This patch adds keyboard support for MacbookPro12,1 as WELLSPRING9
(0x0272, 0x0273, 0x0274). The touchpad is handled in a separate
bcm5974 patch, as usual.

Current implementation of cp2112_raw_event() only accepts one data report at a
time. If last received data report is not fully handled yet, a new incoming
data report will overwrite it. In such case we don't guaranteed to propagate
the correct incoming data.
The trivial fix implemented here forces a single report at a time by requesting
in cp2112_read() no more than 61 byte of data, which is the payload size of a
single data report.

Commit 862cf55 ("HID: wacom: Introduce a new WACOM_DEVICETYPE_PAD device_type")
neglected to set the WACOM_DEVICETYPE_PAD flag for older two-finger Bamboo
Touch tablets. Not only does this result in the pad device not appearing when
such a tablet is plugged in, but also causes a segfault when 'wacom_bpt_touch'
tries to send pad events. This patch adds the flag to resolve these issues.

Fields like HID_DG_CONTACTCOUNT are outside of the physical collection,
but within the application collection and report ID. Make sure to catch
those fields that are not part of the mt_report_id and return 0 so they
can be processed with the pen. Otherwise, the wrong HID_DG_CONTACTCOUNT
will be applied to cc_index and result in dereferencing a null pointer in
mt_touch_report.

Instead of having a single 'input_dev' device that will take either pen
or touch data depending on the type of the device, create seperate devices
devices for each. By splitting things like this, we can support devices
(e.g. the I2C "AES" sensors in some newer tablet PCs) that send both pen
and touch reports from a single endpoint.

This splits the 'wacom_setup_pentouch_input_capabilites' function into
pieces dedicated to doing setup for just the pen interface and just
the touch interface. This makes it easier to focus on the relevant
piece when making changes.
This patch introduces no functional changes.

Historically, both the touch and pad tools would have shared the
'BTN_TOOL_FINGER' type. Any time you needed to distinguish the two, you
had to use some other bit of knowledge (e.g. that the pad was on the same
interface as the pen, and thus 'touch_max' would be zero).
To make these checks more readable, we introduce WACOM_DEVICETYPE_PAD.
Although we still have to rely on other bits of knowledge to set this
bit on the right interface (since it cannot be detected from the HID
descriptor), it can be done just once inside 'wacom_setup_device_quirks'.
This patch introduces no functional changes.

The USB devices that this driver has historically supported segregate the
pen and touch portions of the tablet. Oftentimes the segregation would be
done at the interface level, though on occasion (e.g. Cintiq 24HDT) the
tablet would combine two totally independent USB devices behind an internal
USB hub. Because pen and touch never shared the same interface, it made
sense for the 'device_type' to store a single value: "pen" or "touch".
Recently, however, some I2C devices have been created which combine the
two. A first step to accomodating this is to expand 'device_type' so that
it can represent two (or potentially more) types simultaneously. To do
this, we treat it as a bitfield and set/check individual bits rather
than using the '=' and '==' operators.
This should not result in any functional change since no supported devices
(that I'm aware of, at least) have HID descriptors that indicate both
pen and touch reports on a single interface.

Hardware may not respond to a request for the HID_DG_CONTACTMAX feature and
we should be tolerant of such a failure. This is especially true when using
hid-replay where the hardware doesn't exist, but also for devices attached
to a flaky bus. This patch increases the number of allowable retries to
match other calls to 'wacom_get_report' and also provides a fallback which
forces 'touch_max = 16' (enough for any Wacom device seen so far).

Retrying on -EPIPE makes very little sense since this typically indicates
a problem that will not just disappear on its own. For instance, the USB
documentation states that it will be sent if the endpoint is stalled or
the device has disconnected. Instead, we should retry if -EAGAIN is
received since this indicates a temporary error condition such as a busy
bus.
In addition to adjusting the conditions we retry under, we also log an
error on failure so that we can be aware of what's going on.

