Default I2C device properties for Intel Broxton, especially SDA hold time
may not be enough on Intel Apollo Lake. These properties are used in case
we don't get timing parameters from ACPI.
The default SDA hold time for Broxton may fail with arbitration lost errors
on Apollo Lake:
i2c_designware i2c_designware.1: i2c_dw_handle_tx_abort: lost arbitration
Fix this by using different default device properties on Apollo Lake than
Broxton.

The Kconfig currently controlling compilation of this code is:
drivers/mfd/Kconfig:config TWL4030_CORE
drivers/mfd/Kconfig: bool "TI TWL4030/TWL5030/TWL6030/TPS659x0 Support"
...meaning that it currently is not being built as a module by anyone.
Lets remove what modular code that we can, so that when reading the
driver there is less doubt that it is builtin-only. Note that we can't
remove the twl_remove() itself ; it is still used by the probe unwind
routine. So we leave it linked into the .remove as well, even though
it will most likely never be called via that path from an unbind.
Since module_i2c_driver() uses the same init level priority as
builtin_i2c_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

probe_irq_off() returns '0' on failure, not NO_IRQ, so the check
in this driver is clearly wrong. This replaces it with the
regular '!irq' check used in other drivers.
The sa1100 platform that this driver is used on originally numbered
all its interrupts starting at '0', which would have conflicted with
this change, but as of commit 18f3aec ("ARM: 8230/1: sa1100: shift
IRQs by one"), this is not a problem any more.

As runtime PM doesn't function whilst processing system suspend/resume
operations and the Arizona IRQ handlers need runtime PM to function
we must disable IRQs during these operations. Whilst this is
already done in the driver we are using suspend/suspend_late and
resume/resume_noirq to do so which has two problems. Firstly, as
suspend_late is before suspend_noirq that means we still have a
small window where an IRQ can cause issues. Secondly, if another
suspend_late handler fails after ours has run then (as resume_noirq
will not run) we will make unbalanced calls to enable_irq.
This is all simply fixed by using the suspend_noirq callback rather
than suspend_late. Whilst we are doing this tidy the code up a little,
and use the appropriate helper macros.

There are some cases in arizona_dev_init, such as where we don't
recognise the chip ID, in which we head to the error path without
setting a sensible error code in ret. This would lead to the chip
silently failing probe, as it would still return 0. Fix this up by
adding appropriate sets of the return value.
Whilst adding these update the existing paths that do return an error
when the chip is not recognised to use ENODEV, which seems like a better
fit.

Member "status" of struct usb_sg_request is managed by usb core. A
spin lock is used to serialize the change of it. The driver could
check the value of req->status, but should avoid changing it without
the hold of the spinlock. Otherwise, it could cause race or error
in usb core.
This patch could be backported to stable kernels with version later
than v3.14.

The MSM8660, APQ8060, IPQ806x and MSM8960 have a GCC clock
to the message RAM used by the RPM. This needs to be enabled
for messages to pass through. This is a crude solution that
simply prepare/enable at probe() and disable/unprepare
at remove(). More elaborate PM is probably possible to
add later.
The construction uses IS_ERR() to gracefully handle the
platforms that do not provide a message RAM clock. It will
bail out of probe only if the clock is hitting a probe
deferral situation.
Of course this requires the proper device tree set-up:
rpm: rpm@104000 {
compatible = "qcom,rpm-msm8660";
clocks = <&gcc RPM_MSG_RAM_H_CLK>;
clock-names = "ram";
...
};
I have provided this in the MSM8660 device tree, and will
provide patches for the other targets.

Edge-rate:
As system and networking speeds increase, a signal's output transition,
also know as the edge rate or slew rate (V/ns), takes on greater importance
because high-speed signals come with a price. That price is an assortment of
interference problems like ringing on the line, signal overshoot and
undershoot, extended signal settling times, crosstalk noise, transmission
line reflections, false signal detection by the receiving device and
electromagnetic interference (EMI) -- all of which can negate the potential
gains designers are seeking when they try to increase system speeds through
the use of higher performance logic devices. The fact is, faster signaling
edge rates can cause a higher level of electrical noise or other type of
interference that can actually lead to slower line speeds and lower maximum
system frequencies. This parameter allow the board designers to change the
driving strange, and thereby change the EMI behavioral.
Edge-rate parameters (vddmac, edge-slowdown) get from Device Tree.
Tested on Beaglebone Black with VSC 8531 PHY.

