power: supply: max8903: Absorb pdata header

2021-01-12T22:23:49+00:00

The platform data header is not included by any other file in
the kernel but the driver itself. Decomission the stand-alone
header and absorb it into the driver itself.

power: supply: generic-adc-battery: Use GPIO descriptors

2020-11-30T01:42:42+00:00

This driver uses platform data to pass GPIO lines using the
deprecated global GPIO numbers. There are no in-tree users
of this platform data.

Any out-of-tree or coming users of this driver can easily be
migrated to use machine descriptor tables as described in
Documentation/driver-api/gpio/board.rst
section "platform data".

power: supply: bq27xxx: add support for TI bq34z100

2020-10-01T22:01:42+00:00

Add support for new device: the TI bq34z100-G1, a Wide Range Fuel Gauge
for Li-Ion, PbA, NiMH, and NiCd batteries.  The device shares a lot with
other models, although it has its own differences requiring new quirks.

This patch was tested on a system equipped with NiMH batteries.

power: supply: charger-manager: Update extcon functions

2020-08-28T17:27:45+00:00

In commit 830ae442202e ("extcon: Remove the deprecated extcon functions")
the function extcon_register_interest became a no-op returning an error,
leading to non-functional behaviour in charger-manager.

Additionally, a translation table is needed between the text representation
of the extcon cable names and their IDs is needed.  In order to retain DT
compatibility, TA and CHARGE-DOWNSTREAM are added as they were present up
until commit 11eecf910bd8 ("extcon: Modify the id and name of external
connector")

power: supply: charger-manager: Make decisions focussed on battery status

2020-08-28T17:27:45+00:00

cm_monitor(), where charging management starts, checks various charging
condition sequentially to decide next charging operation. However, as it
follows sequential process, cascaded if statements, it does some
jobs which have already done in the previous stage. This results in a
delay in decision making. Moreover, starting point of charging is spread
all around which makes maintain code and debugging difficult.

Both of the problems mentioned above become clean if it manages battery
charging focusing on battery status not following sequential condition
checking.  Now, cm_monitor() moves battery state diagram and does the
optimal operation for current state. As a result, it reduces whole
monitoring time almost in half.

power: supply: charger-manager: Remove cm_notify_event function

2020-08-28T17:03:24+00:00

cm_notify_event() was introduced to get an event associated with the
battery status externally (ie in board files), but no one ever used it.
Moreover it makes charger manager driver more complicated. Drop the
function and all data related to it to simplify the driver.

power: supply: smb347-charger: Drop pdata support

2020-08-28T13:33:10+00:00

There are no platforms using the pdata support, so let's
drop it to simplify the driver.

power: supply: gpio-charger: Convert to GPIO descriptors

2020-08-27T14:47:14+00:00

This converts the GPIO charger to use exclusively GPIO
descriptors, moving the two remaining platforms passing
global GPIO numbers over to using a GPIO descriptor table.

power: supply: bq27xxx_battery: Add the BQ28z610 Battery monitor

2020-07-29T20:33:10+00:00

Add the Texas Instruments BQ28z610 battery monitor.
The register address map is laid out the same as compared to other
devices within the file.

The battery status register bits are similar to the bq27z561 but they
are different compared to other fuel gauge devices within this file.

The battery status register has differing bits to determine if the
battery is full, discharging or dead.
