Igor Filatov 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 Filatov 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 Filatov b28b006d61 elan: Use IMGDEV_STATE_* events instead of pre-set capture path 2018-08-10 13:45:29 +02:00
Igor Filatov 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 Filatov b098399bbc elan: Support 0x0c01~0x0c33 2018-08-10 13:45:29 +02:00
Igor Filatov 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 Filatov 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

Bastien Nocera 2e035a7f45 lib: Make fpi_ssm opaque for drivers
We shouldn't access fpi_ssm struct fields directly in drivers, so add
accessor and setter functions for the common uses.

Bastien Nocera 19dfb138a6 drivers: Use new drivers_api.h in drivers 2018-05-29 13:34:18 +02:00
Bastien Nocera 994061af44 drivers: Simplify headers
Remove all the headers already included through "fp_internal.h" such as
<libusb.h> and <errno.h>, include "assembling.h" and "driver_ids.h" there
as well to avoid doing it in (almost) every driver.

Bastien Nocera 32fcfde86b lib: Use GLib and libusb directly for debug output
Use GLib internally to output debug information, and tell about
libusb's LIBUSB_DEBUG envvar for libusb debug.

fp_set_debug() is now a no-op.

Bastien Nocera 363a1b3371 lib: Replace empty fp_dbg() calls
GLib won't like them, so use G_DEBUG_HERE() instead.
