We warn the user at driver probe time that debouncing is disabled.
However, if they request debouncing later on we print a confusing error
message:
gpio_aspeed 1e780000.gpio: Failed to convert 5000us to cycles at 0Hz: -524
Instead bail out when the clock is not present.

We need to initializes those variables to 0 for platforms that do not
provide ACPI parameters. Otherwise, we set sda_hold_time to random

Since v4.9 i2c-tiny-usb generates the below call trace
and longer works, since it can't communicate with the
USB device. The reason is, that since v4.9 the USB
stack checks, that the buffer it should transfer is DMA
capable. This was a requirement since v2.2 days, but it
usually worked nevertheless.

When TX checksum offload is used, if the computed checksum is 0 the
LAN95xx device do not alter the checksum to 0xffff. In the case of ipv4
UDP checksum, it indicates to receiver that no checksum is calculated.
Under ipv6, UDP checksum yields a result of zero must be changed to
0xffff. Hence disabling checksum offload for ipv6 packets.

For the sake of DT binding stability, this IIO driver is a child of an
MFD driver for Allwinner A10, A13 and A31 because there already exists a
DT binding for this IP. The MFD driver has a DT node but the IIO driver
does not.
The IIO device registers the temperature sensor in the thermal framework
using the DT node of the parent, the MFD device, so the thermal
framework could match the phandle to the MFD device in the DT and the
struct device used to register in the thermal framework.
devm_thermal_zone_of_sensor_register was previously used to register the
thermal sensor with the parent struct device of the IIO device,
representing the MFD device. By doing so, we registered actually the
parent in the devm routine and not the actual IIO device.
This lead to the devm unregister function not being called when the IIO
module driver is removed. It resulted in the thermal framework still
polling the get_temp function of the IIO module while the device doesn't
exist anymore, thus generated a kernel panic.
Use the non-devm function instead and do the unregister manually in the
remove function.

The register mapping for the IIO driver for the Liteon Light and Proximity
sensor LTR501 interrupt mode is interchanged (ALS/PS).
There is a register called INTERRUPT register (address 0x8F)
Bit 0 represents PS measurement trigger.
Bit 1 represents ALS measurement trigger.
This two bit fields are interchanged within the driver.

The third argument of devm_request_threaded_irq() is the primary
handler. It is called in hardirq context and checks whether the
interrupt is relevant to the device. If the primary handler returns
IRQ_WAKE_THREAD, the secondary handler (a.k.a. handler thread) is
scheduled to run in process context.
bcm_iproc_adc.c uses the secondary handler as the primary one
and the other way around. So this patch fixes the same, along with
re-naming the secondary handler and primary handler names properly.
Tested on the BCM9583XX iProc SoC based boards.

- a pull request from Christoph for NVMe, which ended up being
manually applied to avoid pulling in newer bits in master. Mostly
fibre channel fixes from James, but also a few fixes from Jon and
Vijay
- a pull request from Konrad, with just a single fix for xen-blkback

Rather than waiting for reset work thread to stop queues and abort the ios,
immediately stop the queues on error detection. Reset thread will restop
the queues (as it's called on other paths), but it does not appear to have

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson:
"We had a small batch of fixes before -rc1, but here is a larger one.
It contains a backmerge of 4.12-rc1 since some of the downstream
branches we merge had that as base; at the same time we already had
merged contents before -rc1 and rebase wasn't the right solution.
A mix of random smaller fixes and a few things worth pointing out:
- We've started telling people to avoid cross-tree shared branches if
all they're doing is picking up one or two DT-used constants from a
shared include file, and instead to use the numeric values on first
submission. Follow-up moving over to symbolic names are sent in
right after -rc1, i.e. here. It's only a few minor patches of this
type.
- Linus Walleij and others are resurrecting the 'Gemini' platform,
and wanted a cut-down platform-specific defconfig for it. So I
picked that up for them.
- Rob Herring ran 'savedefconfig' on arm64, it's a bit churny but it
helps people to prepare patches since it's a pain when defconfig
and current savedefconfig contents differs too much.
- Devicetree additions for some pinctrl drivers for Armada that were
merged this window. I'd have preferred to see those earlier but
it's not a huge deail.
The biggest change worth pointing out though since it's touching other
parts of the tree: We added prefixes to be used when cross-including
DT contents between arm64 and arm, allowing someone to #include
<arm/foo.dtsi> from arm64, and likewise. As part of that, we needed
arm/foo.dtsi to work on arm as well. The way I suggested this to Heiko
resulted in a recursive symlink.
Instead, I've now moved it out of arch/*/boot/dts/include, into a
shared location under scripts/dtc. While I was at it, I consolidated
so all architectures now behave the same way in this manner.
Rob Herring (DT maintainer) has acked it. I cc:d most other arch
maintainers but nobody seems to care much; it doesn't really affect
them since functionality is unchanged for them by default"

Commit bd698d24b1b57 ("i2c: designware: Get selected speed mode
sda-hold-time via ACPI") updated the logic that reads the timing
parameters for various I2C bus rates from the DSDT, to only read
the timing parameters for the currently selected mode.
This causes a WARN_ON() splat on platforms that legally omit the clock
frequency from the ACPI description, because in the new situation, the
core I2C designware driver still accesses the fields in the driver
struct that we no longer populate, and proceeds to calculate them from
the clock frequency. Since the clock frequency is unspecified, the
driver complains loudly using a WARN_ON().
So revert back to the old situation, where the struct fields for all
timings are populated, but retain the new logic which chooses the SDA
hold time from the timing mode that is currently in use.

During execlist_context_deferred_alloc() we presumed that the context is
uninitialised (we only just allocated the state object for it!) and
chose to optimise away the later call to engine->init_context() if
engine->init_context were NULL. This breaks with GVT's contexts that are
marked as pre-initialised to avoid us annoyingly calling
engine->init_context(). The fix is to not override ce->initialised if it
is already true.

The ICH9 is listed as having TCO v2, and indeed the behavior in the
datasheet corresponds to v2 (for example the NO_REBOOT flag is
accessible via the 16KiB-aligned Root Complex Base Address).
However, the TCO counts twice just like in v1; the documentation
of the SECOND_TO_STS bit says: "ICH9 sets this bit to 1 to indicate
that the TIMEOUT bit had been (or is currently) set and a second
timeout occurred before the TCO_RLD register was written. If this
bit is set and the NO_REBOOT config bit is 0, then the ICH9 will
reboot the system after the second timeout. The same can be found
in the BayTrail (Atom E3800) datasheet, and even HOWTOs around
the Internet say that it will reboot after _twice_ the specified
heartbeat.
I did not find the Apollo Lake datasheet, but because v4/v5 has
a SECOND_TO_STS bit just like the previous version I'm enabling
this for Apollo Lake as well.

USB-serial fixes for v4.12-rc2
Here's a fix for a long-standing issue in the ftdi_sio driver that
prevented unprivileged users from updating the low-latency flag,
something which became apparent after a recent change that restored the
older setting of not using low-latency mode by default.
A run of sparse revealed a couple of endianness issues that are now
fixed, and addressed is also a user-triggerable division-by-zero in
io_ti when debugging is enabled.
Finally there are some new device ids, including a simplification of how
we deal with a couple of older Olimex JTAG adapters.

OCTEON SoCs with CIU3 do not have interrupt masking local to the MMC
bus interface. Unfortunately, some even have a diagnostic register at
the same address of the enable register, which causes the interrupts
to fire immediately if stored to, thus breaking the driver. The proper
action on these SoCs is not to touch this register.
