The RT9759 is a high efficiency and high charge current charger. The efficiency is up to 97.8% when VBAT=4.2V, IBAT=2.5A, and the maximum charge current is up to 8A. The device integrates smart cap divider topology with a dual-phase charge pump core and 9 channel high speed ADCs to monitor the charging process. Since v4: - Since it's 2023 now, change date from 2022 to 2023 for source code and ABI. Since v3: - Fix 0002 patch title typo (from 'rt9471' to 'rt9759') - Remove unused R_VAC_OVP range. - Refer to ABI document, use 'status' to control battery charging, not 'online' - Refer to ABI document, use 'online' to indicate bus state Since v2: - Add Reviewed-by tag for dt-binding patch - Change ABI document date from Oct 2022 to Nov 2022 and KernelVersion from 6.1 to 6.2 ChiYuan Huang (3): dt-bindings: power: supply: Add Richtek RT9759 smart cap divider charger power: supply: Add Richtek RT9759 smart cap divider charger Documentation: power: rt9759: Document exported sysfs entries Documentation/ABI/testing/sysfs-class-power-rt9759 | 37 ++ .../bindings/power/supply/richtek,rt9759.yaml | 61 ++ drivers/power/supply/Kconfig | 15 + drivers/power/supply/Makefile | 1 + drivers/power/supply/rt9759.c | 613 +++++++++++++++++++++ 5 files changed, 727 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-class-power-rt9759 create mode 100644 Documentation/devicetree/bindings/power/supply/richtek,rt9759.yaml create mode 100644 drivers/power/supply/rt9759.c
