linux.git/drivers/input/mouse/elantech.c, branch v2.6.39

Input: return -ENOMEM in select drivers when memory allocation fails

2010-10-13T14:49:23+00:00

Instead of using -1 let's start using proper error codes.

Input: elantech - report position also with 3 fingers

2010-08-06T06:53:22+00:00

The 6-byte protocol supports reporting the position when three fingers
are pressed, exactly like when one finger is pressed. Report this.

In addition, it is also distinguishes between 3 and 4 fingers pressed.

Input: elantech - discard the first 2 positions on some firmwares

2010-08-06T06:52:29+00:00

According to the Dell/Ubuntu driver, what was previously observed as
"jumpy cursor" corresponds to the hardware sending incorrect data for
the first two reports of a one touch finger. So let's use the same
workaround as in the other driver. Also, detect another firmware
version with the same behaviour, as in the other driver.

Input: elantech - relax signature checks

2010-05-19T17:15:13+00:00

Apparently there are Elantech touchpads that report non-zero in the 2nd byte
of their signature. Adjust the detection routine so that if 2nd byte is
zero and 3rd byte contains value that is not a valid report rate, we still
assume that signature is valid.

Input: elantech - use all 3 bytes when checking version

2010-05-13T07:43:19+00:00

Apparently all 3 bytes returned by ETP_FW_VERSION_QUERY are significant
and should be taken into account when matching hardware version/features.

Input: elantech - ignore high bits in the position coordinates

2010-05-04T06:35:11+00:00

In older versions of the elantech hardware/firmware those bits always
were unset, so it didn't actually matter, but newer versions seem to
use those high bits for something else, screwing up the coordinates
we report to the input layer for those devices.

Input: elantech - allow forcing Elantech protocol

2010-05-04T06:34:33+00:00

Apparently hardware vendors now ship elantech touchpads with different version
magic. This options allows for them to be tested easier with the current driver
in order to add their magic to the whitelist later.
