Hi Lists,
This is a series of patches to add support for newer generations of ELAN touchpad.
Patches #1~#6 are essentially fixes and cleanups that pave the way for patch #7 and patch #8, which really adds code for v3 and v4 hardware.
Any comments, suggestoins are welcome.
Note: Please review patch #8, which adds support for the latest touchpads from ELAN. This is a true multi-touch capable touchpad that can track up to 5 fingers. Support is implemented using MT-B protocol. I used synaptics and multitouch X driver to test this driver, both worked fine.
Thank you very much.
Changes since v1: - drop EC workaround patch. - add patch #2, make ST and MT have the same range, as Dmitry suggested. - add patch #4, remove ETP_EDGE_FUZZ_V2, as Éric suggested. - rename all packet checking functions so they are consistent. - some code cleanup, and don't report ABS_[XY] when fingers == 0, as Seth suggested. - add document for v3 debounce, and now check debounce in elantech_packet_check_v3.
Changes since v2: - fix v3 hardware packet checking (reported by Seth and fix by Dmitry.)
Changes since v3: - fix a tiny style problem (useless space on end-of-line, reported by Seth) - v3 hardware can track 2 fingers well, so do not set INPUT_PROP_SEMI_MT on v3 (As suggested earlier by Éric.) - add patch #8, which adds support for v4 hardware.
