Raydium touchscreen triggers interrupt storm after system-wide suspend:
[ 179.085033] i2c_hid i2c-CUST0000:00: i2c_hid_get_input: incomplete report (58/65535)
According to Raydium, Windows driver does not reset the device after system
resume.
The HID over I2C spec does specify a reset should be used at intialization, but
it doesn't specify if reset is required for system suspend.
Tested this patch on other i2c-hid touchpanels I have and those touchpanels do
work after S3 without doing reset. If any regression happens to other
touchpanel vendors, we can use quirk for Raydium devices.
There's still one device uses I2C_HID_QUIRK_RESEND_REPORT_DESCR so keep it
there.

Commit b0f847e16c1e ("HID: hid-sensor-hub: Force logical minimum to 1 for
power and report state") not only replaced the descriptor fixup done for
devices with the HID_SENSOR_HUB_ENUM_QUIRK with a generic fix, but also
accidentally removed the unrelated descriptor fixup for the Lenovo ThinkPad
Helix 2 sensor hub. This commit restores this fixup.
Restoring this fixup not only fixes the Lenovo ThinkPad Helix 2's sensors,
but also the Lenovo ThinkPad 8's sensors.

There is a NULL pointer dereference in case memory resources

Fix this by adding a new goto label and make the execution

commit f07b3c1da92d ("HID: generic: create one input report per
application type") was effectively the same as MULTI_INPUT:
hidinput->report was never set, so hidinput_match_application()
always returned null.
Fix that by testing against the real application.
Note that this breaks some old eGalax touchscreens that expect MULTI_INPUT
instead of HID_QUIRK_INPUT_PER_APP. Enable this quirk for backward
compatibility on all non-Win8 touchscreens.

When implementing commit 7f81c8db5489 ("HID: multitouch: simplify
the settings of the various features"), I wrongly removed a test
that made sure we never try to set the second InputMode feature
to something else than 0.
This broke badly some recent Elan panels that now forget to send the
click button in some area of the touchpad.

ish_dev_init() allocates 512*176 bytes memory for tx_buf and stores it at
&dev->wr_free_list_head.link list on ish_probe().
But there is no deallocation of this memory in ish_remove() and in
ish_probe() error path.
So current intel-ish-ipc provides 88 KB memory leak for each
probe/release.
The patch replaces kzalloc allocation by devm_kzalloc and removes
ishtp_device *dev deallocation by kfree.

On Mehlow Xeon-E workstation, ISH PCI device is enabled but without ISH
firmware. Here the ISH device PCI device id was reused for some non Linux
storage drivers. So this was not done for enabling ISH. But this has a
undesirable side effect for Linux.
Here the ISH driver will be loaded via PCI enumeration and will try to do
reset sequence. But reset sequence will wait till timeout as there is no
real ISH firmware is present to take action. This delay will add to boot
time of Linux (This platform will still continue to boot after this
timeout).
To avoid this boot delay we need to prevent loading of ISH drivers on
this platform. So we need to have hack to avoid treating this device as
ISH on this platform. To identify this workstation, we need some runtime
method. Luckily there are special PCI id on this workstation to
distinguish from the client version of this platform. On client version,
the ISH is supported using same PCI device id. So this change look for
the presence of PCI device IDs A309 and A30A and exit.

Usually, there is no palm rejection for touchscreens. You don't rest
your palm on the touchscreen while interacting with it.
However, some wacom devices do so because you can rest your palm while
interacting with the stylus.
Unfortunately, the spec for touchscreens[1] is less precise than the one
for touchpads[2]. This leads to a situation where it's 'legitimate'
for a touchscreen to provide both tipswitch off and confidence off in the
same report.
Work around that by keeping the slot active for one frame where we report
MT_TOOL_PALM, and then synthesizing the release event in a separate frame.

According to Microsoft specification [1] for Precision Touchpads (and
Touchscreens) the devices use "confidence" reports to signal accidental
touches, or contacts that are "too large to be a finger". Instead of
simply marking contact inactive in this case (which causes issues if
contact was originally proper and we lost confidence in it later, as
this results in accidental clicks, drags, etc), let's report such
contacts as MT_TOOL_PALM and let userspace decide what to do.

The tool works nicely with hid-generic, but it ends up creating 9
different input nodes with most of them only having ABS_MISC set.
Filter the axis out, which reduces the amount of devices to 2. One is
the proper System Multi-axis collection, the other exported device
seems to provide SLEEP and POWER Key, not sure how one can trigger
those events though.
Filtering the ABS_X and ABS_Y axes also prevents udev to detect this as
a touchscreen.

The Dell Canvas 27 has a tool that can be put on the surface and acts
as a dial. The firmware processes the detection of the tool and forward
regular HID reports with X, Y, Azimuth, rotation, width/height.
The firmware also exports Contact ID, Countact Count which may hint that
several totems can be used at the same time (the FW only supports one).
We can tell that MT_TOOL_DIAL will be reported by setting the min/max
of ABS_MT_TOOL_TYPE to MT_TOOL_DIAL.
This tool is aimed at being used by the system and not the applications,
so the user space processing should not go through the regular touch
inputs.
We set INPUT_PROP_DIRECT which applies ID_INPUT_TOUCHSCREEN to this new
type of devices, but we will counter this for the time being with the
special udev hwdb entry mentioned above.

The current way of handling multitouch data is not very straightforward:
- in mt_event() we do nothing
- in mt_report() we:
- do some gym to fetch the scantime and the contact count
- then iterate over the input fields where we copy the data to a
temporary place
- when we see the last field in a slot, we then use this data to emit
the input data
A more streamlined way is to first get all of the address in the report
of all fields, and then just pick the fields we are interested in in
mt_report()

Currently, hid-multitouch can only handle one multitouch collection at
a time. This is an issue for the Dell Canvas, as the Totem (a dial tool)
