Charger-manager is a virtual driver for unifying chargers, fuel gauges,
extcon devices, and a thermal device into a battery management system.
Unfortunately, it has been broken since commit 830ae442202e ("extcon:
Remove the deprecated extcon functions") when the extcon internal API
was changed but some drivers were not updated. Additionally, it had
some race conditions and was unnecessarily complex.
A number of these patches come from a Tizen git tree(1); they have been
rebased and the commit messages cleaned up.
These changes have been tested on a couple of first-gen Galaxy S devices
based on s5pv210 with a modified max8998 driver so that a charger
regulator is exposed. In addition to the max8998, this hardware has
a max17040 fuel gauge, fsa9480 extcon, and a generic thermal resistor
for temperature sensing.
