* Input: mark serio and i8042 as suspended when hibernating tooThadeu Lima de Souza Cascardo2009-07-072-6/+8
| | | | | | | | | | | | | Serio ports are not being restarted any longer because resume operations after hibernate do nothing, since the device has not been marked as suspended. This happens because suspend is only considering the SUSPEND event but not the FREEZE event. Note that this driver has still to migrate to dev_pm_ops, but this fixes this particular bug now.

* Input: add support for generic GPIO-based matrix keypadEric Miao2009-06-293-2/+465
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Original patch by Marek Vasut, modified by Eric in: 1. use delayed work to simplify the debouncing 2. combine col_polarity/row_polarity into a single active_low field 3. use a generic bit array based XOR algorithm to detect key press/release, which should make the column assertion time shorter and code a bit cleaner 4. remove the ALT_FN handling, which is no way generic, the ALT_FN key should be treated as no different from other keys, and translation will be done by user space by commands like 'loadkeys'. 5. explicitly disable row IRQs and flush potential pending work, and schedule an immediate scan after resuming as suggested by Uli Luckas 6. incorporate review comments from many others Patch tested on Littleton/PXA310 (though PXA310 has a dedicate keypad controller, I have to configure those pins as generic GPIO to use this driver, works quite well, though), and Sharp Zaurus model SL-C7x0 and SL-C1000.

| | | | | | | | | | | | | The touchscreen works in two modes, wait trigger mode and auto-semi mode. The device starts in wait trigger mode and waits until pressure is detected, then device sets WT_INT bit and raises an interrupt. The driver should put the device into auto-semi mode and prepare for reading first X and then Y coordinates. When coordinate data is ready the driver sets ADC_INT bit and raises interrupt again.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When userspace sets effect->u.rumble.strong_magnitude to 0x8001 or larger, ml_combine_effects() would always return strong_magnitude 0xffff. Problem is that 'gain' is passed in as signed integer. Multiplying magnitude (__u16) with gain (int) causes magnitude read as signed and results negative value (with magnitude > 0x8000). This signed integer is then divided and value, still negative, converted to 32bit unsigned integer. Finally checking combine overflow min(new+old, 0xffff) gives out 0xffff. Fix is to simply change 'gain' to unsigned int.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This patch adds a multi-touch (MT) protocol which allows drivers to report details for an arbitrary number of fingers. The driver sends a SYN_MT_REPORT event via the input_mt_sync() function when a complete finger has been reported. In order to stay compatible with existing applications, the data reported in a finger packet must not be recognized as single-touch events. In addition, all finger data must bypass input filtering, since subsequent events of the same type refer to different fingers. A set of ABS_MT events with the desired properties are defined. The events are divided into categories, to allow for partial implementation. The minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked. If the device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size of the approaching finger. Anisotropy and direction may be specified with ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and ABS_MT_ORIENTATION. Devices with more granular information may specify general shapes as blobs, i.e., as a sequence of rectangular shapes grouped together by a ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE may be used to specify whether the touching tool is a finger or a pen. Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
