Input: appletouch - improve finger detection

2009-06-03T14:37:54+00:00

The appletouch driver is prone to reporting multiple fingers when only
one is pressing.  The appletouch driver queries an array of pressure
sensors and counts local maxima in pressure to determine the number of
fingers.  It just does this on the raw values, so a data stream like:

0 100 250 300 299 300 250 100 0

actually registers as 2 fingers.

This patch updates the logic to ignore small dips in pressure that are
less than the threshold.

Input: appletouch - fix DMA to/from stack buffer

2009-04-28T16:34:13+00:00

CONFIG_DMA_API_DEBUG spotted an instance of appletouch using
an array on the stack as a DMA buffer for certain hardware.
Change it to use a kmalloc()ed buffer instead.

Input: appletouch - driver refactoring

2008-10-29T04:28:30+00:00

The appletouch driver has grown up from supporting only a couple of
touchpads into supporting many touchpads, which can have different
number of sensors, different aspect ratios etc.

This patch cleans up the current driver code and makes it easy to
support the features of each different touchpad.

As a side effect, this patch also modifies the 'Y' multiplication factor
of the 'geyser3' and 'geyser4' touchpads (found on Core Duo and Core2
Duo MacBook and MacBook Pro laptops) in order to make the touchpad
output match the aspect ratio of the touchpad (Y factor changed from 43
to 64).

Input: appletouch - implement reset-resume logic

2008-06-17T15:56:55+00:00

On some boxes the touchpad needs to be reinitialized after resume to make
it function again. This fixes bugzilla #10825.
