Commit 52cf93e63ee6 ("HID: i2c-hid: Don't reset device upon system resume")
removes the need for the RESEND_REPORT_DESCR quirk for Raydium devices, but
kept it for the SIS device id 10FB touchscreens, as the author of that
commit could not determine if the quirk is still necessary there.
I've tested suspend/resume on a Toshiba Click Mini L9W-B which is the
device for which this quirk was added in the first place and with the
"Don't reset device upon system resume" fix the quirk is no longer
necessary, so this commit removes it.
Note even better I also had some other devices with SIS touchscreens which
suspend/resume issues, where the RESEND_REPORT_DESCR quirk did not help.
I've also tested these devices with the "Don't reset device upon system
resume" fix and I'm happy to report that that fix also fixes touchscreen
resume on the following devices:
Asus T100HA
Asus T200TA
Peaq C1010

This hantick HTIX5288 touchpad can quickly fall in a wrong state if
there are too many open/close operations. This will either make it stop
reporting any input, or will shift all the input reads by a few bytes,
making it impossible to decode.
Here, we never release the probed touchpad runtime pm while the driver
is loaded, which should disable all runtime pm suspend/resumes.
This fast repetition of sleep/wakeup is also more likely to happen when
using runtime PM, which is why the quirk is done there, and not for all
power downs, which would include suspend or module removal.

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.

The maximum globale report size has changed from 32->...->96->128 in the past
years. With the development usage of HID, the report_size max value 128 cannot
satisfy all requirements.
There are applications need to expose intrinsic metadata to camera stabilizing
applications such as 3DFE application. 3DFE intrinsic is designed to express
environmental information about sensor that may dynamically change while the
sensor is running (such data include noise spectral density, bias standard
deviation)
A sensor data field is SENSOR_VALUE_PAIR that consists of a PROPERTYKEY and
PROPVARIANT pair. It need to report a unique PROPERTYKEY for each data field.
Take “Noise Spectral Density” as an example, it report count will be
defined as below:
"Size of Property key GUID(16 Byte) + property key index(4 Byte) +
size of Noise Spectral Density value(4 Byte)"
In this case, the data report max is totally 192(24Byte), which is larger than
128, while max size 128 blocked it as illegal length. So increase the report
size to satisfy it and more demands in the future.

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.
