Subject: [PATCH 0/3] power: supply: bq24735: handle AC adapter absence

Hi!

There is provision in the driver for handling the case where the
chargers are not responding to i2c requests when the AC adapter
is absent. I think this has been used by some Tegra boards that
leave the charger handling to some other component and that only
wants the kernel to be aware of the charging status for reporting
(or whatever).

However, in my case, the kernel should handle configuration and
enable/disable the charging, but this is not working very well
when the charger disappears (and is reset) on AC adapter absence.

This series fixes the issues I have found in this area so that I
can boot without AC adapter and have the correct charging config
every time I do attach the AC adapter.

Cheers,
Peter
