Summary:
- Support for pipeline clock between KMS drivers.
. Exynos SoC is required to control clocks across KMS drivers
according to Exynos SoC version. So this patch refactos
some relevant codes and provides generic solution for it.
- Add Exynos5433 SoC support to HDMI parts - HDMI and DECON-TV.
- Add HW trigger mode support to CRTC drivers.
. In case of using i80 Panel, some Exynos SoC supports HW trigger
mode so this patch makes trigger mode - HW or SW trigger - to be
set according to SoC version properly.
- And some cleanups and regression fixups.

Armada 3700 SoC comprise a single XOR engine compliant with the ones used
in older Marvell SoC's like Armada XP or 38x. The only thing that needs
modification is the Mbus configuration, which has to be done on two
levels: global and in device. The first one is inherited from the
bootloader. The latter can be opened in a default way, leaving
arbitration to the bus controller. Hence filled mbus_dram_target_info
structure is not needed.
Patch "dmaengine: mv_xor: optimize performance by using a subset
of the XOR channels" introduced limitation for using XOR engines and
channels vs number of available CPU's. Those constraints do not however
fit Armada 3700 architecture with two possible CPU's and single,
dual-channel engine. Hence in this commit an adjustment for setting
maximum available channels is added.
This patch enables XOR access to DRAM by opening default window to 4GB
space with specific attribute.

There several changes are done here:
- Convert the property to be in bytes
Besides that this is a common practice for such property, the use of a value
in bytes much more convenient than handling the encoded one.
- Rename data_width to data-width in the device tree bindings
The change leaves the support for the old format as well just in case someone
will use a newer kernel with an old device tree blob.
- While here, replace dwc_fast_ffs() by __ffs()

Northstar is a family of SoCs used in home routers. They have USB 2.0
and 3.0 controllers with PHYs that need to be properly initialized.
This driver provides PHY init support in a generic way and can be bound
with an EHCI controller driver.
There are (just a few) registers being defined in bcma header. It's
because DMU/CRU registers will be also needed in other drivers. We will
need them e.g. in PCIe controller/PHY driver and at some point probably
in clock driver for BCM53573 chipset. By using include/linux/bcma/ we
avoid code duplication.

The XUSB pad controller allows PCIe lanes to be controlled individually,
providing fine-grained control over their power state. Previous attempts
at describing the XUSB pad controller in DT had erroneously assumed that
all PCIe lanes were driven by the same PHY, and hence the PCI host
controller would reference only a single PHY.
Moving to a representation of per-lane PHYs requires that the operating
system driver for the PCI host controller have access to the set of PHY
devices that make up the connection of each root port in order to power
up and down all of the lanes as necessary.

The NVIDIA Tegra XUSB pad controller provides a set of pads, each with a
set of lanes that are used for PCIe, SATA and USB.
A binding exists for the XUSB pad controller already, but it turned out
not to be flexible enough to describe all aspects of the controller. In
particular, the addition of XUSB support (for SuperSpeed USB) has shown
that the existing binding is no longer suitable. Mark the old binding
as deprecated and link to the new binding.

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and Gen 3. But beyond that its not clear what the
relationship between IP blocks might be. For example, I believe that
r8a7790 is older than r8a7791 but that doesn't imply that the latter is a
descendant of the former or vice versa.
We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.
For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.

Here's the big USB Gadget pull request. This time
not as large as usual with only 57 non-merge
commits.
The most important part here is, again, all the work
on dwc3. This time around we're treating all
endpoints (except for control endpoint) exactly the
same. They all have the same amount of TRBs on the
ring, they all treat the ring as an actual ring with
a link TRB pointing to the head, etc.
We're also helping the host side burst (on
SuperSpeed GEN1 or GEN2 at least) for as long as
possible until the endpoint returns NRDY.
Other than this big TRB ring rework on dwc3, we also
have a dwc3-omap DMA initialization fix, some extra
debugfs files to aid in some odd debug sessions and
a complete removal of our FIFO resizing logic.
We have a new quirk for some dwc3 P3 quirk in some
implementations.
The rest is basically non-critical fixes and the
usual cleanups.

