Subject: [PATCH v3] synaptics: Add min/max quirk for ThinkPad T431s, L440,
|
|
|
69523a2 |
L540, S1 Yoga and X1
|
|
|
e58a971 |
|
|
|
e58a971 |
We expect that all the Haswell series will need such quirks, sigh.
|
|
|
e58a971 |
|
|
|
e58a971 |
The T431s seems to be T430 hardware in a T440s case, using the T440s touchpad,
|
|
|
e58a971 |
with the same min/max issue.
|
|
|
e58a971 |
|
|
|
e58a971 |
The X1 Carbon 3rd generation name says 2nd while it is a 3rd generation.
|
|
|
e58a971 |
|
|
|
e58a971 |
The X1 and T431s share a PnPID with the T540p, but the reported ranges are
|
|
|
e58a971 |
closer to those of the T440s.
|
|
|
e58a971 |
|
|
|

HdG: Squashed 5 quirk patches into one. T431s + L440 + L540 are written by me,
|
|
|
e58a971 |
S1 Yoga and X1 are written by Benjamin Tissoires.
|
|
|
e58a971 |
|
|
|
69523a2 |
Hdg: Standardized S1 Yoga and X1 values, Yoga uses the same touchpad as the
|
|
|
69523a2 |
X240, X1 uses the same touchpad as the T440.
