The ROHM BD72720 is a new power management IC for portable, battery powered devices. It integrates 10 BUCKs and 11 LDOs, RTC, charger, LEDs, GPIOs and a clock gate. To me the BD72720 seems like a successor to the BD71828 and BD71815 PMICs. This series depends on the series: "[PATCH v5 0/3] power: supply: add charger for BD71828": https://lore.kernel.org/all/20250918-bd71828-charger-v5-0... sent by Andreas. The power-supplly and MAINTAINERs patches (2/3 and 3/3) from that serties aren't merged yet. Revision history: RFCv1 => v2: - Drop RFC status - Use stacked regmaps to hide secondary map from the sub-drivers - Quite a few styling fixes and improvements as suggested by reviewers. More accurate changelog in individual patches. - Link to v1: https://lore.kernel.org/all/cover.1759824376.git.mazziesa... --- Matti Vaittinen (15): dt-bindings: regulator: ROHM BD72720 dt-bindings: Add trickle-charge upper limit dt-bindings: power: supply: BD72720 managed battery dt-bindings: mfd: ROHM BD72720 dt-bindings: leds: bd72720: Add BD72720 mfd: rohm-bd71828: Use regmap_reg_range() mfd: bd71828: Support ROHM BD72720 regulator: bd71828: rename IC specific entities regulator: bd71828: Support ROHM BD72720 gpio: Support ROHM BD72720 gpios clk: clk-bd718x7: Support BD72720 clk gate rtc: bd70528: Support BD72720 rtc power: supply: bd71828: Support wider register addresses power: supply: bd71828-power: Support ROHM BD72720 MAINTAINERS: Add ROHM BD72720 PMIC .../bindings/leds/rohm,bd71828-leds.yaml | 7 +- .../bindings/mfd/rohm,bd72720-pmic.yaml | 269 +++++ .../bindings/power/supply/battery.yaml | 3 + .../power/supply/rohm,vdr-battery.yaml | 80 ++ .../regulator/rohm,bd72720-regulator.yaml | 153 +++ MAINTAINERS | 2 + drivers/clk/Kconfig | 4 +- drivers/clk/clk-bd718x7.c | 10 +- drivers/gpio/Kconfig | 9 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-bd72720.c | 281 +++++ drivers/mfd/Kconfig | 18 +- drivers/mfd/rohm-bd71828.c | 546 ++++++++- drivers/power/supply/bd71828-power.c | 160 ++- drivers/regulator/Kconfig | 8 +- drivers/regulator/bd71828-regulator.c | 1025 ++++++++++++++++- drivers/rtc/Kconfig | 3 +- drivers/rtc/rtc-bd70528.c | 21 +- include/linux/mfd/rohm-bd72720.h | 634 ++++++++++ include/linux/mfd/rohm-generic.h | 1 + 20 files changed, 3106 insertions(+), 129 deletions(-) create mode 100644 Documentation/devicetree/bindings/mfd/rohm,bd72720-pmic.yaml create mode 100644 Documentation/devicetree/bindings/power/supply/rohm,vdr-battery.yaml create mode 100644 Documentation/devicetree/bindings/regulator/rohm,bd72720-regulator.yaml create mode 100644 drivers/gpio/gpio-bd72720.c create mode 100644 include/linux/mfd/rohm-bd72720.h -- 2.51.0
