  On some platforms the touchpad relies on pinctrl devices to provide GPIO 
interrupt, but in 3.19.0 pinctrl-cherryview doesn't support suspend well and 
will lose the config after suspend/resume, then touchpad can't be used.

  [Fix]
  There's a commit in 4.0-rc1 to add suspend/resume for pinctrl-cherryview:

[Luis Henriques]

I believe that the best thing to do is to close this bug and open a new
one with the information in comment #3.  Phidias, could you please do
that? (Feel free to assign that bug to me, or at least to subscribe me).

[Kernel-packages] [Bug 1518855] Re: Backport better suspend/resume function for pinctrl-cherryview

[Phidias]

This  SRU patch fix the problem that pinctrl-cherryview can't suspend which
make i2c touchpad unusable after S3.

But when I'm doing SRU verification I discovered that in about 1/5 time of S3,
the following error occurs:

[ 731.748182] i2c_hid i2c-DLL0725:01: i2c_hid_hwreset
  ...
  ...
[ 736.749017] i2c_hid i2c-DLL0725:01: failed to reset device.
[ 736.750015] dpm_run_callback(): i2c_hid_resume+0x0/0xe0 [i2c_hid] returns -61
[ 736.750022] PM: Device i2c-DLL0725:01 failed to resume: error -61

and the touchpad dies, which didn't happen before with 60 runs of S3
test[1].

It appears to be a race condition in i2c-hid, and there's already a fix for 
this issue:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9a327405014f4ef4cdad67a0686db82b9f23c62c,
I've built a kernel to test this fix, and it works, no more error -61, and it 
pass 10/10 so far.

Please advice the next step, and sorry for the inconvenience.

[1]: The error message showed up in the test, but the touchpad still
works under i2c so was not considered critical.

[Luis Henriques]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
vivid' to 'verification-done-vivid'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!
