2011-08-23Input: synaptics - add image sensor supportDaniel Kurtz
Synaptics makes (at least) two kinds of touchpad sensors: * Older pads use a profile sensor that could only infer the location of individual fingers based on the projection of their profiles onto row and column sensors. * Newer pads use an image sensor that can track true finger position using a two-dimensional sensor grid. Both sensor types support an "Advanced Gesture Mode": When multiple fingers are detected, the touchpad sends alternating "Advanced Gesture Mode" (AGM) and "Simple Gesture Mode" (SGM) packets. The AGM packets have w=2, and contain reduced resolution finger data The SGM packets have w={0,1} and contain full resolution finger data Profile sensors try to report the "upper" (larger y value) finger in the SGM packet, and the lower (smaller y value) in the AGM packet. However, due to the nature of the profile sensor, they easily get confused when fingers cross, and can start reporting the x-coordinate of one with the y-coordinate of the other. Thus, for profile sensors, "semi-mt" was created, which reports a "bounding box" created by pairing min and max coordinates of the two pairs of reported fingers. Image sensors can report the actual coordinates of two of the fingers present. This patch detects if the touchpad is an image sensor and reports finger data using the MT-B protocol. NOTE: This patch only adds partial support for 2-finger gestures. The proper interpretation of the slot contents when more than two fingers are present is left to later patches. Also, handling of 'number of fingers' transitions is incomplete.

2011-08-23Input: synaptics - refactor agm packet parsingDaniel Kurtz
When a Synaptics touchpad is in "AGM" mode, and multiple fingers are detected, the touchpad sends alternating "Advanced Gesture Mode" (AGM) and "Simple Gesture Mode" (SGM) packets. The AGM packets have w=2, and contain reduced resolution finger data. The SGM packets have w={0,1} and contain full resolution finger data. Refactor the parsing of agm packets to its own function, and rename the synaptics_data.mt field to .agm to indicate that it contains the contents of the last agm packet.

2011-08-23Input: synaptics - refactor y inversionDaniel Kurtz
Synaptics touchpads report increasing y from bottom to top. This is inverted from normal userspace "top of screen is 0" coordinates. Thus, the kernel driver reports inverted y coordinates to userspace. This patch refactors this inversion.

Currently, battery drivers also use poll_sample() provided by the wm97xx-core but this code always checks if the pen is down. Mark the channels which really need this (i.e. for the touchscreen) with the PEN_DOWN bit, and skip the checks otherwise. Now, the battery channels can always be read.

2011-07-04Input: wm97xx - refactor channel selection in poll_sample()Wolfram Sang
The current implementation of poll_sample() has the problem that one of its arguments, the channel to be selected, differs from wm9713 to other variants. This parameter gets passed to the (currently unused) mach-specific functions pre_sample() and post_sample() which thus have to deal with codec-specific differences. Refactor the routine so that the argument to poll_sample() is generic for all codecs and do necessary conversions only in the codec-specific driver. The outcome even uses less code and removes the non-standard use of the PEN_DOWN bit to mark the AUX-channels.
