user/sven/linux.git/drivers/input/mouse/elantech.c, branch v3.2.19

Input: elantech - adjust hw_version detection logic

2011-11-10T05:19:47Z

This patch fixes some v3 hardware (fw_version: 0x150500) wrongly detected as v2 hardware. Reported-by: Marc Dietrich Signed-off-by: JJ Ding Tested-By: Marc Dietrich Acked-by: Éric Piel Signed-off-by: Dmitry Torokhov

Input: psmouse - switch to using dev_*() for messages

2011-10-11T01:28:16Z

This will ensure our reporting is consistent with the rest of the system and we do not refer to obsolete source file names. Reviewed-by: Wanlong Gao Reviewed-by: JJ Ding Reviewed-by: Daniel Kurtz Signed-off-by: Dmitry Torokhov

Input: elantech - remove module parameter force_elantech

2011-09-21T05:46:28Z

This essentially reverts commit f81bc788ff91d4efd4baf88b2c29713838caa8e5. With recent work on elantech driver, I believe we now have complete support for all elantech touchpads. So remove this hack. Signed-off-by: JJ Ding Reviewed-by: Éric Piel Signed-off-by: Dmitry Torokhov

Input: elantech - better support all those v2 variants

2011-09-21T05:46:27Z

V2 hardware has many variants. This patch adddresses two issues: - some model also has debounce packets, but with a different signature than v3. Now we just check debounce for all v2 hardware. - due to different scanning methods the hardware uses, x and y ranges have to be calculated differently. And for some specific versions, we can just see them as custom-made, so set {x, y} the same values as Windows driver does.

Input: elantech - add v4 hardware support

v4 hardware is a true multitouch capable touchpad (up to 5 fingers). The packet format is quite complex, please see protocol document for reference. Signed-off-by: JJ Ding Signed-off-by: Dmitry Torokhov

Input: elantech - add v3 hardware support

2011-09-09T17:34:58Z

v3 hardware's packet format is almost identical to v2 (one/three finger touch), except when sensing two finger touch, the hardware sends 12 bytes of data. Signed-off-by: JJ Ding Acked-by: Daniel Kurtz Acked-by: Éric Piel Signed-off-by: Dmitry Torokhov

Input: elantech - packet checking for v2 hardware

2011-09-09T17:34:50Z

For v2 hardware, there is no real parity check, but we can still check some constant bits for data integrity. Also rename elantech_check_parity_v1 to elantech_packet_check_v1 to make these packet checking function names consistent.

Input: elantech - use firmware provided x, y ranges

With newer hardware, the touchpad provides range info. Let's use it. Signed-off-by: JJ Ding Acked-by: Daniel Kurtz Acked-by: Éric Piel Signed-off-by: Dmitry Torokhov

Input: elantech - get rid of ETP_2FT_* in elantech.h

2011-09-09T17:34:31Z

For two finger touches the coordinate of each finger gets reported separately but with reduced resolution. With this change, we now have the same range for ST and MT data and scale MT data because it has lower resolution to match ST.