recent regressions. Changes are across several platforms, so
I'm listing every change separately here.
Regressions since 4.5:
- A correction of the psci firmware DT binding, to prevent
users from relying on unintended semantics
- Actually getting the newly merged clock driver for some OMAP
platforms to work
- A revert of patches for the Qualcomm BAM, these need to be
reworked for 4.7 to avoid breaking boards other than the one
they were intended for
- A correction for the I2C device nodes on the Socionext Uniphier
platform
- i.MX SDHCI was broken for non-DT platforms due to a change
with the setting of the DMA mask
- A revert of a patch that accidentally added a nonexisting
clock on the Rensas "Porter" board
- A couple of OMAP fixes that are all related to suspend after
the power domain changes for dra7
- On Mediatek, revert part of the power domain initialization
changes that broke mt8173-evb
Fixes for older bugs:
- Workaround for an "external abort" in the omap34xx
suspend/resume code.
- The USB1/eSATA should not be listed as an excon device on
am57xx-beagle-x15 (broken since v4.0)
- A v4.5 regression in the TI AM33xx and AM43XX DT specifying
incorrect DMA request lines for the GPMC
- The jiffies calibration on Renesas platforms was incorrect
for some modern CPU cores.

* Aosong am2315 relative humidity
- new driver with triggered buffer support in follow up patch.
* bmi160 imu

* bmp280
- bmp180 support - note there is support in the misc/bmp085 driver. Intent
is to remove that driver long term.
* invensense mpu6050
- cleanup leading to explicit support of mpu9150 with a good few cleanups
along the way.
* Hope RF hp03 pressure and temperature sensor.

* maxim DS1803 potentiometer
- new driver
* maxim max44000 light and proximity sensor
- new driver built in a series of steps to support pretty much everything.
* ROHM BH1780 light sensor
- new driver. There is an existing driver in misc that this is pretty much
intended to replace. The discussion on whether to support the non standard
interface of that driver is some way is continuing.
* st-gyro
- lsm9ds0-gyro. The accel/magn side of this will take a while longer as
extensions to the st library are needed for cases where two types of sensor
share a single i2c address.
* ti-adc081c
- support the adc101c and adc121c
* Vishay VEML6070 UV sensor
- new driver.
New features
* core
- devm_ APIs for channel_get and channel_get_all. The first user of these
is the generic ADC based thermal driver. As it is going through the
thermal tree these will be picked up as a patch to that next cycle as that
is how the author preferred to do it.
- mounting matrix support. This new core support allows devices to provide
to userspace (typically from the device tree) allowing compensation for how
the sensor is mounted on the device. First examples are on UAVs but it
has a more mundane use on typical phone where the chip may be on the front
or the back of the circuit board and soldered at any angle. Includes
support for this ABI in ak8975 (which has an older interface, now
deprecated) and mpu6050.
* tools
- add a -a option to enable all available channels in generic_buffer sample.
Makes it somewhat easier to use.
* adis library and drivers
- support manual self test flag clearing. This has technically been broken
for a very long time - result is an offset on readings as the applied field
is on all the time.
* ak8975
- triggered buffer support
* bmc150
- spi support (including splitting the driver into core and i2c parts)
* bmp280
- oversampling support.
* dht11
- improved logging - useful to debug timing issues on this quirky device.
* st-sensors
- read each channel invidivually as not all support the optimization of
reading in bulk. This is technically a fix, but will need to be backported
if desired.
- support open drain and shared interrupts.
* ti-adc081c
- triggered buffer support.
Cleanups
* inkern
- white space fix.
* ad7606
- use the iio_device_claim_direct_mode call rather than open coding equiv.

