power: supply: da9150-fg: remove VLA usage

2018-03-12T13:34:52+00:00

In preparation to enabling -Wvla, remove VLA usage and replace it with fixed-length arrays. DA9150_QIF_LONG_SIZE (4 bytes) is the biggest size of an attribute which can be accessed [1]. Fixed as part of the directive to remove all VLAs from the kernel: https://lkml.org/lkml/2018/3/7/621 [1] https://marc.info/?l=kernel-hardening&m=152059600524753&w=2 Signed-off-by: Gustavo A. R.

power: supply: bq2415x: add DT referencing support

Add support for using bq2415x together with power_supply_am_i_supplied(). Signed-off-by: Sebastian Reichel

power: supply: bq27xxx: support missing supplier device

2018-03-12T13:30:09+00:00

power_supply_am_i_supplied() can return negative error codes. In this case we should assume, that no charger is connected and the battery should be marked as DISCHARGING instead of NOT_CHARGING. Reported-by: Merlijn Wajer Signed-off-by: Sebastian Reichel

max17042: propagate of_node to power supply device

2018-03-12T13:29:52+00:00

max17042_get_status uses the core power_supply_am_i_supplied. That function relies on DT properties to figure out the power supply topology, and will error out without DT. Fixes max17042 battery status being reported as "unknown". Signed-off-by: Pierre Bourdon Signed-off-by: Andre Heider Signed-off-by: Sebastian Reichel

power: supply: axp288_fuel_gauge: Fix full status reporting

2018-03-09T17:02:20+00:00

Commit 2b5a4b4bf222 ("power: supply: axp288_fuel_gauge: Rework get_status()"), switched from 0A current detection to using the capacity register for full detection. It turns out this fixes full reporting on some devices which keep trickle charging long after the capacity register reach 100%, but breaks it on some other devices where the charger stops charging before the capacity register reaches 100%. This commit fixes this by also checking for 0A current when the reported capacity is above 90%.

power: supply: axp288_fuel_gauge: Do not register FG on ECS EF20EA

2018-03-09T16:21:11+00:00

The ECS EF20EA laptop ships an AXP288 but it is actually using a different, separate FG chip for AC and battery monitoring. On this laptop we need to keep using the regular ACPI driver and disable the AXP288 FG to avoid reporting two batteries to userspace. Signed-off-by: Carlo Caione Signed-off-by: Sebastian Reichel

power: supply: axp20x_battery: add support for AXP813

2018-03-09T15:52:33+00:00

The X-Powers AXP813 PMIC has got some slight differences from AXP20X/AXP22X PMICs: - the maximum voltage supplied by the PMIC is 4.35 instead of 4.36/4.24 for AXP20X/AXP22X, - the constant charge current formula is different, It also has a bit to tell whether the battery percentage returned by the PMIC is valid.

power: supply: axp20x_battery: use data struct for variant specific code

2018-03-09T15:51:06+00:00

We used to use IDs to select a function or a feature depending on the variant. It's easier to maintain the code by adding data structure storing the few differences between variants so that we don't add a pile of if conditions. Let's use this data structure and update the code to use it.
