Hi Lorenzo,
I wanted to check if your newest fix
9d6408433019bfae15e2d0d5f4498c4ff70b86c0 resolved my problem but it
looks like it breaks i2c devices on yoga 910 at all.
One thing that I see in dmesg is:
[ 5.443582] i2c_designware i2c_designware.1: controller timed out
[ 5.443601] i2c_hid i2c-SYNA2B31:00: hid_descr_cmd failed
[ 6.595650] i2c_designware i2c_designware.2: controller timed out
[ 6.595673] i2c_hid i2c-ITE8186:00: hid_descr_cmd failed
More details you can see in mentioned isssue.
BTW maybe you have an idea what is the root of my problem. I've attached
i2c_hid logs for previous version.
Commit 9d6408433019 ("i2c: designware: don't infer timings described
by ACPI from clock rate") had issue with uninitialized variables that
show up when ACPI platform doesn't provide timing parameters for the
I2C but fortunately that was caught quickly.
Could you try does a patch from Jan Kiszka fix the issue you are seeing?
https://lkml.org/lkml/2017/5/22/24
I've tried and it looks like it removed this regression but still all of
this changes didn't helped for my problem with missing changes from
accelometer.
Maybe you can take a look at isc_hid log after all of those changes:
https://bugzilla.kernel.org/attachment.cgi?id=256651 and tell me if you
see something worrying?
BTW sorry for invalid mailing list - changed
Cheers,
Arek
