Pull power supply and reset updates from Sebastian Reichel: "This time there are lots of changes. Quite a few changes to the core, lots of driver changes and one change to kobject core (with Ack from Greg). Summary: kobject: - Increase number of allowed uevent variables power-supply core: - Add power-supply type in uevent - Cleanup property handling in core - Make property and usb_type pointers const - Convert core power-supply DT binding to YAML - Cleanup HWMON code - Add new health status "calibration required" - Add new properties for manufacture date and capacity error margin battery drivers: - new cw2015 battery driver used by pine64 Pinebook Pro laptop - axp22: blacklist on Meegopad T02 - sc27xx: support current/voltage reading - max17042: support time-to-empty reading - simple-battery: add more battery parameters - bq27xxx: convert DT binding document to YAML - sbs-battery: add TI BQ20Z65 support, fix technology property, convert DT binding to YAML, add option to disable charger broadcasts, add new properties: manufacture date, capacity error margin, average current, charge current and voltage and support calibration required health status - misc fixes charger drivers: - bq25890: cleanup, implement charge type, precharge current and input current limiting properties - bd70528: use new linear range helper library - bd99954: new charger driver - mp2629: new charger driver - misc fixes reboot drivers: - oxnas-restart: introduce new driver - syscon-reboot: convert DT binding to YAML, add parent syscon device support - misc fixes" * tag 'for-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply: (85 commits) power: supply: cw2015: Attach OF ID table to the driver power: reset: gpio-poweroff: add missing '\n' in dev_err() Revert "power: supply: sbs-battery: simplify read_read_string_data" Revert "power: supply: sbs-battery: add PEC support" dt-bindings: power: sbs-battery: Convert to yaml power: supply: sbs-battery: constify power-supply property array power: supply: sbs-battery: switch to i2c's probe_new power: supply: sbs-battery: switch from of_property_* to device_property_* power: supply: sbs-battery: add ability to disable charger broadcasts power: supply: sbs-battery: fix idle battery status power: supply: sbs-battery: add POWER_SUPPLY_HEALTH_CALIBRATION_REQUIRED support power: supply: sbs-battery: add MANUFACTURE_DATE support power: supply: sbs-battery: add POWER_SUPPLY_PROP_CONSTANT_CHARGE_CURRENT/VOLTAGE_MAX support power: supply: sbs-battery: Improve POWER_SUPPLY_PROP_TECHNOLOGY support power: supply: sbs-battery: add POWER_SUPPLY_PROP_CURRENT_AVG support power: supply: sbs-battery: add PEC support power: supply: sbs-battery: simplify read_read_string_data power: supply: sbs-battery: add POWER_SUPPLY_PROP_CAPACITY_ERROR_MARGIN support power: supply: sbs-battery: Add TI BQ20Z65 support power: supply: core: add POWER_SUPPLY_HEALTH_CALIBRATION_REQUIRED ...
