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

2015-05-06T20:01:52+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

Input: synaptics - handle spurious release of trackstick buttons

2015-04-13T12:03:52+00:00

commit ebc80840b850db72f7ae84fbcf77630ae5409629 upstream.

The Fimware 8.1 has a bug in which the extra buttons are only sent when the
ExtBit is 1.  This should be fixed in a future FW update which should have
a bump of the minor version.

Input: synaptics - fix middle button on Lenovo 2015 products

2015-04-13T12:03:51+00:00

commit dc5465dc8a6d5cae8a0e1d8826bdcb2e4cb261ab upstream.

On the X1 Carbon 3rd gen (with a 2015 broadwell cpu), the physical middle
button of the trackstick (attached to the touchpad serio device, of course)
seems to get lost.

Actually, the touchpads reports 3 extra buttons, which falls in the switch
below to the '2' case. Let's handle the case of odd numbers also, so that
the middle button finds its way back.

Input: synaptics - skip quirks when post-2013 dimensions

2015-04-13T12:03:51+00:00

commit 02e07492cdfae9c86e3bd21c0beec88dbcc1e9e8 upstream.

Post-2013 Lenovo laptops provide correct min/max dimensions, which are
different with the ones currently quirked.  According to
https://bugzilla.kernel.org/show_bug.cgi?id=91541 the following board ids
are assigned in the post-2013 touchpads:

t440p/t440s: LEN0036 -> 2964/2962
t540p:       LEN0034 -> 2964

Using 2961 as the common minimum makes these 3 laptops OK. We may need
to update those values later if other pnp_ids has a lower board_id.

Input: synaptics - support min/max board id in min_max_pnpid_table

2015-04-13T12:03:51+00:00

commit 5b3089ddb540401c1ad2e385a03d7e89ff954585 upstream.

Add a min/max range for board ids to the min/max coordinates quirk. This
makes it possible to restrict quirks to specific models based upon their
board id. The define ANY_BOARD_ID (0) serves as a wild card.

Input: synaptics - remove obsolete min/max quirk for X240

commit b05f4d1c332a22f98c037fa64f249aa30877adaf upstream.

The firmware of the X240 (LEN0035, 2013/12) exposes the same values
    x [1232..5710], y [1156..4696]
as the quirk applies.

Input: synaptics - query min dimensions for fw v8.1

2015-04-13T12:03:50+00:00

commit ac097930f0730a9b777737de2b51e0fc49d2be7a upstream.

Query the min dimensions even if the check
SYN_EXT_CAP_REQUESTS(priv->capabilities) >= 7 fails, but we know that the
firmware version 8.1 is safe.

With that we don't need quirks for post-2013 models anymore as they expose
correct min and max dimensions.

commit 9aff65982d0f58a78a27769fba7e97bc937b2593 upstream.

Logging the dimension values we queried and the values we use from a quirk
to overwrite can be helpful for debugging.

commit 8b04baba10b007f8b6c245a50be73cf09cc3a414 upstream.

Split the function synaptics_resolution() into synaptics_resolution() and
synaptics_quirks().  synaptics_resolution() will be called before
synaptics_quirks() to query dimensions and resolutions before overwriting
them with quirks.
