Merge tag 'for-v5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply
Pull power supply and reset updates from Sebastian Reichel: "Core: - Add over-current health state - Add standard, adaptive and custom charge types - Add new properties for start/end charge threshold New Drivers / Hardware: - UCS1002 Programmable USB Port Power Controller - Ingenic JZ47xx Battery Fuel Gauge - AXP20x USB Power: Add AXP813 support - AT91 poweroff: Add SAM9X60 support - OLPC battery: Add XO-1.5 and XO-1.75 support Misc Changes: - syscon-reboot: support mask property - AXP288 fuel gauge: Blacklist ACEPC T8/T11. Looks like some vendor thought it's a good idea to build a desktop system with a fuel gauge, that slowly "discharges"... - cpcap-battery: Fix calculation errors - misc fixes" * tag 'for-v5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply: (54 commits) power: supply: olpc_battery: force the le/be casts power: supply: ucs1002: Fix build error without CONFIG_REGULATOR power: supply: ucs1002: Fix wrong return value checking power: supply: Add driver for Microchip UCS1002 dt-bindings: power: supply: Add bindings for Microchip UCS1002 power: supply: core: Add POWER_SUPPLY_HEALTH_OVERCURRENT constant power: supply: core: fix clang -Wunsequenced power: supply: core: Add missing documentation for CHARGE_CONTROL_* properties power: supply: core: Add CHARGE_CONTROL_{START_THRESHOLD,END_THRESHOLD} properties power: supply: core: Add Standard, Adaptive, and Custom charge types power: supply: axp288_fuel_gauge: Add ACEPC T8 and T11 mini PCs to the blacklist power: supply: bq27xxx_battery: Notify also about status changes power: supply: olpc_battery: Have the framework register sysfs files for us power: supply: olpc_battery: Add OLPC XO 1.75 support power: supply: olpc_battery: Avoid using platform_info power: supply: olpc_battery: Use devm_power_supply_register() power: supply: olpc_battery: Move priv data to a struct power: supply: olpc_battery: Use DT to get battery version x86/platform/olpc: Use a correct version when making up a battery node x86/platform/olpc: Trivial code move in DT fixup ...
