Igor FilatovandBastien Nocera ae1b10dba8 elan: Fix frame leak in elan_submit_image 2019-08-05 18:43:04 +02:00
Igor FilatovandBastien Nocera 8553f2e41c elan: Send stop cmd and recalibrate after each capture 
This seems to fix the lock-up issue with 0903

Igor FilatovandBastien Nocera 4ff97e7cbd elan: Increase bz3 threshold to 24 
Based on experience. Values more than 24 seem to work just after
enrollment, but it becomes very hard to verify in a day or so.

Igor FilatovandBastien Nocera 75fe328f64 elan: Don't rotate frames on 0x0c03 
There has been a report that a 0x0c03 was installed straight (other
readers so far have produced images that are 90 degrees rotated). There
is no way for the dirver to know how a device is installed, so for now just
make an exception.

Igor FilatovandBastien Nocera b28b006d61 elan: Use IMGDEV_STATE_* events instead of pre-set capture path 2018-08-10 13:45:29 +02:00
Igor FilatovandBastien Nocera c3b1c982bc elan: Set max frame height to 50, add note about performance 
Frame height is a loosely experience-backed guesstimation. 50 seems to be
a good middle ground between swipe speed and quality.

Igor FilatovandBastien Nocera b098399bbc elan: Support 0x0c01~0x0c33 2018-08-10 13:45:29 +02:00
Igor FilatovandBastien Nocera 65bbdff3fc elan: Stop doing sensor reset, change calibration and frame logic 
Sensor reset code has been removed because it is not needed during normal
operation.

Calibration and frame processing logic has been improved according to
recommendations from Elantech.

Igor FilatovandBastien Nocera fba3e682ea elan: Remove supported devices from udev whitelist 2018-08-09 14:45:15 +02:00
Igor FilatovandBastien Nocera bccff4ffef elan: Change command structs, support more devices 
Make each command a separate struct to get finer control over which
commands are called on which devices. Update ssm's accordingly. Add
sensor_reset and fuse_load commands.

Support 0x0903, 0x0c03, 0x0c16, 0x0c1a, 0x0c26
