From: ChiaEn Wu <chiaen_wu@xxxxxxxxxxx> This patch set is to add Richtek RT9467 5A Battery Charger support. RT9467 is a switch-mode single cell Li-Ion/Li-Polymer battery charger for portable applications. It integrates a synchronous PWM controller, power MOSFETs, input current sensing and regulation, high-accuracy voltage regulation, and charge termination. The charge current is regulated through integrated sensing resistors. The RT9467 also features USB On-The-Go (OTG) support. It also integrates D+/D- pin for USB host/charging port detection. This charger driver is based on a 'linear_ranger' queued patch which adds 'LINEAR_RANGE_IDX' macro for declaring the linear_range struct simply. https://lore.kernel.org/all/20220920161218.dkkfvfomrruebahi@xxxxxxxxxxxxxxxxxxxxxx/ Thank you, ChiaEn Wu --- Change in v2: - In Patch 1/3 (dt-bindings: RT9467 Charger DTS) - Revise the definition of 'enable-gpios' - Revise the node name to generic name in the example ('rt9467@5b' --> 'charger@5b') - Revise the example usage of 'charge-enable-gpios' with GPIO flags - In Patch 2/3 (power: supply: RT9467 Charger Driver) - Add missing header file <linux/bitfied.h> - Add new header files <linux/sysfs.h> and <linux/kstrtox.h> for adding 'sysoff' sysfs feature - Add assign 'rt9467_sysfs_groups' to '.attr_grp' of psy config - Remove unused varible 'rt9467_port_stat_names[]' - In Patch 3/3 (ABI Documentation for RT9467 sysfs attribute) - New file since v2 patchset ChiaEn Wu (3): dt-bindings: power: supply: Add Richtek RT9467 battery charger power: supply: rt9467: Add Richtek RT9467 charger driver Documentation: power: rt9467: Document exported sysfs entries Documentation/ABI/testing/sysfs-class-power-rt9467 | 19 + .../power/supply/richtek,rt9467-charger.yaml | 82 ++ drivers/power/supply/Kconfig | 19 + drivers/power/supply/Makefile | 1 + drivers/power/supply/rt9467-charger.c | 1282 ++++++++++++++++++++ 5 files changed, 1403 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-class-power-rt9467 create mode 100644 Documentation/devicetree/bindings/power/supply/richtek,rt9467-charger.yaml create mode 100644 drivers/power/supply/rt9467-charger.c -- 2.7.4
