Elantech touchpad (HID over I2C): any work planned?

[Nikola Lečić]

Actually, I was too optimistic in my reporting. The new driver worked
for me just once -- until reboot. After that, I couldn't get the
touchpad working again. After usual dmesg lines, any movement on
touchpad produces endless repeating of this message:

  kernel:	iichid0: no data received

and no effect on cursor.

Scroll down for more bad info.

Unfortunately, the driver breaks suspend for me (which works just fine
without it). After 'acpiconf -s3' laptop hangs on ttyv1 with quickly
blinking mouse cursor and these lines:

...
<6>[drm] GPU HANG: ecode 9:1:0xfffffffe, reason: Hang on bcs0, action:
reset 
drmn0: Failed to idle engines, declaring wedged!

(This is with /boot/modules/i915kms.ko.)

Thanks, but for now two-finger scrolling simply doesn't work for me.
I'll investigate further when I get responsive touchpad again.

I can't create an account; it says: "Email address must be
@freebsd.org" (I don't have one).
