In its current form, the public headers of the mc-bus depend only on a
structure "dprc_obj_desc" defined in dprc.h. Move it to the bus public
header together with its associated defines and, in order to keep the
naming prefixes consistent rename it to "fsl_mc_obj_desc".
This will allow making dprc.h private in future patches.

When doing the following command:
# echo ":mod:kvm_intel" > /sys/kernel/tracing/stack_trace_filter
it triggered a crash.
This happened with the clean up of probes. It required all callers to the
regex function (doing ftrace filtering) to have ops->private be a pointer to
a trace_array. But for the stack tracer, that is not the case.
Allow for the ops->private to be NULL, and change the function command
callbacks to handle the trace_array pointer being NULL as well.

acpi_walk_resources will stop as soon as the callback passed in returns
an error status. On a x86 tablet I have the first GpioInt in the _AEI
resource list has no handler defined in the DSDT, causing
acpi_walk_resources to abort scanning the rest of the resource list,
which does define valid ACPI GPIO events.
This commit changes the return for not finding a handler from
AE_BAD_PARAMETER to AE_OK so that the rest of the resource list will
get scanned normally in case of missing event handlers.

The USB core and sysfs will attempt to enumerate certain parameters
which are unsupported by the au0828 - causing inconsistent behavior
and sometimes causing the chip to reset. Avoid making these calls.
This problem manifested as intermittent cases where the au8522 would
be reset on analog video startup, in particular when starting up ALSA
audio streaming in parallel - the sysfs entries created by
snd-usb-audio on streaming startup would result in unsupported control
messages being sent during tuning which would put the chip into an
unknown state.

In the i5000 and i5400 drivers, the NRECMEMB register is defined as a
16-bit value, which results in wrong shifts in the code, as reported by
sparse.
In the datasheets ([1], section 3.9.22.20 and [2], section 3.9.22.21),
this register is a 32-bit register. A u32 value for the register fixes
the wrong shifts warnings and matches the datasheet.
Also fix the mask to access to the CAS bits [27:16] in the i5000 driver.

genpd_syscore_switch() had two problems:
1. It silently assumed that device, it is being called for, belongs
to generic power domain and used container_of() on its power
domain pointer. Such assumption might not be true always.
2. It iterated over list of generic power domains without holding
gpd_list_lock mutex thus list could have been modified at the same
time.
Usage of genpd_lookup_dev() solves both problems as it is safe a call
for non-generic power domains and uses mutex when iterating.

the lock held time was non-deterministic due to cascading and long lasting

The rework of the timer wheel to the new non-cascading model removed also
the wheel traversals and the lock held times are deterministic now. This
allows to make the lock raw and thereby unbreaks NOHz* on preempt-RT.

Some Asus laptops (verified on X550VXK/FX502VD/FX502VE) get no
interrupts when pressing media keys thus the corresponding functions
are not invoked. It's due to the _GPE defines in DSDT for EC returns
differnt value compared to the GPE Number in ECDT. Confirmed with Asus
that the vale in ECDT is the correct one. This commit uses DMI quirks
to prevent calling _GPE when doing ec_parse_device() and keep the ECDT
GPE number setting for the EC device.
With previous commit, it is ensured that if there is an ECDT, it can
always be kept as boot_ec, this patch thus can implement a quirk on
top of the determined ECDT boot_ec.

We prepared _INI/_STA methods for \_SB, \_SB.PCI0, \_SB.LID0 and
\_SB.EC, _HID(PNP0C09)/_CRS/_GPE for \_SB.EC to poke Windows behavior
with qemu, we got the following execution sequence:
\_SB._INI
\_SB.PCI0._STA
\_SB.LID0._STA
\_SB.EC._STA
\_SB.PCI0._INI
\_SB.LID0._INI
\_SB.EC._INI
There is no extra DSDT EC device enumeration process occurring before
the main ACPI device enumeration process. That means acpi_ec_dsdt_probe()
is not Windows-compatible.
Tracking back, it was added by the following commit:
Commit: c5279dee26c0e8d7c4200993bfc4b540d2469598
Subject: ACPI: EC: Add some basic check for ECDT data
but that commit was misguided.
Why we shouldn't enumerate DSDT EC before the main ACPI device
enumeration?
The only way to know if the DSDT EC is valid would be to evaluate its
_STA control method, but it's not safe to evaluate this control method
that early and out of the ACPI enumeration process, because _STA may
refer to entities (such as resources or ACPI device objects) that may
not have been initialized before OSPM starts to enumerate them via
the main ACPI device enumeration.
But after we had reverted back to the expected behavior, a regression
was reported. On that platform, there is no ECDT, but the platform
control methods access EC operation region earlier than Linux expects
causing some ACPI method execution errors. For this reason, we just
go back to old behavior to still probe DSDT EC as the boot EC.
However, that turns out to lead to yet another functional breakage
and in order to work around all of the problems, we skip boot stage
DSDT probe when the ECDT exists so that a later quirk can always use
correct ECDT GPE setting.

It's reported that some buggy BIOS tables can contain 2 DSDT ECs, one of
them is invalid but acpi_ec_dsdt_probe() fails to pick the valid one.
This patch simply enhances sanity checks in ec_parse_device() as a
workaround to skip probing wrong namespace ECs.
