The ks8851 SPI ethernet wasn't documented, but we documented the
optional regulator supply for it under the mll based ethernet
chip. Furthermore, that compatible string needed another 'l'. Fix
all of this and document the optional vdd-io and reset-gpios
properties.

Several cases of overlapping changes.
The xfrm6_output.c has a bug fix which overlaps the renaming
of skb->local_df to skb->ignore_df.
In the Altera TSE driver cases, the register access cleanups
in net-next overlapped with bug fixes done in net.
Similarly a bug fix to send ALB packets in the bonding driver using
the right source address overlaps with cleanups in net-next.

Some Ethernet MACs have a "fixed link", and are not connected to a
normal MDIO-managed PHY device. For those situations, a Device Tree
binding allows to describe a "fixed link" using a special PHY node.
This patch adds:
* A documentation for the fixed PHY Device Tree binding.
* An of_phy_is_fixed_link() function that an Ethernet driver can call
on its PHY phandle to find out whether it's a fixed link PHY or
not. It should typically be used to know if
of_phy_register_fixed_link() should be called.
* An of_phy_register_fixed_link() function that instantiates the
fixed PHY into the PHY subsystem, so that when the driver calls
of_phy_connect(), the PHY device associated to the OF node will be
found.
These two additional functions also support the old fixed-link Device
Tree binding used on PowerPC platforms, so that ultimately, the
network device drivers for those platforms could be converted to use
of_phy_is_fixed_link() and of_phy_register_fixed_link() instead of
of_phy_connect_fixed_link(), while keeping compatibility with their
respective Device Tree bindings.

net/sched/sch_api.c
The netlink conflict dealt with moving to netlink_capable() and
netlink_ns_capable() in the 'net' tree vs. supporting 'tc' operations
in non-init namespaces. These were simple transformations from
netlink_capable to netlink_ns_capable.
The Altera driver conflict was simply code removal overlapping some
void pointer cast cleanups in net-next.

The glue around the core designware IP is significantly different between
the Exynos and i.MX implementation, which is reflected in the DT bindings.
This changes the i.MX6 binding to reuse as much as possible from the common
designware binding and removes old cruft.
I removed the optional GPIOs with the following reasoning:
- disable-gpio: endpoint specific GPIO, not currently wired up in any code.
Should be handled by the PCI device driver, not the host controller
driver.
- wake-up-gpio: same as above.
- power-on-gpio: No user in any upstream DT. This should be handled by a
regulator which shouldn't be controlled by the host driver, but rather by
the PCI device driver.

The TI55231 appears to be fully compatible to the 5523 model from
National Semicondutor. This patch just adds DT bindings for it.

The non-DT driver allowed an active low property to be specified, but DT
is missing this in its description. Add the property to the DT binding
document, making it optional. It defaults to active high, which retains
compatibility with existing descriptions.
This should only be used for causes where the LED is wired to supply,
and the PWM does not sensibly support its own inversion.

Some oscillators can be turned off during off-idle saving few
a little bit power at the cost of the oscillator start up
latency.
If you board can do this, you can now enable it by using the
ti,twl4030-power-idle-osc-off compatible flag.

These settings are based on the "Recommended Sleep Sequences for
the Zoom Platform".
The settings assume most of the regulators are under control of
Linux, and twl4030 only cuts off VDD1 and VDD2 during off-idle as
Linux cannot do it.
For any board specific changes to these, let's patch them in as
changes to the generic data in the follow-up patches. This keeps
the board specific changes small.
Note that this does not consider the twl5030 errata 27 and 28.
That can be added later on after it has been tested. For more
information about errata 27 and 28.

The twl4030 PMIC needs to be configured properly for things like
warm reset and deeper idle states so the PMIC manages the regulators
properly based on the hardware triggers from the SoC. Earlier
we have configured twl4030 using platform data, but we want to
do it for device tree based booting also.
In some cases configuring twl4030 is needed for things to work.
For example, when rebooting an OMAP3530 at 125 MHz, it hangs.
With this patch, TWL4030 will be reset when a warm reset occures,
and OMAP3530 does not hang on reboot.
Let's add device tree support and configure things for warm reset
as the default when compatible = "ti,twl4030-power". More
complicated configurations can be added to the driver based on
other compatible flags.
Note we now also make the pdata const like it should be.
This allows use it for match->data with the device tree
related functions.
Based on earlier patch by Matthias Brugger <matthias.bgg@gmail.com>
and Lesly A M <leslyam@ti.com>.

