("renesas,*-cpg-clocks", "renesas,cpg-div6-clock")
and module clocks ("renesas,*-mstp-clocks"), at least for new SoCs.

This will make it easier to add module reset support later, which is
currently not implemented, and difficult to achieve using the existing
bindings due to the intertwined register layout.

35780e860f i2c: davinci: Optimize clock generation on Keystone SoC
According to "KeyStone Architecture Inter-IC Control Bus User Guide", fixed
additive part of frequency divisors (referred as "d" in the code and datasheet)
always equals to 6, independent of module clock prescaler.

                         module clock frequency
master clock frequency = ----------------------
                         (ICCL + 6) + (ICCH + 6)

It was not the case with original Davinci IP. Introduce new compatible property
"ti,keystone-i2c", which triggers special handling in the driver.

Without this change Keystone-based systems (having 204.8MHz input clock) choose
prescaler 29 (PSC=28). Using d=5 in this case leads to bus bitrate ~353kHz
instead of requested 400kHz. After correction, assuming d=6 bus rate is ~392kHz.
This gives ~11% transfer rate increase.

b4c3fcb3c7 misc: sram: extend usage of reserved partitions
This change adds functionality to operate on reserved SRAM partitions
described in device tree file. Two partition properties are added,
"pool" and "export", the first one allows to share a specific partition
for usage by a kernel consumer in the same manner as it is done for
the whole SRAM device, and "export" property provides access to some
SRAM area from userspace over sysfs interface. Practically it is
possible to specify both properties for an SRAM partition, however
simultaneous access from a kernel consumer and from userspace is not
serialized, but still the combination may be useful for debugging
purpose.

The change opens the following scenarios of SRAM usage:
* updates in a particular SRAM area specified by offset and size are
  done by bootloader, then this information is utilized by the kernel,
* a particular SRAM area is rw accessed from userspace, the stored
  data is persistent on soft reboots,
* a device driver secures SRAM area for its purposes,
* etc.

Note, strictly speaking the added optional properties describe policy
of SRAM usage, rather than hardware, but here the policy mostly
resembles flash partitions in devicetree, which is undoubtedly
a very popular option but it does not describe hardware.

Currently msi-parent is used by a few bindings to describe the
relationship between a PCI root complex and a single MSI controller, but
this property does not have a generic binding document.

Additionally, msi-parent is insufficient to describe more complex
relationships between MSI controllers and devices under a root complex,
where devices may be able to target multiple MSI controllers, or where
MSI controllers use (non-probeable) sideband information to distinguish
devices.

This patch adds a generic binding for mapping PCI devices to MSI
controllers. This document covers msi-parent, and a new msi-map property
(specific to PCI*) which may be used to map devices (identified by their
Requester ID) to sideband data for each MSI controller that they may
target.

6f29d3b277 Input: gpio_keys_polled - add support for abs/rel axis
This changAdd support for EV_ABS / EV_REL events to the gpio-keys-polled driver.


The driver already allows specifying what type of events (key / rel / abs)
a button generates when pressed, but for rel / abs axis we also need to
specify which value this specific gpio represents.

One use case is digital joysticks / direction-pads which are hooked up to
gpio, in this case we've left and right buttons which we want to map to
EV_ABS, ABS_X and we want generate events for left with a value of -1 and
for right with a value of +1 (and similar for up / down and ABS_Y).

c0e44929b5 Documentation: dt: Update OMAP iommu bindings for DRA7 DSPs
The DSP processor sub-systems on DRA7xx have two MMU instances
each, one for the processor core and the other for an internal
EDMA block. These MMUs need an additional shared register to be
programmed in the DSP_SYSTEM sub-module to be enabled properly.

The OMAP IOMMU bindings is updated to account for this additional
syscon property required for these DSP IOMMU instances on DRA7xx
SoCs. A new compatible "ti,dra7-dsp-iommu" is also defined to
distinguish these devices specifically from other DRA7 IOMMU
devices.

An example of the DRA7 DSP IOMMU nodes is also added to the
document for clarity.

96ee19becc soc: ti: add firmware file name as part of the driver
Currently firmware file name is included in the DTS. This is not scalable
as user has to change the DTS if they need upgrade to a new firmware.
Instead, add the firmware file name in the driver itself. As long as there
is no API change, new firmware upgrade is easy and require no driver
change. User is expected to copy the firmware image to the file system
and add a sym link to the new firmware for doing an upgrade. Driver add
a array of firmware file names to search for the available firmware blobs.
This scheme also prepare the driver for future changes to API if ever
happens. In such case it is assumed that driver needs to change to
accommodate the new firmware and new firmware file name will get added to
the array.

Also update the DT document to remove the firmware attribute and add
description about firmware in the driver documentation.
