Executing stmfts_power_on() function lasts over 2 seconds, what
significantly slows down the boot and resume processes if driver is
compiled in. Avoid this delay by forcing this driver to be probed
and suspended/resumed asynchronously.

If the device is unused and suspended, a call to open will cause the
device to autoresume through the call to usb_autopm_get_interface().
input_dev->users is already incremented by the input subsystem,
therefore this expression will always be evaluated to true:
if (input->users || usbtouch->type->irq_always)
result = usb_submit_urb(usbtouch->irq, GFP_NOIO);
The same URB will then be fail when resubmitted in usbtouch_open().
Introduce usbtouch->is_open to keep track of the state instead.

usb_autopm_get_interface() that is called in usbtouch_open() does an
autoresume if the device is suspended.
input_dev->mutex used in usbtouch_resume() is in this case already
taken by the input subsystem and will cause a deadlock.

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.

The interrupt is requested before the device is powered on and
it's value in some cases cannot be reliable. It happens on some
devices that an interrupt is generated as soon as requested
before having the chance to disable the irq.
Set the irq flag as IRQ_NOAUTOEN before requesting it.

Since AVR32 arch is gone, atmel-wm97xx driver is useless. In theory it

variant of the AC97C peripheral, so let's remove it.

MODULE_VERSION is useless for in-kernel drivers, so just remove all
usage of it in the touchscreen drivers. Along with this, some
DRV_VERSION macros were removed as they are also pointless.

We should not try to do any i2c transfers before the controller is
resumed (which happens before our resume method gets called).
So we need to disable our IRQ while suspended to enforce this. The
code paths for devices with GPIOs for the int and reset pins already
disable the IRQ the through goodix_free_irq().
This commit also disables the IRQ while suspended for devices without
GPIOs for the int and reset pins.
This fixes the i2c bus sometimes getting stuck after a suspend/resume
causing the touchscreen to sometimes not work after a suspend/resume.
This has been tested on a GPD pocked device.

On some x86 tablets with a silead touchscreen the windows logo on the
front is a capacitive home button. Touching this button results in a touch
with bits 12-15 of the Y coordinates set, while normally only the lower 12
are used.
Detect this and report a KEY_LEFTMETA press when this happens. Note for
now we only respond to the Y coordinate bits 12-15 containing 0x01, on some
tablets *without* a capacative button I've noticed these bits containing
0x04 when crossing the edges of the screen.

Pull driver core updates from Greg KH:
"Here is the set of "big" driver core patches for 4.16-rc1.
The majority of the work here is in the firmware subsystem, with
reworks to try to attempt to make the code easier to handle in the
long run, but no functional change. There's also some tree-wide sysfs
attribute fixups with lots of acks from the various subsystem
maintainers, as well as a handful of other normal fixes and changes.
And finally, some license cleanups for the driver core and sysfs code.
All have been in linux-next for a while with no reported issues"

Fix child node-lookup during probe, which ended up searching the whole
device tree depth-first starting at parent rather than just matching on
its children.
To make things worse, the parent node was prematurely freed, while the
child node was leaked.

gpiod_() API requires including "linux/gpio/consumer.h". Also, we are not
using the legacy API nor the static board files descriptions, so no need to
include gpio.h nor gpio/machine.h.

This is similar to commit a4b0a58bb142 ("Input: elan_i2c - do not
clobber interrupt trigger on x86")
On x86 we historically used falling edge interrupts in the driver
because that's how first Chrome devices were configured. They also
did not use ACPI to enumerate I2C devices (because back then there
was no kernel support for that), so trigger was hard-coded in the
driver. However the controller behavior is much more reliable if
we use level triggers, and that is how we configured ARM devices,
and how want to configure newer x86 devices as well. All newer
x86 boxes have their I2C devices enumerated in ACPI.
Let's see if platform code (ACPI, DT) described interrupt and
specified particular trigger type, and if so, let's use it instead
of always clobbering trigger with IRQF_TRIGGER_FALLING. We will
still use this trigger type as a fallback if platform code left
interrupt trigger unconfigured.

This changes all DEFINE_TIMER() callbacks to use a struct timer_list
pointer instead of unsigned long. Since the data argument has already been
removed, none of these callbacks are using their argument currently, so
this renames the argument to "unused".