The last patch was careful to maintain backwards-compatible behavior
by forcing device_type to BTN_TOOL_PEN (and printing a warning) if it
were still uninitialized after scanning the HID descriptor and applying
quirks. We should be more strict with HID_GENERIC devices, however,
since there is no a priori guarantee that it is a tablet or touchpad.
If the device_type is still uninitialized for a HID_GENERIC device then
we assume that it isn't something the driver can work with and so fail
the probe.

Currently, we assume a device_type of BTN_TOOL_PEN before scanning the
HID descriptor and then change the device_type if what we discover
proves that assumption wrong. This way of doing things makes it more
difficult to figure out if a device (particularly a HID_GENERIC device)
actually does tablet/touch input or is something completley different.
This patch leaves device_type at its initial value of 0 and then calls
'wacom_parse_hid' for every device (not just those that have touch).
As we map the usages, we can set the device_type as before. After we're
finished, we can then check if the value is still zero and do whatever
is most appropriate.
Detecting the pen can be a little tricky on most Wacom devices because
the descriptors describe opaque blobs. Fortunately, older Wacom tablets
have the HID_DG_DIGITIZER usage on the pen's application collection and
newer tablets seem to have a similar vendor-defined usage that we can
trigger on.

The naming logic currently assumes that all devices will be a pen, finger,
or pad. Though this has historically been the case, the new HID_GENERIC
catch-all may cause us to probe devices with Wacom's 056A VID which aren't
any of these types (e.g. the "Cintiq 24HDT Monitor Control"). This patch
updates the logic so that no suffix will be added to the device name if
the device type is unknown.

HID generic devices share the same default name, "Wacom HID". This
causes userland programs to show same device names for different
devices, which would confuse end users with same device names for
different devices too.
This patch uses name retrieved from HID descriptor, if a meaningful
name is reported. Otherwise, affix its product ID to "Wacom HID".
Names from descriptor may contain extra whitespaces. To comfort
readers' eyes, we removed those extra whitespaces too.

The Accelerometers and Gyros (1st frame only) are also reported as axis, but
the Magnetometers are NOT as 'fixing' their byte order would break user-space
drivers such as PSMoveAPI.
It is hoped to resolve this at a future time.

updating LED states
Directly set the initial LED states in the device state struct instead
of copying them from a temporary array.
This allows for the removal of a redundant "x = x" copy loop in
sony_set_leds() that was taking place any time an LED was updated.
It also allows for the simplifying of the parameters in functions dealing
with LED initialization and updates since only a pointer to the sony_sc
struct is needed now.

Add a fixed-up HID descriptor for the Sony motion controller and enable
controls for the LED light as well as force-feedback.
The LED is multi-colored (red, green, blue).
The motion controller has a single rumble motor so the higher of the left

sony_allocate_output_report() was being called before sony_set_device_id()
which meant that an unallocated ida value was was freed if the output
report allocation failed and the probe function jumped to err_stop.
Do the device ID allocation before the output report allocation to avoid
freeing an unallocated value in case of a failure.

Physical buttons do not use F30 to report their state and in some cases the
data reported in F30 is incorrect and inconsistent with what is reported by
the HID descriptor. When physical buttons are present, ignore F30 and let
hid-input report buttons based on what is defined in the HID descriptor.

The HID device does not need to know about the ACPI device associated with
the underlying i2c device. Setting the ACPI companion field in the HID device
also has the side effect of causing HID to be set as wake capable, since
acpi_bind_one uses's the companion ACPI device's wakeup flags to set the
device as wake capable. Which results in power/wakeup files in sysfs for
the HID device which do not do anything.

The Logitech M560 is a wireless mouse designed for windows 8 which uses
the unifying receiver.
Compared to a standard one, some buttons (the middle one and the
two ones placed on the side) are bound to a key combination
instead of a generating classic "mouse" button events.
The device shows up as a mouse and keyboard combination: when the middle
button is pressed it sends a key (as keyboard) combination, the same
happens for the two side button. The left/right/wheel work as expected
from a mouse. To complicate things further, the middle button sends
different keys combinations between odd and even presses.
In the "even" press it also sends a left click. But the worst thing
is that no event is generated when the middle button is released.
It is possible to re-configure the mouse sending a command (see function
m560_send_config_command()). After this command the mouse sends some
useful data when the buttons are pressed and/or released.