* ms_sensors
- white space fix.
* mxs-lradc
- move current bindings out of staging - some will be shortly deprecated but
the reality is that we have device trees out there using them so they will
need to be supported for some time. They accidentally got left behind
when the driver graduated from staging.

Currently ARM CPUs DT bindings allows different enable-method value for
PSCI based systems. On ARM 64-bit this property is required and must be
"psci" while on ARM 32-bit systems this property is optional and must
be "arm,psci" if present.
However, "arm,psci" has always been the compatible string for the PSCI
node, and was never intended to be the enable-method. So this is a bug
in the binding and not a deliberate attempt at specifying 32-bit
differently.
This is problematic if 32-bit OS is run on 64-bit system which has
"psci" as enable-method rather than the expected "arm,psci".
So let's unify the value into "psci" and remove support for "arm,psci"
before it finds any users.

Add driver for the TCON (timing controller) module. The TCON module
is a separate module attached after the DCU (display controller
unit). Each DCU instance has its own, directly connected TCON
instance. The DCU's RGB and timing signals are passing through
the TCON module. TCON can provide timing signals for raw TFT panels
or operate in a bypass mode which leaves all signals unaltered.
The driver currently only supports the bypass mode.

interrupt for older SoCs (samsung,s5pv210-secss). However after

even clearing the hash interrupt bit.
Driver does not provide hash functions so it is safe to remove the hash
interrupt related code and to not require the interrupt in Device Tree.

Freescale has stated [1] that the LVDS clock source of the IMX6 does not
pass the PCI Gen2 clock jitter test, therefore unless an external Gen2
compliant external clock source is present and supplied back to the IMX6
PCIe core via LVDS CLK1/CLK2 you can not claim Gen2 compliance.
Add a DT property to specify Gen1 vs Gen2 and check this before allowing a
Gen2 link.
We default to Gen1 if the property is not present because at this time
there are no IMX6 boards in mainline that 'input' a clock on LVDS
CLK1/CLK2.
In order to be Gen2 compliant on IMX6 you need to:
- Have a Gen2 compliant external clock generator and route that clock back
to either LVDS CLK1 or LVDS CLK2 as an input (see IMX6SX-SabreSD
reference design).
- Specify this clock in the PCIe node in the DT (i.e.,
IMX6QDL_CLK_LVDS1_IN or IMX6QDL_CLK_LVDS2_IN instead of
IMX6QDL_CLK_LVDS1_GATE which configures it as a CLK output).

Currently the reset-gpio DT property which controls the PCI bus device
reset signal defaults to active-low reset sequence (L=reset state,
H=operation state) plus the code in reset function isn't GPIO polarity
aware - it doesn't matter if the defined reset-gpio is active-low or
active-high, it will always result into active-low reset sequence.
I've tried to fix it properly and change the reset-gpio reset sequence to
be polarity-aware, but this patch has been accepted and then reverted as it
has introduced few backward incompatible issues:
1. Some DTBs, for example, imx6qdl-sabresd, don't define reset-gpio
polarity correctly:
reset-gpio = <&gpio7 12 0>;
which means that it's defined as active-high, but in reality it's
active-low; thus it wouldn't work without a DTS fix.
2. The logic in the reset function is inverted:
gpio_set_value_cansleep(imx6_pcie->reset_gpio, 0)
msleep(100);
gpio_set_value_cansleep(imx6_pcie->reset_gpio, 1);
so even if some of the i.MX6 boards had reset-gpio polarity defined
correctly in their DTSes, they would stop working.
As we can't break old DTBs, we can't fix them, so we need to introduce this
new DT reset-gpio-active-high boolean property so we can support boards
with active-high reset sequence.
This active-high reset sequence is for example needed on Apalis SoMs, where
GPIO1_IO28, used to PCIe reset is not connected directly to PERST# PCIe
signal, but it's ORed with RESETBMCU coming off the PMIC, and thus is
inverted, active-high.
