Unlike previous Xbox pads, the Xbox One pad doesn't have "sticky" rumble
packets. The duration is encoded into the command and expiration is handled

ff-memless needs pseudo-sticky behavior for rumble effects to behave
properly for long duration effects. We already specify the maximum rumble
on duration in the command packets, but it's still only good for about 2.5
seconds of rumble. This is easily reproducible running fftest's sine
vibration test.
It turns out there's a repeat count encoded in the rumble command. We can
abuse that to get the pseudo-sticky behavior needed for rumble to behave as
expected for effects with long duration.
By my math, this change should allow a single ff_effect to rumble for 10
minutes straight, which should be more than enough for most needs.

it has 14 bits resolution instead of 10, and it has quite different

Treating the bma180 as a bma150 wrt its data registers will just result

Since some setups depend on the evdev interface the bma150 driver offers

Input: synaptics-rmi4 - add parameters for dribble packets and palm detect gesture
The rmi_f11 driver currently disables dribble packets and the palm detect
gesture for all devices. This patch creates a parameter in the 2d sensor
platform data for controlling this functionality on a per device basis.
For more information on dribble packets:

touchpads")

Input: synaptics-rmi4 - handle incomplete input data
Commit
5b65c2a02966 ("HID: rmi: check sanity of the incoming report") added
support for handling incomplete HID reports do to the input data being
corrupted in transit. This patch reimplements this functionality in the
function drivers so they can handle getting less valid data then they
expect.

Input: synaptics-rmi4 - move IRQ handling to rmi_driver
The attn IRQ is related to the chip, rather than the transport, so move
all handling of interrupts to the core driver. This also makes sure that
there are no races between interrupts and availability of the resources
used by the core driver.

Input: da9062 - update bindings docs to account for da9061
Add binding information for DA9061 onkey.
This patch updates the compatible string "dlg,da9061-onkey" to support
DA9061, removes the reference to KEY_SLEEP (which the driver no longer
supports) and fixes a typo in the example for DA9063.
Supporting KEY_SLEEP was not the general convention and the typical
solution should have been for KEY_POWER to support both cases of suspend
and S/W power off. This change was sent to the DA9063 ONKEY device
driver in a separate patch, but the documentation was not updated at
that time.

f889bea Report KEY_POWER instead of KEY_SLEEP during power key-press
This patch also adds two new examples, one for DA9062 and one for DA9061.
The DA9061 examples uses a fall-back compatible string for the DA9062
onkey driver.
