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/ The v3: implemented also support for ERRB interrupt and setting a name suffix to IRQ domains. That work was postponed and will be continued after some unrelated changes to irqdomain code are completed as discussed here: https://lore.kernel.org/all/87plst28yk.ffs@tglx/ Revision history still tries to summarize changes from the RFC for the reviewers. Revision history: v3 => v4: - Drop patches 7 to 10 (inclusive) until preparatory irqdomain changes are done. - Cleanups as suggested by Lee. - Change the regulator subdevice name. (MFD and regulators). - Minor styling in MFD driver v2 => v3: Mostly based on feedback from Thomas Gleixner - Added acks from Krzysztof and Mark - Rebased on v6.10-rc2 - Drop name suffix support for legacy IRQ domains (both irqdomain and regmap) - Improve the commit message for patch 7/10 v1 => v2: - Add support for setting a name suffix for fwnode backed IRQ domains. - Add support for setting a domain name suffix for regmap-IRQ. - Add handling of ERRB IRQs. - Small fixes based on feedback. 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. 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 | 173 ++++ .../regulator/rohm,bd96801-regulator.yaml | 63 ++ MAINTAINERS | 4 + drivers/mfd/Kconfig | 13 + drivers/mfd/Makefile | 1 + drivers/mfd/rohm-bd96801.c | 273 ++++++ drivers/regulator/Kconfig | 12 + drivers/regulator/Makefile | 2 + drivers/regulator/bd96801-regulator.c | 908 ++++++++++++++++++ drivers/watchdog/Kconfig | 13 + drivers/watchdog/Makefile | 1 + drivers/watchdog/bd96801_wdt.c | 416 ++++++++ include/linux/mfd/rohm-bd96801.h | 215 +++++ include/linux/mfd/rohm-generic.h | 1 + 14 files changed, 2095 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: 1613e604df0cd359cf2a7fbd9be7a0bcfacfabd0 -- 2.45.1 -- Matti Vaittinen, Linux device drivers ROHM Semiconductors, Finland SWDC Kiviharjunlenkki 1E 90220 OULU FINLAND ~~~ "I don't think so," said Rene Descartes.
