Allow platform-code to disable the reset on probe and suspend/resume
by setting a "disable-reset" boolean device property on the device.
There are several reasons why the platform-code may want to disable
the reset on probe and suspend/resume:
1) Resetting the charger should never be necessary it should always have
sane values programmed. If it is running with invalid values while we
are not running (system turned off or suspended) there is a big problem
as that may lead to overcharging the battery.
2) The reset in suspend() is meant to put the charger back into default
mode, but this is not necessary and not a good idea. If the charger has
been programmed with a higher max charge_current / charge_voltage then
putting it back in default-mode will reset those to the safe power-on
defaults, leading to slower charging, or charging to a lower voltage
(and thus not using the full capacity) while suspended which is
undesirable. Reprogramming the max charge_current / charge_voltage
after the reset will not help here as that will put the charger back
in host mode and start the i2c watchdog if the host then does not do
anything for 40s (iow if we're suspended for more then 40s) the watchdog
expires resetting the device to default-mode, including resetting all
the registers to there safe power-on defaults. So the only way to keep
using custom charge settings while suspending is to keep the charger in
its normal running state with the i2c watchdog disabled. This is fine
as the charger will still automatically switch from constant current
to constant voltage and stop charging when the battery is full.
3) Besides never being necessary resetting the charger also causes
problems on systems where the charge voltage limit is set higher then the
reset value, if this is the case and the charger is reset while charging
and the battery voltage is between the 2 voltages, then about half the
time the charger gets confused and claims to be charging (REG08 contains
0x64) but in reality the charger has decoupled itself from VBUS (Q1 off)
and is drawing 0A from VBUS, leaving the system running from the battery.
This last problem is happening on a GPD-win mini PC with a bq24292i
charger chip combined with a max17047 fuel-gauge and a LiHV battery.
I've checked and TI does not list any errata for the bq24292i which

power: reset: Add a driver for the Gemini poweroff
The Gemini (SL3516) SoC has a special power controller block
that only deal with shutting down the system.
If you do not register a driver and activate the block, the
power button on the systems utilizing this SoC will do an
uncontrolled power cut, which is why it is important to have
a special poweroff driver.
The most basic functionality is to just shut down the system
by writing a special bit in the control register after the
system has reached pm_poweroff.
It also handles the poweroff from a button or other sources:
When the poweroff button is pressed, or a signal is sent to
poweroff from an infrared remote control, or when the RTC
fires a special alarm (!) the system emits an interrupt.
At this point, Linux must acknowledge the interrupt and
proceed to do an orderly shutdown of the system.
After adding this driver, pressing the poweroff button gives
this dmesg:
calling shutdown scripts..
setting /dev/rtc0 from system time
unmounting file systems...
umount: tmpfs busy - remounted read-only
umount: can't unmount /: Invalid argument

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

power: bq24190_charger: Check the interrupt status on resume
Some SoCs like omap3 can configure GPIO irqs to use Linux generic
dedicated wakeirq support. If the dedicated wakeirq is configured,
the SoC will use a always-on interrupt controller to produce wake-up
events.
If bq24190 is configured for dedicated wakeirq, we need to check the
interrupt status on PM runtime resume. This is because the Linux
generic wakeirq will call pm_runtime_resume() on the device on a
wakeirq. And as the bq24190 interrupt is falling edge sensitive
and only active for 250 us, there will be no device interrupt seen
by the runtime SoC IRQ controller.
Note that this can cause spurious interrupts on omap3 devices with
bq24190 connected to gpio banks 2 - 5 as there's a glitch on those
pins waking from off mode as listed in "Advisory 1.45". Devices
with this issue should not configure the optional wakeirq interrupt
in the dts file.

IB/device: Convert ib-comp-wq to be CPU-bound
This workqueue is used by our storage target mode ULPs
via the new CQ API. Recent observations when working
with very high-end flash storage devices reveal that
UNBOUND workqueue threads can migrate between cpu cores
and even numa nodes (although some numa locality is accounted
for).
While this attribute can be useful in some workloads,
it does not fit in very nicely with the normal
run-to-completion model we usually use in our target-mode
ULPs and the block-mq irq<->cpu affinity facilities.
The whole block-mq concept is that the completion will
land on the same cpu where the submission was performed.
The fact that our submitter thread is migrating cpus
can break this locality.
We assume that as a target mode ULP, we will serve multiple
initiators/clients and we can spread the load enough without
having to use unbound kworkers.
Also, while we're at it, expose this workqueue via sysfs which
is harmless and can be useful for debug.

infiniband: Fix alignment of mmap cookies to support VIPT caching
When vmalloc_user is used to create memory that is supposed to be mmap'd
to user space, it is necessary for the mmap cookie (eg the offset) to be
aligned to SHMLBA.
This creates a situation where all virtual mappings of the same physical
page share the same virtual cache index and guarantees VIPT coherence.
Otherwise the cache is non-coherent and the kernel will not see writes
by userspace when reading the shared page (or vice-versa).
