Input: cypress_ps2 - do not consider data bad if palm is detected

2013-12-04T18:57:18+00:00

commit 5df682b297f6b23ec35615ed7bb50cbb25d25869 upstream.

If hardware (or firmware) detects palm on the surface of the device it does
not mean that the data packet is bad from the protocol standpoint. Instead
of reporting PSMOUSE_BAD_DATA in this case simply threat it as if nothing
touches the surface.

HID: Correct the USB IDs for the new Macbook Air 6

2013-09-27T00:18:15+00:00

commit 8c89cc17b91992845bd635813cd162fe8dfcec6e upstream.

A recent patch (9d9a04ee) added support for the new machine, but got
the sequence of USB ids wrong. Reports from both Ian and Linus T show
that the 0x0291 id is for ISO, not ANSI, which should have the missing
number 0x0290. This patchs moves the three numbers accordingly, fixing
the problem.

Input: bcm5974 - add support for the 2013 MacBook Air

2013-07-22T01:21:29+00:00

commit 148c1c8ad3c4170186ebe6ea5900adde27d2a0e7 upstream.

The June 2013 Macbook Air (13'') has a new trackpad protocol; four new
values are inserted in the header, and the mode switch is no longer
needed. This patch adds support for the new devices.

Input: synaptics - fix sync lost after resume on some laptops

2013-06-04T16:33:16+00:00

In summary, the symptom is intermittent key events lost after resume
on some machines with synaptics touchpad (seems this is synaptics _only_),
and key events loss is due to serio port reconnect after psmouse sync lost.
Removing psmouse and inserting it back during the suspend/resume process
is able to work around the issue, so the difference between psmouse_connect()
and psmouse_reconnect() is the key to the root cause of this problem.

After comparing the two different paths, synaptics driver has its own
implementation of synaptics_reconnect(), and the missing psmouse_probe()
seems significant, the patch below added psmouse_probe() to the reconnect
process, and has been verified many times that the issue could not be reliably
reproduced.

There are two PS/2 commands in psmouse_probe():

  1. PSMOUSE_CMD_GETID
  2. PSMOUSE_CMD_RESET_DIS

Only the PSMOUSE_CMD_GETID seems to be significant. The
PSMOUSE_CMD_RESET_DIS is irrelevant to this issue after trying
several times.  So we have only implemented this patch to issue
the PSMOUSE_CMD_GETID so far.

Input: trackpoint - Optimize trackpoint init to use power-on reset

2013-04-19T16:05:44+00:00

The trackpoint driver sets various parameter default values, all of
which happen to be power-on defaults (Source: IBM TrackPoint Engineering
Specification, Version 4.0. Also confirmed by empirical data).

By sending the power-on reset command to reset all parameters to
power-on state, we can skip the lengthy process of programming all
parameters. In testing, ~2.5 secs of time writing parameters was reduced
to .35 seconds waiting for power-on reset to complete.

GENERIC_GPIO is now equivalent to GPIOLIB and features that depended on
GENERIC_GPIO can now depend on GPIOLIB to allow removal of this option.
