UHID_INPUT2:

HID: multitouch: remove registered devices with default behavior
The default multitouch protocol class in use since the kernel v3.9 is
working quite well. Since its inclusion, the only devices we had to tweak
were those who really need quirks (GeneralTouch, FocalTech and Wistron,
the 3 of them are Win 7 certified ones).
The flow of new unhandled devices has stopped, which is great and I think
it's time to reduce the list of registered device.
This commit removes only the registration in the kernel of devices that
use the class MT_CLS_DEFAULT, or that can use it. By that, I mean that I
checked all the recordings I have, and the produced input device and
events are the same before and after applying the patch.
This gives two benefits:
- remove a bunch of lines of codes
- prevent bad handling of existing registered devices which are using a
different protocol while using the same VID/PID (I got the case of a
Quanta 3008 recently).
I also removed the associated classes (MT_CLS*). I kept their #define in
case people use the new_id sysfs node with a non standard class (their
should be really few people now, but we never now). This is why there
are /* reserved .... */.
Last, I add a comment on top of mt_devices[] definition to remember people
(and myself) not to include devices for the beauty of it.
To people still trying to add devices with the default class:
"""
Guys, try out your device under a kernel greater or equal to v3.9. If it
works, you are all set. Adding your VID/PID to the kernel only brings us
overload and you won't get anything from it _because_ even a backport of
this shiny patch will _not_ make the device work under 3.0, 3.2, 3.4 or
even 3.8.
So if it works, it works.
If it does not work, then yes, submit a patch or call for help.
In any cases, if you want me to do regression tests, I'd be happy to
get some traces of your device. But I won't patch the kernel if it works.

During device removal hid_disconnect() is called via hid_hw_stop() to
stop the device and free all its resources, including the sysfs
files. The problem is that if a user space process, such as upowerd,
holds a reference to a hidraw file the corresponding sysfs files will
be kept around (drop_ref() does not call device_destroy() if the open
counter is not 0) and it will be usb_disconnect() who, by calling
device_del() for the USB device, will indirectly remove the sysfs
files of the hidraw device (sysfs_remove_dir() is recursive these
days). Because of this, by the time user space releases the last
reference to the hidraw file and drop_ref() tries to destroy the
device the sysfs files are already gone and the kernel will print
the warning above.
Fix this by calling device_destroy() at USB disconnect time.

HID: add hid-cp2112 driver
This patch adds support for the Silicon Labs CP2112 "Single-Chip HID USB to
SMBus Master Bridge."
This is a HID device driver which registers as an i2c adapter and gpiochip to
expose these functions of the CP2112. The customizable USB descriptor fields
are exposed as sysfs attributes. The SMBus byte-read, byte-data-read/write,
and word-data-read transfer modes have been tested by talking to an i2c
sensor. The GPIO functions and USB descriptor field programming have also
been tested.

HID: Bluetooth: hidp: make sure input buffers are big enough
HID core expects the input buffers to be at least of size 4096
(HID_MAX_BUFFER_SIZE). Other sizes will result in buffer-overflows if an
input-report is smaller than advertised. We could, like i2c, compute the
biggest report-size instead of using HID_MAX_BUFFER_SIZE, but this will
blow up if report-descriptors are changed after ->start() has been called.
So lets be safe and just use the biggest buffer we have.
Note that this adds an additional copy to the HIDP input path. If there is
a way to make sure the skb-buf is big enough, we should use that instead.
The best way would be to make hid-core honor the @size argument, though,
that sounds easier than it is. So lets just fix the buffer-overflows for
now and afterwards look for a faster way for all transport drivers.

HID: hid-sensor-hub: Processing for duplicate physical ids
In HID sensor hub, HID physical ids are used to represent different sensors.
For example physical id of 0x73 in usage page = 0x20, represents an
accelerometer. The HID sensor hub driver uses this physical ids to create
platform devices using MFD. There is 1:1 correspondence between an phy id and a
client driver.
But in some cases these physical ids are reused. There is a phy id 0xe1, which
specifies a custom sensor, which can exist multiple times to represent various
custom sensors. In this case there can be multiple instances of client MFD
drivers, processing specific custom sensor. In this case when client driver
looks for report id or a field index, it should still get the report id
specific to its own type. This is also true for reports, they should be
directed towards correct instance. This change introduce a way to parse and
tie physical devices to their correct instance.
Summary of changes:
- To get physical ids, use collections. If a collection of type=physical
exist then use usage id as in the name of platform device name
- As part of the platform data, we assign a hdsev instance, which has
start and end of collection indexes. Using these indexes attributes
can be tied to correct MFD client instances
- When a report is received, call callback with correct hsdev instance.
In this way using its private data stored as part of its registry, it
can distinguish different sensors even when they have same physical and
logical ids.

HID: fix buffer allocations
When using hid_output_report(), the buffer should be allocated by hid_alloc_report_buf(),
not a custom malloc.

HID: i2c-hid: add runtime PM support
This patch adds runtime PM support for the HID over I2C driver. When the
i2c-hid device is first opened we power it on and on the last close we
power it off. This is actually what the driver is already doing but in
addition it allows subsystems, like ACPI power domain to power off the
device during runtime PM suspend, which should save even more power.
The implementation is not the most power efficient because it needs some
interaction from the userspace (e.g close the device node whenever we are
no more interested in getting events), nevertheless it allows us to save
some power and works with devices that are not wake capable.

HID: microsoft: Add ID's for Surface Type/Touch Cover 2
The Microsoft Surface Type/Touch cover 2 devices have the flag HID_DG_CONTACTID
in their reports.This causes the device to bind to the hid-multitouch driver,
which doesn't handle generic keyboard/mouse input events. The patch adds
the hardware id's of the device to hid-microsoft and to the HID special
driver array, which makes the device get handled by hid-generic/hid-input
properly.
