Table descriptors were being installed without properly formatting the
address using paddr_to_iopte, which does not match up with the
iopte_deref in __arm_lpae_map. This is incorrect for the LPAE pte
format, as it does not handle the high bits properly.
This was found on Apple T6000 DARTs, which require a new pte format
(different shift); adding support for that to
paddr_to_iopte/iopte_to_paddr caused it to break badly, as even <48-bit
addresses would end up incorrect in that case.

There is no need to call the dev_err() function directly to print a
custom message when handling an error from either the platform_get_irq()
or platform_get_irq_byname() functions as both are going to display an
appropriate error message in case of a failure.
This change is as per suggestions from Coccinelle, e.g.,
drivers/pci/controller/dwc/pcie-qcom-ep.c:556:2-9: line 556 is redundant because platform_get_irq() already prints an error

The write pointer in NVMe ZNS is invalid for a zone in zone state full.
The same also holds true for ZAC/ZBC.
The current behavior for NVMe is to simply propagate the wp reported by
the drive, even for full zones. Since the wp is invalid for a full zone,
the wp reported by the drive may be any value.
The way that the sd_zbc driver handles a full zone is to always report
the wp as zone start + zone len, regardless of what the drive reported.
null_blk also follows this convention.
Do the same for NVMe, so that a BLKREPORTZONE ioctl reports the write
pointer for a full zone in a consistent way, regardless of the interface
of the underlying zoned block device.
blkzone report before patch:
start: 0x000040000, len 0x040000, cap 0x03e000, wptr 0xfffffffffffbfff8
reset:0 non-seq:0, zcond:14(fu) [type: 2(SEQ_WRITE_REQUIRED)]
blkzone report after patch:
start: 0x000040000, len 0x040000, cap 0x03e000, wptr 0x040000 reset:0

The only fabrics target that supports metadata handling through the
separate integrity buffer is RDMA. It is currently usable only if the
size is 8B per block and formatted for protection information. If an
rdma target were to export a namespace with a different format (ex:
4k+64B), the driver will not be able to submit valid read/write commands
for that namespace.
Suppress setting the metadata feature in the namespace so that the
gendisk capacity will be set to 0. This will prevent read/write access
through the block stack, but will continue to allow ioctl passthrough
commands.

there are two bits in offset 8 for pulling the MIPI DPHY out of reset
and one of them needs to be set when IMX8MM_DISPBLK_PD_MIPI_CSI is brought
out of reset or the MIPI_CSI hangs.
Since MIPI_DSI is impacted, add the additional one for MIPI_DSI too.

Drivers that register a dax_dev should make sure it works, no need
to double check from the file system.

Replace the dax_host_hash with an xarray indexed by the pointer value
of the gendisk, and require explicitly calls from the block drivers that
want to associate their gendisk with a dax_device.

The device mapper DAX support is all hanging off a block device and thus
can't be used with device dax. Make it depend on CONFIG_FS_DAX instead
of CONFIG_DAX_DRIVER. This also means that bdev_dax_pgoff only needs to
be built under CONFIG_FS_DAX now.

Userspace tools like iio-sensor-proxy need to know the proximity level
that should be considered "near". This value is hardware-specific and
can be defined via the devicetree. Allow the driver to export the near
level.

Most AXPxxx-based reference designs place a 10k NTC thermistor on a
TS pin. When appropriately configured, AXP PMICs will inject fixed
current (80uA by default) into TS pin and measure the voltage across a
thermistor. The PMIC itself will by default compare this voltage with
predefined thresholds and disable battery charging whenever
the battery is too hot or too cold.
Alternatively, the TS pin can be configured as general-purpose
ADC input. This mode is not supported by the driver.
This patch allows reading the voltage on the TS pin. It can be then
either processed by userspace or used by kernel consumer like hwmon
ntc thermistor driver.

Introduce the capability to disable sensorhub through a device-tree
property since there are some configurations where users want to
explicitly disable sensor-hub auto-probing at bootstrap.
A typical configuration is when the sensorhub clock/data lines are connected
to a pull-up resistor since no slave sensors are connected to the i2c master.
If SDO/SA0 line is connected to the same pull-up resistor, when the driver
tries to probe slave devices connected on sensor-hub, it will force SDO/SA0
line to low, modifying the device i2c address.

ESL(Enhanced System Lockdown) was designed to lock PCI adapter firmware
images and prevent changes to critical non-volatile configuration data
so that uncontrolled, malicious or unintentional modification to the
adapters are avoided, ensuring it's operational state. Once this feature is
enabled, the device is locked, rejecting any modification to non-volatile
images. Once unlocked, the protection is off such that firmware and
non-volatile configurations may be altered.
Driver just reflects the capability and status of this through
the ethtool private flag.

This patch add some new qed APIs to query status block
info and report various data to MFW on tx timeout event
Along with that it enhances qede to dump more debug logs
(not just specific to the queue which was reported by stack)
on tx timeout which includes various other basic metadata about
all tx queues and other info (like status block etc.)
