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 is sent as an RFC because of the regulator features which can be configured only when the PMIC is in STBY state. This is described more detailed in the regulator patch. Another "oddity" is that the PMIC has two physical IRQ lines. When using regmap IRQ to create own IRQ controller instance for both HWIRQs, there will be a naming collison in debugfs for the IRQ domains. As a work-around the MFD driver uses irq_domain_update_bus_token(intb_domain, DOMAIN_BUS_WIRED); to append '-1' at the end of the domain name. Rest of the series ought to be business as usual. Revision history: 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 | 171 ++ .../regulator/rohm,bd96801-regulator.yaml | 69 + MAINTAINERS | 4 + drivers/mfd/Kconfig | 13 + drivers/mfd/Makefile | 1 + drivers/mfd/rohm-bd96801.c | 476 ++++ drivers/regulator/Kconfig | 12 + drivers/regulator/Makefile | 2 + drivers/regulator/bd96801-regulator.c | 2114 +++++++++++++++++ drivers/watchdog/Kconfig | 13 + drivers/watchdog/Makefile | 1 + drivers/watchdog/bd96801_wdt.c | 389 +++ include/linux/mfd/rohm-bd96801.h | 211 ++ include/linux/mfd/rohm-generic.h | 1 + 14 files changed, 3477 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 -- 2.43.2 -- Matti Vaittinen, Linux device drivers ROHM Semiconductors, Finland SWDC Kiviharjunlenkki 1E 90220 OULU FINLAND ~~~ "I don't think so," said Rene Descartes.
