Previously, both usbhid and usbtouchscreen would bind to D-WAV devices
with class HID and protocol None, so they would be claimed by whichever
driver was loaded first.  Some of these devices do in fact work with
usbhid, but not all of them do.  OTOH they all work with usbtouchscreen
as of commit 037a833e ("Input:
usbtouchscreen - initialize eGalax devices").  So we ignore them in
usbhid to prevent getting in the way of usbtouchscreen and claiming an
interface that we may not be able to do anything useful with.

Add a driver for the ION iCade mini arcade cabinet [1]. The device generates a
key press and release for each joystick movement or button press or release.
For example, moving the stick to the left will generate the "A" key being
pressed and then released.

A list of all the combinations is available in the iCade developer guide [2].

This driver hides all this and makes the device work as a generic joystick.

The Sony PS3 Blue-ray Disc Remote Control used to be supported by the
BlueZ project's user space, but the code that handled it was recently
removed as its functionality conflicted with a real HSP implementation
and the mapping was thought to be better handled in the kernel. This is
a port of the mapping logic from the fakehid driver by Marcel Holtmann
to the in-kernel HID layer.

We also add support for the Logitech Harmony Adapter for PS3, which
emulates the BD Remote.

The dev_rdesc member of the hid_device structure is meant to store the original
report descriptor received from the device, but it is currently passed to any
report_fixup method before it is copied to the rdesc member. This patch uses a
temporary buffer to shield dev_rdesc from the side effects of many HID drivers'
report_fixup implementations.

usbhid's hid_post_reset checks the report descriptor currently returned by the
device against a descriptor that may have been modified by a driver's
report_fixup method. That leaves some devices nonfunctional after a resume, with
a "reset_resume error 1" reported. This patch checks the new descriptor against
the unmodified dev_rdesc instead and uses the original, instead of modified,
report size.

The Freescale i.MX28 BootROM USB recovery mode implements the USB HID
protocol, yet the global item tag report size is 128. Linux checks if
this is 96 as of now, see [1]. This causes Linux to refuse to communicate
with this device, making it impossible to use the recovery mode.

This is not a standard HID device per se, but rather a software emulation
implemented within the BootROM code and realized through USB OTG-capable
port switched to device mode present on the device.

Previous attempt to discuss this issue dates back to 2011, see [2]. There
has been not much response. Also noteworthy is the [3], where there seems
to be a pointing device that has issue similar to this one.

The tool making use of the USB recovery mode is available at [4].

hid-picolcd and hid-wiimote do not allow any of hidinput, hiddev or hidraw
to claim the device but still want to remain on the bus. Hence, if a
driver uses the raw_event callback but no other listener claimed the
device, we still leave it on the bus as the driver handles everything by
itself. It thus becomes its own listener.

Under some circumstances (eg., hidinput_connect() fails and raw_event set)
a device may be left on the bus even though it requires external
listeners. But then if hidinput_connect() fails there are bigger issues
than a device that is left unhandled. So we can safely use this heuristic
to avoid adding another flag for special devices like hid-picolcd and
hid-wiimote.

This also removes the ugly hack from hid-picolcd as this is no longer
required.

Switch the driver over to device group handling.  By adding the
HID_GROUP_MULTITOUCH group to hid-core, hid-generic will no longer
match multitouch devices.  By adding the HID_GROUP_MULTITOUCH entry to
the device list, hid-multitouch will match all unknown multitouch
devices, and udev will automatically load the module.

Since HID_QUIRK_MULTITOUCH never gets set, the special quirks handling
can be removed.  Since all HID MT devices have HID_DG_CONTACTID, they
can be removed from the hid_have_special_driver list.

With this patch, the unknown device ids are no longer NULL, so the code

In order to allow the report descriptor to influence the hid device
properties, one needs to parse the descriptor early, without reference
to any driver. Scan the descriptor for group information during device
add, before the device has been broadcast to userland. The device

differentiate between modules. For starters, just handle the generic

HID devices are only partially presented to userland.  Hotplugged
devices emit events containing a modalias based on the basic bus,
vendor and product entities. However, in practise a hid device can
depend on details such as a single usb interface or a particular item
in a report descriptor.

This patch adds a device group to the hid device id, and broadcasts it
using uevent and the device modalias.  The module alias generation is
modified to match. As a consequence, a device with a non-zero group
will be processed by the corresponding group driver instead of by the
generic hid driver.

The low-level driver can read the report descriptor, but it cannot
determine driver-specific changes to it. The hid core can fixup
and parse the report descriptor during driver attach, but does
not have direct access to the descriptor when doing so.

To be able to handle attach/detach of hid drivers properly,
a semantic change to hid_parse_report() is needed. This function has
been used in two ways, both as descriptor reader in the ll drivers and
as a parsor in the probe of the drivers. This patch splits the usage
by introducing hid_open_report(), and modifies the hid_parse() macro
to call hid_open_report() instead. The only usage of hid_parse_report()
is then to read and store the device descriptor. As a consequence, we
can handle the report fixups automatically inside the hid core.
