Support ROHM BD96801 "scalable" PMIC. The ROHM BD96801 is automotive grade PMIC, intended to be usable in multiple solutions. The BD96801 can be used as a stand-alone, or together with separate 'companion PMICs'. This modular approach aims to make this PMIC suitable for various use-cases. This series brings only limited support. The more complete set of features was sent in the RFC: https://lore.kernel.org/lkml/cover.1712058690.git.mazziesaccount@xxxxxxxxx/ As writing of this there is no known system using the ERRB interrupts, or doing configurations which require the PMIC to be in STBY state using Linux driver. Hence it felt natural to upstream only partial support for now, while leaving a note about the RFC series with more complete support for those who may need it later. Revision history still tries to summarize changes from the RFC for the reviewers. Revision history: RFCv2 => v1: - Drop ERRB IRQ from drivers (but not DT bindings). - Drop configuration which requires STBY - state. - Fix the register lock race by moving it from the regulator driver to the MFD driver. - Fix watchdog timeout handling RFCv1 => RFCv2: - Tidying code based on feedback form Krzysztof Kozlowski and Lee Jones. - Documented undocumented watchdog related DT properties. - Added usage of the watchdog IRQ. - Use irq_domain_update_bus_token() to work-around debugFS name collision for IRQ domains. --- Matti Vaittinen (6): dt-bindings: ROHM BD96801 PMIC regulators dt-bindings: mfd: bd96801 PMIC core mfd: support ROHM BD96801 PMIC core regulator: bd96801: ROHM BD96801 PMIC regulators watchdog: ROHM BD96801 PMIC WDG driver MAINTAINERS: Add ROHM BD96801 'scalable PMIC' entries .../bindings/mfd/rohm,bd96801-pmic.yaml | 172 ++++ .../regulator/rohm,bd96801-regulator.yaml | 62 ++ MAINTAINERS | 4 + drivers/mfd/Kconfig | 13 + drivers/mfd/Makefile | 1 + drivers/mfd/rohm-bd96801.c | 278 ++++++ drivers/regulator/Kconfig | 12 + drivers/regulator/Makefile | 2 + drivers/regulator/bd96801-regulator.c | 896 ++++++++++++++++++ drivers/watchdog/Kconfig | 13 + drivers/watchdog/Makefile | 1 + drivers/watchdog/bd96801_wdt.c | 400 ++++++++ include/linux/mfd/rohm-bd96801.h | 215 +++++ include/linux/mfd/rohm-generic.h | 1 + 14 files changed, 2070 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/rohm,bd96801-pmic.yaml create mode 100644 Documentation/devicetree/bindings/regulator/rohm,bd96801-regulator.yaml create mode 100644 drivers/mfd/rohm-bd96801.c create mode 100644 drivers/regulator/bd96801-regulator.c create mode 100644 drivers/watchdog/bd96801_wdt.c create mode 100644 include/linux/mfd/rohm-bd96801.h base-commit: 4cece764965020c22cff7665b18a012006359095 -- 2.44.0 -- Matti Vaittinen, Linux device drivers ROHM Semiconductors, Finland SWDC Kiviharjunlenkki 1E 90220 OULU FINLAND ~~~ "I don't think so," said Rene Descartes.
