linux/drivers/input/mouse/alps.c, branch v3.17-rc3

Input: alps - Rushmore and v7 resolution support

2014-07-31T05:53:20Z

Add support for querying the physical size from the touchpad for Rushmore and v7 touchpads, and use that to tell userspace the device resolution. Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov

Input: alps - add support for v7 devices

2014-07-26T21:03:20Z

Such as found on the new Toshiba Portégé Z30-A and Z40-A.

Input: alps - change decode function prototype to return an int

2014-07-26T21:03:18Z

So that decode functions can return a failure when appropriate. Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov

Input: alps - report 2 touches when we've > 2 fingers

2014-07-26T21:03:18Z

If we detect more then 2 fingers report 2 touches, rather then only reporting the upper left corner of the bounding box. Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov

Input: alps - add an alps_report_semi_mt_data function

2014-07-26T21:03:17Z

Move all the semi-mt specific handling shared between the v3 and v4 handling code to a common helper function. Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov

Input: alps - use single touch data when v3 mt data contains only one finger

2014-07-26T21:03:17Z

For v3 protocol devices, use the more accurate single touch data when the mt data contains only one finger. Note the mt data reporting a finger count of 1 should never happen, but better safe then sorry. This brings the v3 bitmap handling in line with what the v4 code does, allowing to factor out the common bits into a helper function. Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov

Input: alps - use standard contact tracking instead of DIY

2014-07-26T21:03:16Z

When there are 2 fingers on the pad we don't know which one is which, so use input_mt_assign_slots to make sure the right set of coordinates ends up in the right slot. Besides ensuring things end up in the right slot, this also results in a nice cleanup, since sync_frame also handles non mt position and btn_touch reporting.

Input: alps - use struct input_mt_pos to track coordinates

2014-07-26T21:03:16Z

This is a preparation patch for switching the DIY mt handling to using input_mt_assign_slots && input_mt_sync_frame. struct alps_fields is quite large, so while making changes to almost all uses of it lets put it in our priv data instead of on the stack. Having it in our priv data also allows using it directly for storing values which need to be cached, rather then having separate x, y, z, fingers, etc. copies in our priv data.

Input: alps - process_bitmap: round down when spreading adjescent fingers over 2 points

2014-07-26T21:03:15Z

This fixes 2 fingers at the same height or width on the touchpad getting reported at different y / x coordinates. Note num_bits is always at least 1. Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov
