HW requires the FID to be valid in order for the forward action to work.
So regardless of the current FID validity, just set the dummy FID which
would do the trick.

For forwarding using ACL action, HW needs a valid FID to be setup. It
does not actually use it, so it can be any valid FID. So create a dummy
FID only for this purpose.

xen-blkfron is the last users using rq->errros for passing back error to
blk-mq, and I'd like to get rid of that. In the longer run the driver
should be moving more of the completion processing into .complete, but
this is the minimal change to move forward for now.

This passes on the scsi_cmnd result field to users of passthrough

Note that the old IDE code abuses the errors field in very creative
ways and stores all kinds of different values in it. I didn't dare
to touch this magic, so the abuses are brought forward 1:1.

Currently it's used by the lighnvm passthrough ioctl, but we'd like to make
it private in preparation of block layer specific error code. Lighnvm already

We want our own clearly defined error field for NVMe passthrough commands,
and the request errors field is going away in its current form.
Just store the status and result field in the nvme_request field from
hardirq completion context (using a new helper) and then generate a
Linux errno for the block layer only when we actually need it.
Because we can't overload the status value with a negative error code
for cancelled command we now have a flags filed in struct nvme_request
that contains a bit for this condition.

MTD already allocates backing_dev_info dynamically. Convert it to use
generic infrastructure for this including proper refcounting. We drop
mtd->backing_dev_info as its only use was to pass mtd_bdi pointer from
one file into another and if we wanted to keep that in a clean way, we'd
have to make mtd hold and drop bdi reference as needed which seems
pointless for passing one global pointer...

I think this warning is a false complaint. mpt is only used when
mr_res_start_move_to() return zero, and in all such cases it initializes

Commit 4cfffcfa5106 ("irqchip/mips-gic: Fix local interrupts") fixed
local interrupts by creating virq mappings for them all at startup.
Unfortunately this change broke legacy IRQ controllers in the same
system, such as the i8259 on the Malta platform, as it allocates virq
numbers that were expected to be available for the legacy controller.
Instead of creating the mappings statically when the GIC is probed,
re-introduce the irq domain .map function, removed by commit e875bd66dfb
("irqchip/mips-gic: Fix local interrupts") and use it to set up the irq
handler and chip. Since a good deal of the required functionality is
already implemented by gic_irq_domain_alloc, repurpose that function for
gic_irq_domain_map and add a new gic_irq_domain_alloc which wraps
gic_irq_domain_map with the necessary conversion.
This change fixes the legacy interrupt controller of the Malta platform
without breaking the perf interrupt fixed by commit e875bd66dfb
("irqchip/mips-gic: Fix local interrupts").

In commit c98c1822ee13 ("irqchip/mips-gic: Add device hierarchy domain")
Qais indicates that he felt having a separate device IRQ domain was
cleaner, but along with everyone else I'm aware of touching this driver
I disagree.
Remove the separate device IRQ domain so that we simply have the main
GIC IRQ domain used for devices, and an IPI IRQ domain as a child. The
logic for handling the device interrupts & IPIs is cleanly separated
into the appropriate domain ops, making it much easier to reason about
what the driver is doing than the previous approach where the 2 child
domains had to call up to their parent, which had to handle both types
of interrupt & had all sorts of weird & wonderful duplication or
outright clobbering of setup performed by multiple domains.

Since commit 2af70a962070 ("irqchip/mips-gic: Add a IPI hierarchy
domain") introduced the GIC IPI IRQ domain we have tracked both
reservation of interrupts & their use with a single bitmap - ipi_resrv.
If an interrupt is reserved for use as an IPI but not actually in use
then the appropriate bit is set in ipi_resrv. If an interrupt is either
not reserved for use as an IPI or has been allocated as one then the
appropriate bit is clear in ipi_resrv.
Unfortunately this means that checking whether a bit is set in ipi_resrv
to prevent IPI interrupts being allocated for use with a device is
broken, because if the interrupt has been allocated as an IPI first then
its bit will be clear.
Fix this by separating the tracking of IPI reservation & usage,
introducing a separate ipi_available bitmap for the latter. This means
that ipi_resrv will now always have bits set corresponding to all
interrupts reserved for use as IPIs, whether or not they have been
allocated yet, and therefore that checking it when allocating device
interrupts works as expected.

Currently for DDR50 card, it need tuning in default. We meet tuning fail
issue for DDR50 card and some data CRC error when DDR50 sd card works.
This is because the default pad I/O drive strength can't make sure DDR50
card work stable. So increase the pad I/O drive strength for DDR50 card,
and use pins_100mhz.
This fixes DDR50 card support for IMX since DDR50 tuning was enabled from
commit 9faac7b95ea4 ("mmc: sdhci: enable tuning for DDR50")

The intel_pmic_xpower code provides an OPRegion handler, which must be
available before other drivers using it are loaded, which can only be
ensured if both the mfd and opregion drivers are built in, which is why
the Kconfig option for intel_pmic_xpower is a bool.
The use of IIO is causing trouble for generic distro configs here as
distros will typically want to build IIO drivers as modules and there
really is no reason to use IIO here. The reading of the ADC value is a
single regmap_bulk_read, which is already protected against races by
the regmap-lock.
This commit removes the use of IIO, allowing distros to enable the
driver without needing to built IIO in and also actually simplifies
the code.

Add opregion driver for Intel CHT Whiskey Cove PMIC, based on various
non upstreamed CHT Whiskey Cove PMIC patches. This does not include
support for the Thermal opregion (DPTF) due to lacking documentation.

It apears that devices designed around Wacom's G11 chipset (e.g. Lenovo
ThinkPad Yoga 260, Lenovo ThinkPad X1 Yoga, Dell XPS 12 9250, Dell Venue
8 Pro 5855, etc.) suffer from a common issue in their HID descriptors.
The logical maximum is not updated for the "Contact Identifier" usage,
leaving it as just "1" despite these devices being capable of tracking
far more touches.
Commit 60a221869803 began ignoring usages with out-of-range values,
causing problems for devices based on this chipset. Touches after
the first will have an out-of-range Contact Identifier, and ignoring
that usage will cause the kernel to incorrectly slot each finger's
events (along with all the knock-on userspace effects that entails).
This commit checks for these buggy descriptors and updates the maximum
where required. Prior chipsets have used "255" as the maximum (and the
G11, at least, doesn't seem to actually use IDs outside the range of
1..CONTACTMAX) so continue using this value.