This set of commits contains a couple of fixes to existing panel drivers
and support for some new panels.
One commit touches the DRM core in that in modifies the MIPI DSI support
to hook up the shutdown function so that drivers can provide code that's
run on shutdown. This is used by a subsequent commit to make the simple
panel driver power off the backlight on shutdown.

drm/tegra: Changes for v3.16-rc1
The majority of these changes are a slew of cleanups across the board.
A more noteworthy change is the addition of drm_dev_set_unique() and the
conversion of the Tegra DRM driver to use it. This allows us to get rid
of the host1x drm_bus implementation. Other USB and platform drivers can
be changed in a similar way. Unfortunately for most PCI devices there is
some userspace that relies on the old functionality and cannot be as
easily converted.
HDMI and hardware cursor support is added for Tegra124. The SOR output
gains support for exposing CRCs via debugfs, which can be used for
automated testing. Many values that were hardcoded in the SOR/eDP code
are now computed at runtime to increase compatibility with more devices.

The DSI controllers are powered by a (typically 1.2V) regulator. Usually
this is always on, so there was no need to support enabling or disabling
it thus far. But in order not to consume any power when DSI is inactive,
give the driver a chance to enable or disable the supply as needed.

Revert commit 18ebc0f404d5 "drm/tegra: hdmi: Enable VDD earlier for
hotplug/DDC" and instead add a new supply for the +5V pin on the HDMI
connector.
The vdd-supply property refers to the regulator that supplies the
AVDD_HDMI input on Tegra, rather than the +5V HDMI connector pin. This
was never a problem before, because all boards had that pin hooked up to
a regulator that was always on. Starting with Dalmore and continuing
with Venice2, the +5V pin is controllable via a GPIO. For reasons
unknown, the GPIO ended up as the controlling GPIO of the AVDD_HDMI
supply in the Dalmore and Venice2 DTS files. But that's not correct.
Instead, a separate supply must be introduced so that the +5V pin can be
controlled separately from the supplies that feed the HDMI block within
Tegra.
A new hdmi-supply property is introduced that takes the place of the
vdd-supply and vdd-supply is only enabled when HDMI is enabled rather
than all the time.

Exynos drm hdmi driver used to get dummy hdmiphy clock to
control the PMU bit for hdmiphy. This bit needs to be set
before setting any resolution to hdmi hardware. This was
handled using dummy hdmiphy clock which is removed here.
PMU is already defined as system controller for exynos
SoCs. Hdmi driver is modified to control the phy enable bit
inside PMU using regmap interfaces.
Devicetree binding document for hdmi is also updated.

Certain bridge chips use a GPIO to indicate the cable status instead
of the I_DP_HPD pin. This adds an optional device-tree property,
"samsung,hpd-gpio", to the exynos-dp controller which indicates that
the specified GPIO should be used for hotplug detection.
The GPIO is then set up as an edge-triggered interrupt where the
rising edge indicates hotplug-in and the falling edge indicates hotplug-out.

On Exynos5440 and Exynos5420 there are registers common
across the TMU channels.
To support that, we introduced a ADDRESS_MULTIPLE flag in the
driver and the 2nd set of register base and size are provided
in the "reg" property of the node.
As per Amit's suggestion, this patch changes the base_common
to base_second and SHARED_MEMORY to ADDRESS_MULTIPLE.

Support is added for the Broadcom Kona family of SoCs and the Intel
LPSS driver can now probe PCI devices in addition to ACPI devices.
Upon shutdown, the pwm-backlight driver will now power off the
backlight. It also uses the new descriptor-based GPIO API for more
concise GPIO handling.
A large chunk of these changes also converts platforms to use the
lookup mechanism rather than relying on the global number space to
reference PWM devices. This is largely in preparation for more
unification and cleanups in future patches. Eventually it will allow
the legacy PWM API to be removed"

Pull MTD updates from Brian Norris:
- refactor m25p80.c driver for use as a general SPI NOR framework for
other drivers which may speak to SPI NOR flash without providing full
SPI support (i.e., not part of drivers/spi/)
- new Freescale QuadSPI driver (utilizing new SPI NOR framework)
- updates for the STMicro "FSM" SPI NOR driver
- fix sync/flush behavior on mtd_blkdevs
- fixup subpage write support on a few NAND drivers
- correct the MTD OOB test for odd-sized OOB areas
- add BCH-16 support for OMAP NAND
- fix warnings and trivial refactoring
- utilize new ECC DT bindings in pxa3xx NAND driver
- new LPDDR NVM driver
- address a few assorted bugs caught by Coverity
- add new imx6sx support for GPMI NAND
- use a bounce buffer for NAND when non-DMA-able buffers are used
