power: ab8500: remove unused header

2021-06-03T16:40:15Z

The ab8500.h header in linux/power is not referenced/included, so can be safely removed. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Sebastian Reichel

power: supply: bq27xxx: Add support for BQ78Z100

2021-03-21T20:29:26Z

Add support for TI BQ78Z100, I2C interface gas gauge. It provides a fully integrated safety protection and authentication for 1 to 2-series cell Li-Ion and Li-Polymer battery packs. The patch was tested with BQ78Z100 equipment.

power: supply: bq27xxx: fix power_avg for newer ICs

2021-03-15T01:26:03Z

On all newer bq27xxx ICs, the AveragePower register contains a signed value; in addition to handling the raw value as unsigned, the driver code also didn't convert it to µW as expected. At least for the BQ28Z610, the reference manual incorrectly states that the value is in units of 1mW and not 10mW. I have no way of knowing whether the manuals of other supported ICs contain the same error, or if there are models that actually use 1mW. At least, the new code shouldn't be *less* correct than the old version for any device. power_avg is removed from the cache structure, se we don't have to extend it to store both a signed value and an error code. Always getting an up-to-date value may be desirable anyways, as it avoids inconsistent current and power readings when switching between charging and discharging.

power: supply: max8903: Absorb pdata header

2021-01-12T22:23:49Z

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. Cc: Chris Lapa Cc: MyungJoo Ham Signed-off-by: Linus Walleij Signed-off-by: Sebastian Reichel

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

2020-11-30T01:42:42Z

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

2020-10-01T22:01:42Z

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

2020-08-28T17:27:45Z

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") Signed-off-by: Jonathan Bakker Signed-off-by: Sebastian Reichel

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

2020-08-28T17:27:45Z

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

2020-08-28T17:03:24Z

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. Signed-off-by: Jonghwa Lee Signed-off-by: Krzysztof Kozlowski Signed-off-by: Jonathan Bakker Signed-off-by: Sebastian Reichel
