Hello,

-For v3:
- Merged Patch 5 & 6:
- BTN_TOOL_*TAP always reports correct number of fingers.
- During certain ambiguous number-of-finger-transitions, there may be less
- than 2 valid MT-B slots, even if the BTN_TOOL_*TAP value indicates two or
- more fingers are present on the pad.
+For v4:
+ Patch 4 & 7:
+ Per Henrik: Do not report synaptics 'w' as ABS_MT_TOUCH_MAJOR. This has
+ the nice side affect of cleaning up slot reporting.
+
+ Patch 6 (new):
+ Per Chase: Document 'report more touches than slots' behavior.

This patch set (against next) is intended to add support for synaptics

Patches 1-3 clean up the current driver slightly and prepare for the image
sensor patches which follow.
-Patches 4-6 add 3 finger support for image sensor touchpads.
+Patches 4-7 add 3 finger support for image sensor touchpads.
Image sensors do not suffer from the finger tracking issues that plagued
the earlier "profile sensors", and which required the invention of "semi-mt"
(Semi-mt reports a bounding box around two fingers instead of the fingers
themselves). Instead, the image sensors report the actual positions of two
fingers using the same "Advanced Gesture Mode". This driver uses two MT-B slots
to report these two fingers to userspace. In addition, it will also report
-the total number of fingers using BTN_TOOL_*TAP EV_KEY events.
+the total number of fingers using BTN_TOOL_*TAP EV_KEY events. This behavior
+is documented in the multi-touch-protocol document.
Userspace drivers should be aware that the number of fingers reported via
BTN_TOOL_*TAP can be greater than the total number MT-B slots with non-negative
