Input: i8042 - add Clevo P650RS to the i8042 reset list

2017-05-09T06:19:55+00:00

commit 7c5bb4ac2b76d2a09256aec8a7d584bf3e2b0466 upstream.

Clevo P650RS and other similar devices require i8042 to be reset in order
to detect Synaptics touchpad.

Input: elantech - add Fujitsu Lifebook E547 to force crc_enabled

2017-05-09T06:19:36+00:00

commit 704de489e0e3640a2ee2d0daf173e9f7375582ba upstream.

Temporary got a Lifebook E547 into my hands and noticed the touchpad
only works after running:

	echo "1" > /sys/devices/platform/i8042/serio2/crc_enabled

Add it to the list of machines that need this workaround.

Input: mpr121 - set missing event capability

2017-04-11T06:04:40+00:00

commit 9723ddc8fe0d76ce41fe0dc16afb241ec7d0a29d upstream.

This driver reports misc scan input events on the sensor's status
register changes.  But the event capability for them was not set in the
device initialization, so these events were ignored.

This change adds the missing event capability.

Input: mpr121 - handle multiple bits change of status register

2017-04-11T06:04:39+00:00

commit 08fea55e37f58371bffc5336a59e55d1f155955a upstream.

This driver reports input events on their interrupts which are triggered
by the sensor's status register changes.  But only single bit change is
reported in the interrupt handler.  So if there are multiple bits are
changed at almost the same time, other press or release events are ignored.

This fixes it by detecting all changed bits in the status register.

Input: tca8418 - use the interrupt trigger from the device tree

2017-04-11T06:04:39+00:00

commit 259b77ef853cc375a5c9198cf81f9b79fc19413c upstream.

The TCA8418 might be used using different interrupt triggers on various
boards. This is not working so far because the current code forces a
falling edge trigger.

The device tree already provides a trigger type, so let's use whatever it
sets up, and since we can be loaded without DT, keep the old behaviour for
the non-DT case.

Input: joydev - do not report stale values on first open

2017-04-11T06:04:38+00:00

commit 45536d373a21d441bd488f618b6e3e9bfae839f3 upstream.

Postpone axis initialization to the first open instead of doing it
in joydev_connect. This is to make sure the generated startup events
are representative of the current joystick state rather than what
it was when joydev_connect() was called, potentially much earlier.
Once the first user is connected to joydev node we'll be updating
joydev->abs[] values and subsequent clients will be getting correct
initial states as well.

This solves issues with joystick driven menus that start scrolling
up each time they are started, until the user moves the joystick to
generate events. In emulator menu setups where the menu program is
restarted every time the game exits, the repeated need to move the
joystick to stop the unintended scrolling gets old rather quickly...
