Hi!
In 4.4, n900 battery charging works. If indicator is turned off, it
stays off, and if I select 1.8A charge, it sticks. (There may be
problems after system suspend and resume. But normal operation seems
to be pretty reliable).
In 4.5-rc0 (7fdec82af6a9e190e53d07a1463d2a9ac49a8750) battery charging
works for few hours. But then indicator (yellow light on 3color LED)
turns back on, and if I ask for 1.8A charge, it goes back to .1A,
discharging battery.
Any ideas?
Best regards,
Pavel

Maybe a side-effect of isp1704 driver actually doing what was
intended, which is is 88025632515a ("power: isp1704_charger: Fix
isp1704_write()").
P.S.: No need to Cc me two times and when you update your
script/contacts, please use sre at kernel.org :)

Hmm. It looks like 7fdec82af6a does not yet contain 88025632515a. Let
me try to add that fix, instead...

Address book updated :-).

Right, your checkout does not contain the power supply
pull request. I think it's unlikely, that the patch will
fix your issue.
Since there are no other power supply changes between 4.4 and your
checkout, the next most likely candidate is the usb tree (which has
been merged before the commit you mentioned).

Hm... right, bq2415x driver does not have support for suspend/resume.
Before suspend registers should be stored and after resume restored,
plus check charger auto detection.

Look into bq24150a sysfs node what changes. Also if there is something
in dmesg.

Hmm, seems like I can't reproduce that any more. I now noticed that if
I suspend machine it auto-resumes quickly, so maybe suspend was
responsbile. I'll try running 4.5-rc0 for a while...
Thanks,
Pavel
