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 5bff79dad20a ("power: supply: Add bd718(15/28/78) charger driver") which is in power-supply tree, for-next. Thus, the series is based on it. The testing of v4 suffered some hardware-issues after I accidentally enabled charging while the PMIC's battery pin was connected to the I/O domain. Some heat was generated, not terribly lot smoke though... After the incident I've had occasional I2C failures. I, however, suspect the root cause is HW damage in I/O lines since changes in this revision have been made to dt-bindings. It's still fair to note that though, as my testing was impacted. Revision history: v3 =3D> v4: - dt-binding fixes to the BD72720 MFD example and regulator bindings More accurate changelog in individual patches v2 =3D> v3: - rebased to power-supply/for-next as dependencies are merged to there - plenty of dt-binding changes as suggested by reviewers - add new patch to better document existing 'trickle-charging' property More accurate changelog in individual patches RFCv1 =3D> 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.mazziesaccount@gmail.c= om/ --- Matti Vaittinen (16): dt-bindings: regulator: ROHM BD72720 dt-bindings: battery: Clarify trickle-charge dt-bindings: battery: 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 | 338 ++++++ .../bindings/power/supply/battery.yaml | 11 +- .../power/supply/rohm,vdr-battery.yaml | 80 ++ .../regulator/rohm,bd72720-regulator.yaml | 148 +++ 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, 3177 insertions(+), 130 deletions(-) create mode 100644 Documentation/devicetree/bindings/mfd/rohm,bd72720-pmic= =2Eyaml create mode 100644 Documentation/devicetree/bindings/power/supply/rohm,vdr= -battery.yaml create mode 100644 Documentation/devicetree/bindings/regulator/rohm,bd7272= 0-regulator.yaml create mode 100644 drivers/gpio/gpio-bd72720.c create mode 100644 include/linux/mfd/rohm-bd72720.h base-commit: 8e8856396b54bea5c00a7ae88d87c6254aef2d94 --=20 2.51.1 --dKFZS09m7tQZCgSp Content-Type: application/pgp-signature; name=signature.asc -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEEIx+f8wZb28fLKEhTeFA3/03aocUFAmkVm/kACgkQeFA3/03a ocX7IwgAzz6P/Y+KNbJ7ZjWahFcHUI1wgYDFcf/SlBI/HhU9hi+MX66swIV7RDkm VU8AUpREZDAa8F+YPBoDb+SWRVVkwN9NzP4rLsWiBL66HaHFtabSm0vRglj6AEY3 71wtOXR0faeX2crZd8J2ID861dHix3A2mxomBmoAL6kF1E8arv7rIhyx3RonJ1dH rIT/DaJ7f/O7zJOHm9/YKTk4sN6paGFqGOIsj4qvLq87E/+70MZ02RsfSLWUDEIM 4ITyfhALAxsa9Rq0Qw5XFB5jQzpQw7SCrJ+ms8Dkx2TX9H94UXj7Tj7pW6jTOa+L 6GPekxZMEliDsXSVFdBkg/d3zK6C9Q== =03Sq -----END PGP SIGNATURE----- --dKFZS09m7tQZCgSp--
