Input: usbtouchscreen - avoid unresponsive TSC-30 touch screen

2015-08-19T06:36:39+00:00

commit 968491709e5b1aaf429428814fff3d932fa90b60 upstream.

This patch fixes a problem in the usbtouchscreen driver for DMC TSC-30
touch screen.  Due to a missing delay between the RESET and SET_RATE
commands, the touch screen may become unresponsive during system startup or
driver loading.

According to the DMC documentation, a delay is needed after the RESET
command to allow the chip to complete its internal initialization. As this
delay is not guaranteed, we had a system where the touch screen
occasionally did not send any touch data. There was no other indication of
the problem.

The patch fixes the problem by adding a 150ms delay between the RESET and
SET_RATE commands.

Input: elantech - fix detection of touchpads where the revision matches a known rate

2015-06-23T12:55:11+00:00

commit 5f0ee9d17aae628b22be86966471db65be21f262 upstream.

Make the check to skip the rate check more lax, so that it applies
to all hw_version 4 models.

This fixes the touchpad not being detected properly on Asus PU551LA
laptops.

Input: elantech - fix semi-mt protocol for v3 HW

2015-06-03T09:33:14+00:00

commit 3c0213d17a09601e0c6c0ae0e27caf70d988290f upstream.

When the v3 hardware sees more than one finger, it uses the semi-mt
protocol to report the touches. However, it currently works when
num_fingers is 0, 1 or 2, but when it is 3 and above, it sends only 1
finger as if num_fingers was 1.

This confuses userspace which knows how to deal with extra fingers
when all the slots are used, but not when some are missing.

Input: xpad - add support for Xbox One controllers

2015-05-26T14:26:57+00:00

commit 1a48ff81b3912be5fadae3fafde6c2f632246a4c upstream.

Xbox One controllers require an initialization message to start sending
data, so xpad_init_output becomes a required function. The Xbox One
controller does not have LEDs like the Xbox 360 controller, so that
functionality is not implemented. The format of messages controlling rumble
is currently undocumented, so rumble support is not yet implemented.

Note that Xbox One controller advertises three interfaces with the same
interface class, subclass and protocol, so we have to also match against
interface number.

Input: cros_ec_keyb - fix clearing keyboard state on wakeup

2015-05-26T14:26:57+00:00

commit ef30a406468a3eae007210ae0dc5ed8d5eb59b7d upstream.

As the comment right before explains, the keyboard state is to be cleared
only if the EC wasn't a wakeup source in the last suspend.

Without this commit, there's an unneeded delay when resuming from suspend
and we also lose the key that was pressed while suspended.

Input: elantech - fix absolute mode setting on some ASUS laptops

2015-05-04T09:50:01+00:00

commit bd884149aca61de269fd9bad83fe2a4232ffab21 upstream.

On ASUS TP500LN and X750JN, the touchpad absolute mode is reset each
time set_rate is done.

In order to fix this, we will verify the firmware version, and if it
matches the one in those laptops, the set_rate function is overloaded
with a function elantech_set_rate_restore_reg_07 that performs the
set_rate with the original function, followed by a restore of reg_07
(the register that sets the absolute mode on elantech v4 hardware).

Also the ASUS TP500LN and X750JN firmware version, capabilities, and
button constellation is added to elantech.c
