Currently, the i2c-hid driver does not call the suspend, resume, and
reset_resume callbacks in the hid_driver struct when those events occur.
This means that HID drivers for i2c-hid devices will not be able to execute
commands which may be needed during suspend or resume. One example is when a
touchpad using the hid-multitouch driver gets reset by i2c-hid coming out of
resume. Since the reset_resume callback never gets called the device is never
put back into the correct input mode. This patch calls the suspend and resume
callbacks and tries to duplicate the functionality of the usb-hid driver.

Reading the partial HID Descriptor is causing a firmware lockup in some
sensor hubs. Instead of a partial read, this patch implements the
i2c hid fetch using a fixed descriptor size (30 bytes) followed by a
verification of the BCDVersion (V01.00), and value stored in
wHIDDescLength (30 Bytes) for V1.00 descriptors.
As per i2c hid spec, this is the preferred model.
From hid-over-i2c-protocol-spec-v1-0:
There are a variety of ways a HOST may choose to retrieve
the HID Descriptor from the DEVICE. The following is a preferred
implementation but should not be considered the only implementation.
A HOST may read the entire HID Descriptor in a single read by
issuing a read for 30 Bytes to get the entire HID Descriptor
from the DEVICE.However, the HOST is responsible for validating that
1. The BCDVersion is V01.00 (later revisions may have different
descriptor lengths), and
2. The value stored in wHIDDescLength is 30 (Bytes) for V1.00
descriptors.

This patch refactors the way the thingm driver registers a blink(1) LED.
In order to make the driver simpler and more standard, drop the "rgb"
sysfs attribute and create one instance of LED class per RGB channel.
Actually, the name of the LED class instance registered for a blink(1)
device is "blink1::ABCD", where ABCD is the last 4 chars of the serial
number. The driver now registers 3 instances per RGB chip, named
"thingmX:{red,green,blue}:ledY" where X is the hidraw minor number and Y
is the RGB chip number (as seen by the firmware).
This patch also uses work queues to defer calls with the device, which
now allows triggers to work as expected with this LED device.
Also remove the brightness structure field and the brightness_get
backend, as it is already handled by the LED class, and changes the
prefix of functions and structures to thingm_ to match the driver name.

This driver add support for RMI4 over USB or I2C.
The current state is that it uses its own RMI4 implementation, but once
RMI4 is merged upstream, the driver will be a transport driver for the
RMI4 library.
Part of this driver should be considered as temporary. Most of the RMI4
processing and input handling will be deleted at some point.
I based my work on Andrew's regarding its port of RMI4 over HID (see
https://github.com/mightybigcar/synaptics-rmi4/tree/rmihid )
This repo presents how the driver may looks like at the end:
https://github.com/mightybigcar/synaptics-rmi4/blob/rmihid/drivers/input/rmi4/rmi_hid.c
Without this temporary solution, the workaround we gave to users
is to disable i2c-hid, which leads to disabling the touchscreen on the
XPS 11 and 12 (Haswell generation).

This way, hid_scan_report() gives the group MULTITOUCH to it, but
hid-multitouch can not handle it due to the constant collection ignored
by hid-input.
To prevent such crap in the future, and while we do not fix this particular
device, make the scan_report coherent with hid-input.c, and ignore constant
