Use touchscreen_properties structure instead of implementing all
properties by our own. It allows us to reuse generic code for parsing
device-tree properties (which was implemented manually in the driver for
now). Additionally, it allows us to report events using generic
touchscreen_report_pos(), which automatically handles inverted and
swapped axes.
This fixes the issue with the custom code incorrectly handling case where
ts->inverted_x and ts->swapped_x_y were true, but ts->inverted_y was
false. Assuming we have 720x1280 touch panel, ts->abs_x_max == 1279 and
ts->abs_y_max == 719 (because we inverted that in goodix_read_config()).
Now let's assume that we received event from (0:0) position (in touch
panel original coordinates). In function goodix_ts_report_touch() we
calculate input_x as 1279, but after swapping input_y takes that value
(which is more that maximum 719 value reported during initialization).
Note that since touchscreen coordinates are 0-indexed, we now report
touchscreen range as (0:size-1).
Developed and tested on custom DT-based device with gt1151 touch
panel.

Pull GPIO updates from Linus Walleij:
"The is the bulk of GPIO changes for the v4.16 kernel cycle. It is
pretty calm this time around I think. I even got time to get to things
like starting to clean up header includes.
Core changes:
- Disallow open drain and open source flags to be set simultaneously.
This doesn't make electrical sense, and would the hardware actually
respond to this setting, the result would be short circuit.
- ACPI GPIO has a new core infrastructure for handling quirks. The
quirks are there to deal with broken ACPI tables centrally instead
of pushing the work to individual drivers. In the world of BIOS
writers, the ACPI tables are perfect. Until they find a mistake in
it. When such a mistake is found, we can patch it with a quirk. It
should never happen, the problem is that it happens. So we
accomodate for it.
- Several documentation updates.
- Revert the patch setting up initial direction state from reading
the device. This was causing bad things for drivers that can't read
status on all its pins. It is only affecting debugfs information
quality.
- Label descriptors with the device name if no explicit label is
passed in.
- Pave the ground for transitioning SPI and regulators to use GPIO
descriptors by implementing some quirks in the device tree GPIO
parsing code.
New drivers:
- New driver for the Access PCIe IDIO 24 family.
Other:
- Major refactorings and improvements to the GPIO mockup driver used
for test and verification.
- Moved the AXP209 driver over to pin control since it gained a pin
control back-end. These patches will appear (with the same hashes)
in the pin control pull request as well.
- Convert the onewire GPIO driver w1-gpio to use descriptors. This is
merged here since the W1 maintainers send very few pull requests
and he ACKed it.
- Start to clean up driver headers using <linux/gpio.h> to just use
<linux/gpio/driver.h> as appropriate"

Pull dma mapping updates from Christoph Hellwig:
"Except for a runtime warning fix from Christian this is all about
consolidation of the generic no-IOMMU code, a well as the glue code
for swiotlb.
All the code is based on the x86 implementation with hooks to allow
all architectures that aren't cache coherent to use it.
The x86 conversion itself has been deferred because the x86
maintainers were a little busy in the last months"

Pull SCSI updates from James Bottomley:
"This is mostly updates of the usual driver suspects: arcmsr,
scsi_debug, mpt3sas, lpfc, cxlflash, qla2xxx, aacraid, megaraid_sas,
hisi_sas.
We also have a rework of the libsas hotplug handling to make it more
robust, a slew of 32 bit time conversions and fixes, and a host of the
usual minor updates and style changes. The biggest potential for
regressions is the libsas hotplug changes, but so far they seem stable
under testing"

Missing prefix 'pn' in MODULE_ALIAS lines causes the module to
not load automatically. The driver should use MODULE_DEVICE_TABLE
together with existing mlxplat_dmi_table instead.

Pull device mapper updates from Mike Snitzer:
- DM core fixes to ensure that bio submission follows a depth-first
tree walk; this is critical to allow forward progress without the
need to use the bioset's BIOSET_NEED_RESCUER.
- Remove DM core's BIOSET_NEED_RESCUER based dm_offload infrastructure.
- DM core cleanups and improvements to make bio-based DM more efficient
(e.g. reduced memory footprint as well leveraging per-bio-data more).
- Introduce new bio-based mode (DM_TYPE_NVME_BIO_BASED) that leverages
the more direct IO submission path in the block layer; this mode is
used by DM multipath and also optimizes targets like DM thin-pool
that stack directly on NVMe data device.
- DM multipath improvements to factor out legacy SCSI-only (e.g.
scsi_dh) code paths to allow for more optimized support for NVMe
multipath.
- A fix for DM multipath path selectors (service-time and queue-length)
to select paths in a more balanced way; largely academic but doesn't
hurt.
- Numerous DM raid target fixes and improvements.
- Add a new DM "unstriped" target that enables Intel to workaround
firmware limitations in some NVMe drives that are striped internally
(this target also works when stacked above the DM "striped" target).
- Various Documentation fixes and improvements.
- Misc cleanups and fixes across various DM infrastructure and targets
(e.g. bufio, flakey, log-writes, snapshot).

Add definitions for hotplug device masks and events offsets, in order to
specify explicitly all hardware registers allowed for IO operations for
all the drivers sharing register map with mlx-platform.
Extend register map configuration with the sets of writable, readable and
volatile registers to allow verification prior to the access. It prevents
unexpected access to hardware registers by the drivers, sharing register
map with mlx-platform.
Extend register map configuration with cache type field in order to have
ability to cache hardware register value, where possible. Use simple flat
array type for register lookups, which is most suitable in case when the
number of the registers is not too large.
Add at the end of probing routine calls to regcache_mark_dirty and
regcache_sync in order to sync register cache with hardware values. The
first routine indicate that hardware registers value required sync, the
second performs sync.
