Subject: [PATCH 00/10] power: supply: Charger-manager improvements
Date: Thu, 14 May 2020 16:04:25 -0700	[thread overview]
Message-ID: <BN6PR04MB06603115D277DF264D9380E8A3BC0@BN6PR04MB0660.namprd04.prod.outlook.com> (raw)

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.
