Input: xpad - use proper endpoint type

2014-12-06T14:18:21+00:00

commit a1f9a4072655843fc03186acbad65990cc05dd2d upstream.

The xpad wireless endpoint is not a bulk endpoint on my devices, but
rather an interrupt one, so the USB core complains when it is submitted.
I'm guessing that the author really did mean that this should be an
interrupt urb, but as there are a zillion different xpad devices out
there, let's cover out bases and handle both bulk and interrupt
endpoints just as easily.

Input: synaptics - adjust min/max on Thinkpad E540

2014-12-06T14:18:21+00:00

commit bce4f9e764c36bc35dd5c9cf9e057c09f422397d upstream.

The LEN2006 Synaptics touchpad (as found in Thinkpad E540) returns wrong
min max values.

touchpad-edge-detector output:
>  Touchpad SynPS/2 Synaptics TouchPad on /dev/input/event6
>  Move one finger around the touchpad to detect the actual edges
>  Kernel says:    x [1472..5674], y [1408..4684]
>  Touchpad sends: x [1264..5675], y [1171..4688]

Input: synaptics - add min/max quirk for Lenovo T440s

2014-12-06T14:02:57+00:00

commit e4742b1e786ca386e88e6cfb2801e14e15e365cd upstream.

The new Lenovo T440s laptop has a different PnP ID "LEN0039", and it
needs the similar min/max quirk to make its clickpad working.

Input: synaptics - fix resolution for manually provided min/max

2014-12-06T14:02:57+00:00

commit d49cb7aeebb974713f9f7ab2991352d3050b095b upstream.

commit 421e08c41fda fixed the reported min/max for the X and Y axis,
but unfortunately, it broke the resolution of those same axis.

On the t540p, the resolution is the same regarding X and Y. It is not
a problem for xf86-input-synaptics because this driver is only interested
in the ratio between X and Y.
Unfortunately, xf86-input-cmt uses directly the resolution, and having a
null resolution leads to some divide by 0 errors, which are translated by
-infinity in the resulting coordinates.

Input: synaptics - change min/max quirk table to pnp-id matching

2014-12-06T14:02:56+00:00

commit 0f68f39c393bc06ac5ccc8794f0e2ed841e41c3e upstream.

Most of the affected models share pnp-ids for the touchpad. So switching
to pnp-ids give us 2 advantages:
1) It shrinks the quirk list
2) It will lower the new quirk addition frequency, ie the recently added W540
   quirk would not have been necessary since it uses the same LEN0034 pnp ids
   as other models already added before it

As an added bonus it actually puts the quirk on the actual psmouse, rather
then on the machine, which is technically more correct.

Input: serio - add firmware_id sysfs attribute

2014-12-06T13:48:31+00:00

commit 0456c66f4e905e1ca839318219c770988b47975c upstream.

serio devices exposed via platform firmware interfaces such as ACPI may
provide additional identifying information of use to userspace.

We don't associate the serio devices with the firmware device (we don't
set it as parent), so there's no way for userspace to make use of this
information.

We cannot change the parent for serio devices instantiated though a
firmware interface as that would break suspend / resume ordering.

Therefore this patch adds a new firmware_id sysfs attribute so that
userspace can get a string from there with any additional identifying
information the firmware interface may provide.
