Subject[PATCH v5 0/8] Input: elantech: add support for newer hardware
Hi Lists,

This is a series of patches to add support for newer generations of ELAN

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.

Please take a look at patch #8, which adds support for the latest touchpads from ELAN.
It 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.

Changes since v4:
- patch #8: fix a typo (pressure, spotted by Éric)
- patch #8: add _v4 suffix for functions introduced in this patch (suggested by Éric)
- patch #8: simplify set_range switch for case 3 and case 4 (suggested by Éric)

JJ Ding (8):
Input: elantech - correct x, y value range for v2 hardware
Input: elantech - get rid of ETP_2FT_* in elantech.h

Input: elantech - remove ETP_EDGE_FUZZ_V2
Input: elantech - packet checking for v2 hardware
Input: elantech - clean up elantech_init
Input: elantech - add v3 hardware support
Input: elantech - add v4 hardware support
