From: Daniel Kurtz <djkurtz@xxxxxxxxxxxx> Hello, This patch set (against next) is intended to add support for synaptics "image sensor" touchpads. Patches 1-8 clean up the current driver slightly and prepare for the image sensor patches which follow. Patches 9-11 add up to 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" (which 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". Unfortunately, the limitations of the Synaptics PS/2 protocol make it difficult to keep track of which two fingers are being reported at any given time. Patch 12 adds up to 5 finger support. In fact, the image sensor touchpads actually track 5 fingers while reporting just 2 finger positions. This patch tracks which fingers are being reported, and passes them up to userspace using 5 MT-B slots. These patches are similar to, and inspired by, a similar patchset recently submitted by Derek Foreman and Daniel Stone. However, it is not directly built upon, nor is it compatible with, those patches.
