Add Texas Instruments BQ25703A Charger

From: Chris Morgan <macromorgan@hotmail.com> Add support for the Texas Instruments BQ25703A charger manager. The device integrates a boost converter with the charger manager. This series adds the device as an MFD with separate regulator and power supply drivers. This allows us to manage a circular dependency with a type-c port manager which depends on the regulator for usb-otg but supplies power to the BQ25703A charger. --- Changes since RFC - Corrected some minor issues with code and device-tree labels. - Replaced most of the manufacturer specific device-tree properties with monitored-battery properties. Changes since V2 - Added reference to power-supply.yaml and removed note for i2c address per recommendation from Sebastian. - Corrected documentation error for charger driver found by kernel test robot. - Corrected duplicate POWER_SUPPLY_USB_TYPE_PD entry and corrected ichg logic in power supply changed function. - Corrected missing linux/bitfield.h header in regulator driver found by kernel test robot. --- Chris Morgan (5): dt-bindings: mfd: ti,bq25703a: Add TI BQ25703A Charger mfd: bq257xx: Add support for BQ25703A core driver power: supply: bq257xx: Add support for BQ257XX charger regulator: bq257xx: Add bq257xx boost regulator driver arm64: dts: rockchip: Add USB and charger to Gameforce Ace .../devicetree/bindings/mfd/ti,bq25703a.yaml | 121 +++ .../dts/rockchip/rk3588s-gameforce-ace.dts | 122 +++ drivers/mfd/Kconfig | 11 + drivers/mfd/Makefile | 1 + drivers/mfd/bq257xx.c | 104 +++ drivers/power/supply/Kconfig | 7 + drivers/power/supply/Makefile | 1 + drivers/power/supply/bq257xx_charger.c | 754 ++++++++++++++++++ drivers/regulator/Kconfig | 8 + drivers/regulator/Makefile | 1 + drivers/regulator/bq257xx-regulator.c | 189 +++++ include/linux/mfd/bq257xx.h | 108 +++ 12 files changed, 1427 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/ti,bq25703a.yaml create mode 100644 drivers/mfd/bq257xx.c create mode 100644 drivers/power/supply/bq257xx_charger.c create mode 100644 drivers/regulator/bq257xx-regulator.c create mode 100644 include/linux/mfd/bq257xx.h
