Hi Sebastian, Marek,

I have been working on getting a Lenovo Yoga Tab 3 Pro (YT3-X90F) to
work with the mainline kernel. This tablet has 2 batteries with
2 bq25892 chargers both connected to a single Micro-USB connector.

Supporting the 2 charger board also requires the recent HiZ mode patches
from Marek, to avoid merging order problems / conflicts I have included
a copy of Marek's series here so this series obsoletes the:

[PATCH 1/2] power: supply: bq25890: Factor out chip state update
[PATCH 2/2] power: supply: bq25890: Add HiZ mode support
[PATCH v2 1/2] power: supply: bq25890: Factor out chip state update
[PATCH v2 2/2] power: supply: bq25890: Add HiZ mode support

patches from Marek.

While working on adding support for this I also noticed some generic issues
with the bq25890 driver currently in linux-power-supply/for-next and I also
have some fixes to the HiZ support on top of Marek's support.

So this entire series consist of 4 parts:

1. Patches 1-3:

Generic bugfixes for the bq25890 charger in its current state
in linux-power-supply/for-next. Patch 1/10 fixes an actual regression on
some boards with for-next so that one definitely needs to go to 6.2.
The other 2 fixes can go to either 6.2 or 6.3

2. Patches 4-5:

Marek's HiZ support work, thank you Marek.

3. Patches 6-7:

Some fixes / improvements from me to Marek's HiZ support.

4. Patch 8-10:

The actual support for boards with 2 chargers.

Stating the obvious here: given where we are in the cycle I expect
parts 2-4 / patches 4-10 to all be 6.3 material. 

Regards,

Hans