Although rare, it's possible to hit PCI error early on device
probe, meaning possibly some structs are not entirely initialized,
and some might even be completely uninitialized, leading to NULL
pointer dereference.
The i40e driver currently presents a "bad" behavior if device hits
such early PCI error: firstly, the struct i40e_pf might not be
attached to pci_dev yet, leading to a NULL pointer dereference on
access to pf->state.
Even checking if the struct is NULL and avoiding the access in that
case isn't enough, since the driver cannot recover from PCI error
that early; in our experiments we saw multiple failures on kernel
log, like:
[549.664] i40e 0007:01:00.1: Initial pf_reset failed: -15
[549.664] i40e: probe of 0007:01:00.1 failed with error -15
[...]
[871.644] i40e 0007:01:00.1: The driver for the device stopped because the
device firmware failed to init. Try updating your NVM image.
[871.644] i40e: probe of 0007:01:00.1 failed with error -32
[...]
[872.516] i40e 0007:01:00.0: ARQ: Unknown event 0x0000 ignored
Between the first probe failure (error -15) and the second (error -32)
another PCI error happened due to the first bad probe. Also, driver
started to flood console with those ARQ event messages.
This patch will prevent these issues by allowing error recovery
mechanism to remove the failed device from the system instead of
trying to recover from early PCI errors during device probe.

40GbE Intel Wired LAN Driver Updates 2016-10-03
This series contains fixes to i40e only.
Stefan Assmann provides the changes in this series to resolve an issue
where when we run out of MSIx vectors, iWARP gets disabled automatically.
First adds a check for "no vectors left" during MSIx vector allocation
for VMDq, which will prevent more vectors being allocated than available.
Then fixed the MSIx vector redistribution when we reach the hardware limit
for vectors so that additional features like VMDq, iWARP, etc do not get
starved for vectors because the PF is hogging all the resources. Lastly,
fix the issue for flow director by moving the check for the reaching the
vector limit earlier in the code so that a decision can be made on
disabling flow director.

Adds a skeletal implementation of the qede RoCE driver -
The qedr has some dependencies of the state of the underlying base
interface. This adds some logic required with mutual registrations
and the ability to pass updates on 'intresting' events.

Other protocols beside the networking driver need the ability
of passing some L2 traffic, usually [although not limited] for the
purpose of some management traffic.

"Here is the big USB, and PHY, and extcon, patchsets for 4.9-rc1.
Full details are in the shortlog, but generally a lot of new hardware
support, usb gadget updates, and Wolfram's great cleanup of USB error
message handling, making the kernel image a tad bit smaller.
All of this has been in linux-next with no reported issues"

Pull tty and serial updates from Greg KH:
"Here is the big tty and serial patch set for 4.9-rc1.
It also includes some drivers/dma/ changes, as those were needed by
some serial drivers, and they were all acked by the DMA maintainer.
Also in here is the long-suffering ACPI SPCR patchset, which was
passed around from maintainer to maintainer like a hot-potato. Seems I
was the sucker^Wlucky one. All of those patches have been acked by the
various subsystem maintainers as well.

Pull CPU hotplug updates from Thomas Gleixner:
"Yet another batch of cpu hotplug core updates and conversions:
- Provide core infrastructure for multi instance drivers so the
drivers do not have to keep custom lists.
- Convert custom lists to the new infrastructure. The block-mq custom
list conversion comes through the block tree and makes the diffstat
tip over to more lines removed than added.
- Handle unbalanced hotplug enable/disable calls more gracefully.
- Remove the obsolete CPU_STARTING/DYING notifier support.
- Convert another batch of notifier users.
The relayfs changes which conflicted with the conversion have been
shipped to me by Andrew.
The remaining lot is targeted for 4.10 so that we finally can remove
the rest of the notifiers"
