Input: i8042 - add Pegatron touchpad to noloop table

2017-01-26T16:40:32+00:00

commit 41c567a5d7d1a986763e58c3394782813c3bcb03 upstream.

Avoid AUX loopback in Pegatron C15B touchpad, so input subsystem is able
to recognize a Synaptics touchpad in the AUX port.

(Touchpad is not detected on DNS 0801480 notebook (PEGATRON C15B))

Input: xpad - use correct product id for x360w controllers

2017-01-26T16:40:31+00:00

commit b6fc513da50c5dbc457a8ad6b58b046a6a68fd9d upstream.

currently the controllers get the same product id as the wireless
receiver. However the controllers actually have their own product id.

The patch makes the driver expose the same product id as the windows
driver.

This improves compatibility when running applications with WINE.

Input: i8042 - add XMG C504 to keyboard reset table

2016-11-24T15:23:27+00:00

commit da25311c7ca8b0254a686fc0d597075b9aa3b683 upstream.

The Schenker XMG C504 is a rebranded Gigabyte P35 v2 laptop.
Therefore it also needs a keyboard reset to detect the Elantech touchpad.
Otherwise the touchpad appears to be dead.

With this patch the touchpad is detected:

Input: elantech - add Fujitsu Lifebook E556 to force crc_enabled

2016-10-28T18:37:00+00:00

commit 62837b3c1a95535d1a287c9c8c6563bbd8d37033 upstream.

Another Lifebook machine that needs the same quirk as other similar
models to make the driver working.

Also let's reorder elantech_dmi_force_crc_enabled list so LIfebook enries
are in alphabetical order.

Input: elantech - force needed quirks on Fujitsu H760

2016-10-28T18:36:59+00:00

commit f9a703a54d16ba2470391c4b12236ee56591d50c upstream.

Just like Fujitsu CELSIUS H730, the H760 also has an Elantech touchpad with
the same quirks. Without this patch, the touchpad is useless out-of-the-box
as the mouse pointer won't move.

This patch makes the driver aware of both the crc_enabled=1 requirement and
the middle button, making the touchpad fully functional out-of-the-box.

Input: ili210x - fix permissions on "calibrate" attribute

commit b27c0d0c3bf3073e8ae19875eb1d3755c5e8c072 upstream.

"calibrate" attribute does not provide "show" methods and thus we should
not mark it as readable.

Input: i8042 - set up shared ps2_cmd_mutex for AUX ports

2016-09-23T07:29:21+00:00

commit 47af45d684b5f3ae000ad448db02ce4f13f73273 upstream.

The commit 4097461897df ("Input: i8042 - break load dependency ...")
correctly set up ps2_cmd_mutex pointer for the KBD port but forgot to do
the same for AUX port(s), which results in communication on KBD and AUX
ports to clash with each other.

Input: i8042 - break load dependency between atkbd/psmouse and i8042

2016-09-21T11:40:10+00:00

commit 4097461897df91041382ff6fcd2bfa7ee6b2448c upstream.

As explained in 1407814240-4275-1-git-send-email-decui@microsoft.com we
have a hard load dependency between i8042 and atkbd which prevents
keyboard from working on Gen2 Hyper-V VMs.

> hyperv_keyboard invokes serio_interrupt(), which needs a valid serio
> driver like atkbd.c.  atkbd.c depends on libps2.c because it invokes
> ps2_command().  libps2.c depends on i8042.c because it invokes
> i8042_check_port_owner().  As a result, hyperv_keyboard actually
> depends on i8042.c.
>
> For a Generation 2 Hyper-V VM (meaning no i8042 device emulated), if a
> Linux VM (like Arch Linux) happens to configure CONFIG_SERIO_I8042=m
> rather than =y, atkbd.ko can't load because i8042.ko can't load(due to
> no i8042 device emulated) and finally hyperv_keyboard can't work and
> the user can't input: https://bugs.archlinux.org/task/39820
> (Ubuntu/RHEL/SUSE aren't affected since they use CONFIG_SERIO_I8042=y)

To break the dependency we move away from using i8042_check_port_owner()
and instead allow serio port owner specify a mutex that clients should use
to serialize PS/2 command stream.
