2a6cdbdd4c HID: wacom: Introduce new 'touch_input' device
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.

2636a3f2d1 HID: wacom: Split apart 'wacom_setup_pentouch_input_capabilites'
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.

862cf5535c HID: wacom: Introduce a new WACOM_DEVICETYPE_PAD device_type
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.

aa86b18cc9 HID: wacom: Treat features->device_type values as flags
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.

8b2513c313 HID: sony: PS Move fix report descriptor
Fix the report descriptor so that the buttons and trigger are correctly reported.

The format of the input report is described here:
https://github.com/nitsch/moveonpc/wiki/Input-report

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.

3e48138c2c HID: i2c-hid: Do not set the ACPI companion field in the HID device
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.

8a09b4fadf HID: hidpp: Add driver for mouse logitech M560
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.

05e8fd9202 HID: wacom: Handle failing HID_DG_CONTACTMAX requests
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).

aef3156d72 HID: wacom: Have wacom_{get,set}_report retry on -EAGAIN, not -EPIPE
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.

1e70897d0e pwm: img: Impose upper and lower timebase steps value
The PWM hardware on Pistachio platform has a maximum timebase steps
value to 255. To fix it, let's introduce a compatible-specific
data structure to contain the SoC-specific details and use it to
specify a maximum timebase.

Also, let's limit the minimum timebase to 16 steps, to allow a sane
range of duty cycle steps.

ab992dc38f watchdog: Fix merge 'conflict'
Two watchdog changes that came through different trees had a non
conflicting conflict, that is, one changed the semantics of a variable
but no actual code conflict happened. So the merge appeared fine, but
the resulting code did not behave as expected.

Commit 195daf665a ("watchdog: enable the new user interface of the
watchdog mechanism") changes the semantics of watchdog_user_enabled,
which thereafter is only used by the functions introduced by
b3738d2932 ("watchdog: Add watchdog enable/disable all functions").

There further appears to be a distinct lack of serialization between
setting and using watchdog_enabled, so perhaps we should wrap the
{en,dis}able_all() things in watchdog_proc_mutex.

This patch fixes a s2r failure reported by Michal; which I cannot
readily explain. But this does make the code internally consistent
again.
