2018-03-09power: supply: axp288_fuel_gauge: Fix full status reportingHans de Goede1-12/+35
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%.

2018-03-09power: supply: axp288_fuel_gauge: Do not register FG on ECS EF20EACarlo Caione1-0/+6
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.

2018-03-09power: reset: gpio-poweroff: Support for timeout from device propertyMoritz Fischer1-2/+6
Add support for reading a timeout value from device property. Fall back to previous default of 3s if nothing is specified. Signed-off-by: Moritz Fischer <mdf@kernel.org> Signed-off-by: Sebastian Reichel <sre@kernel.org>

2018-03-09power: reset: Add Spreadtrum SC27xx PMIC power off supportBaolin Wang3-0/+76
On Spreadtrum platform, we need power off system through external SC27xx series PMICs including the SC2720, SC2721, SC2723, SC2730 and SC2731 chips. Thus this patch adds SC27xx series PMICs power-off support. Signed-off-by: Baolin Wang <baolin.wang@linaro.org> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>
2018-03-09power: supply: axp20x_battery: add support for AXP813Quentin Schulz1-0/+42
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.

2018-03-09power: supply: axp20x_battery: use data struct for variant specific codeQuentin Schulz1-35/+67
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.

The Microsemi Ocelot SoC has a register allowing to reset the MIPS core. Unfortunately, the syscon-reboot driver can't be used directly (but almost) as the reset control may be disabled using another register.
