2008-09-16Input: bcm5974 - switch back to normal mode when closingHenrik Rydberg
Staying in multi-touch mode after closing the device sometimes makes the keyboard drop keys or repeat keys irratically. The conjecture is that some internal buffer starts to overflow, resulting in undefined behavior. Switching back to normal mode when closing the device makes the problem go away.

2008-09-04Input: bcm5974 - add BTN_TOUCH event for mousedev benefitHenrik Rydberg
The mousedev driver requires the use of BTN_TOUCH events to process ABS_X and ABS_Y events properly, which is what is needed for the bcm5974-based apple computers to have a functional pointer out-of-the-box.

2008-09-04Input: bcm5974 - improve finger tracking and countingHenrik Rydberg
The problem of finger tracking, i.e., when to switch focus from one finger to another on the trackpad, has been improved by utilizing more information from the bcm5974 chip output. This results in less pointer hopping when many fingers are on the trackpad. In addition, a finger counting method based on pressure information from all fingers is introduced. Together with a pressure hysteresis window, this yields a more stable counting of the number of fingers on the trackpad.

2008-08-08Input: bcm5974 - add driver for Macbook Air and Pro Penryn touchpadsHenrik Rydberg
This driver adds support for the multitouch trackpad on the new Apple Macbook Air and Macbook Pro Penryn laptops. It replaces the appletouch driver on those computers, and integrates well with the synaptics driver of the Xorg system.
