Revert "Input: appletouch - fix integer overflow issue"

2010-08-09T03:48:08Z

This reverts commit 04b4b88cca0ebe3813b4b6f014fb6a0db380b137. While the original problem only caused a slight disturbance on the edge of the touchpad, the commit above to "fix" it completely breaks operation on some other models such as mine. We'll sort this out separately, revert the patch for now. Signed-off-by: Benjamin Herrenschmidt

USB: rename usb_buffer_alloc() and usb_buffer_free() users

2010-05-20T20:21:38Z

For more clearance what the functions actually do, usb_buffer_alloc() is renamed to usb_alloc_coherent() usb_buffer_free() is renamed to usb_free_coherent() They should only be used in code which really needs DMA coherency. All call sites have been changed accordingly, except for staging drivers. Signed-off-by: Daniel Mack Cc: Alan Stern Cc: Pedro Ribeiro Signed-off-by: Greg Kroah-Hartman

Input: appletouch - fix integer overflow issue

2010-03-11T08:00:56Z

When reading data from Geyser 2 touchpads used on post Oct 2005 Apple PowerBooks the driver was casting X and Y coordinates values to 'signed char'. Testing on one of such PowerBooks I have noticed that touchpad always generates positive values, but some of them are greater that 127, and thus, when cast to 'signed char' being interpreted as a negative. Such bigger values have been observed infrequently, closer to the edges of a touchpad, so the problem was not very visible. Nevertheless, the patch would potentially improve touchpad driver accuracy.

Input: appletouch - improve finger detection

2009-06-03T14:37:54Z

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. Signed-off-by: Jeremy Huddleston Signed-off-by: Dmitry Torokhov

Input: appletouch - fix DMA to/from stack buffer

2009-04-28T16:34:13Z

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. Signed-off-by: Bob Copeland Reviewed-by: Johannes Berg Signed-off-by: Dmitry Torokhov

Input: appletouch - driver refactoring

2008-10-29T04:28:30Z

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).
