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

2014-05-26T22:02:00+00:00

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.

This is a preparation patch for simplifying the min/max quirk table.

Input: synaptics - T540p - unify with other LEN0034 models

2014-05-26T22:01:25+00:00

The T540p has a touchpad with pnp-id LEN0034, all the models with this
pnp-id have the same min/max values, except the T540p where the values are
slightly off. Fix them to be identical.

This is a preparation patch for simplifying the quirk table.

Input: fix ps2/serio module dependency

2014-05-12T19:33:52+00:00

The ps2 mouse and keyboard drivers use the "serio" framework that they
correctly select in Kconfig, and that in turn depends on the i8042 driver,
which is also allowed to be disabled for architectures that don't have an
i8042.

However, Kconfig also allows i8042 to be built as a module while
the serio framework is built-in, which causes this link error:

drivers/built-in.o: In function `ps2_begin_command':
:(.text+0x26b6cc): undefined reference to `i8042_check_port_owner'
:(.text+0x26b6d4): undefined reference to `i8042_lock_chip'
drivers/built-in.o: In function `ps2_end_command':
:(.text+0x26b734): undefined reference to `i8042_check_port_owner'
:(.text+0x26b73c): undefined reference to `i8042_unlock_chip'

On x86, a specific 'select SERIO_I8042' takes care of it, but
not on the other architecture that potentially have a i8042.

This patch changes the Kconfig logic to ensure that whenever
there is an i8042, it does get used for the serio driver, avoiding
the link error above.

Input: elantech - fix touchpad initialization on Gigabyte U2442

2014-05-05T19:34:22+00:00

The hw_version 3 Elantech touchpad on the Gigabyte U2442 does not accept
0x0b as initialization value for r10, this stand-alone version of the
driver: http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2

Uses 0x03 which does work, so this means not setting bit 3 of r10 which
sets: "Enable Real H/W Resolution In Absolute mode"

Which will result in half the x and y resolution we get with that bit set,
so simply not setting it everywhere is not a solution. We've been unable to
find a way to identify touchpads where setting the bit will fail, so this
patch uses a dmi based blacklist for this.

Input: elantech - add support for newer elantech touchpads

2014-04-23T05:56:41+00:00

Newer elantech touchpads are not recognized by the current driver, since it
fails to detect their firmware version number. This prevents more advanced
touchpad features from being usable such as two-finger scrolling. This
patch allows newer touchpads to be detected and be fully functional. Tested
on Sony Vaio SVF13N17PXB.

Input: synaptics - add min/max quirk for ThinkPad T431s, L440, L540, S1 Yoga and X1

2014-04-20T05:44:21+00:00

We expect that all the Haswell series will need such quirks, sigh.

The T431s seems to be T430 hardware in a T440s case, using the T440s touchpad,
with the same min/max issue.

The X1 Carbon 3rd generation name says 2nd while it is a 3rd generation.

The X1 and T431s share a PnPID with the T540p, but the reported ranges are
closer to those of the T440s.

HdG: Squashed 5 quirk patches into one. T431s + L440 + L540 are written by me,
S1 Yoga and X1 are written by Benjamin Tissoires.

Hdg: Standardized S1 Yoga and X1 values, Yoga uses the same touchpad as the
X240, X1 uses the same touchpad as the T440.
