For the touch chip use on the new OLED panel(rm67199), when touch
the screen, GT1151Q sends a falling edge pulse via INT pin.For code logic, it will read the touch internal config data, the bit[1~0]
of config[6] means the interrupt trigger method. For this GT1151Q, this
bit[1~0] is 3 in default, which means IRQ_TYPE_LEVEL_HIGH, which not
match with the datasheet and the hardware behavior. Since the default
level of the INT pin is high, so after driver probe, a lot of useless
touch interrupts keep triggered.
To fix this, need to update the touch firmware. Set the bit[1~0] of config[6]
to value 1. Since we lack the touch firmware file, as a workaround, add a
property "edge-failling-trigger" in dts file, if has this property, force
set the IRQ_TYPE_EDGE_FALLING.Signed-off-by: Haibo Chen

MMS345L is another first generation touch screen from Melfas,
which uses mostly the same registers as MMS152.However, there is some garbage printed during initialization.
Apparently MMS345L does not have the MMS152_COMPAT_GROUP register
that is read+printed during initialization.TSP FW Rev: bootloader 0x6 / core 0x26 / config 0x26, Compat group: \x06
On earlier kernel versions the compat group was actually printed as
an ASCII control character, seems like it gets escaped now.But we probably shouldn't print something from a random register.
Add a separate "melfas,mms345l" compatible that avoids reading
from the MMS152_COMPAT_GROUP register. This might also help in case
there is some other device-specific quirk in the future.Signed-off-by: Stephan Gerhold

On the Lenovo ThinkPad Twist S230u (3347-4HU) with BIOS version
"GDETC1WW (1.81 ) 06/27/2019", the keyboard, Synaptics TouchPad, and
TrackPoint either do not function or stop functioning a few minutes
after boot. This problem has been noted before, perhaps only occurring
with BIOS 1.57 and later.[1][2][3][4][5]Odds of a BIOS fix appear to be low: 1.57 was released over 6 years ago
and although the [BIOS changelog] notes "Fixed an issue of UEFI
touchpad/trackpoint/keyboard/touchscreen" in 1.58, it appears to be
insufficient.Setting i8042.reset=1 or adding 33474HU to the reset list avoids the
issue on my system from either warm or cold boot.[1]: https://bugs.launchpad.net/bugs/1210748

input_flush_device() should only be called once the struct file is being
released and no open descriptors remain, but evdev_flush() was calling
it whenever a file descriptor was closed.This caused uploaded force-feedback effects to be erased when a process
did a dup()/close() on the event FD, called system(), etc.Call input_flush_device() from evdev_release() instead.

commit ebc68cedec4aead47d8d11623d013cca9bf8e825 upstream.
The Acer Aspire 5738z has a button to disable (and re-enable) the
touchpad next to the touchpad.When this button is pressed a LED underneath indicates that the touchpad
is disabled (and an event is send to userspace and GNOME shows its
touchpad enabled / disable OSD thingie).So far so good, but after re-enabling the touchpad it no longer works.
The laptop does not have an external ps2 port, so mux mode is not needed
and disabling mux mode fixes the touchpad no longer working after toggling
it off and back on again, so lets add this laptop model to the nomux list.Signed-off-by: Hans de Goede

commit 5179a9dfa9440c1781816e2c9a183d1d2512dc61 upstream.
The Yoga 11e is using LEN0049, but it doesn't have a trackstick.
Thus, there is no need to create a software top buttons row.
However, it seems that the device works under SMBus, so keep it as part

We observed a large(order-3) allocation in evdev_open() and it may
cause an OOM kernel panic in kzalloc(), before we getting to the
vzalloc() fallback.Fix it by converting kzalloc()/vzalloc() to kvzalloc() to avoid the
OOM killer logic as we have a vmalloc fallback.InputReader invoked oom-killer: gfp_mask=0x240c2c0
