Initial support for ROHM BD9576MUF and BD9573MUF PMICs. These PMICs are primarily intended to be used to power the R-Car family processors. BD9576MUF includes some additional safety features the BD9573MUF does not have. This initial version of drivers does not utilize these features and for now the SW behaviour is identical. This patch series includes MFD and watchdog drivers. Regulator part was already applied. - Enabling and pinging the watchdog - configuring watchog timeout / window from device-tree This patch series does not bring interrupt support. BD9576MUF and BD9573MUF are designed to keep the IRQ line low for whole duration of error condition. IRQ can't be 'acked'. So proper IRQ support would require some IRQ limiter implementation (delayed unmask?) in order to not hog the CPU. Changelog v5: - rebased on top of v5.10-rc2 - few styling fixes in MFD as suggested by Lee Changelog v4: - rebased on top of 5.10-rc1 - Fix typo (repeated word maximum) from the DT binding doc Changelog v3: - use only one binding to specify watchdog time-out window. Changelog v2: - dropped already applied regulator part - dt_bindings: Fix case for regulator-names in the example - watchdod: unify probe error check and revise includes --- Matti Vaittinen (4): dt_bindings: mfd: Add ROHM BD9576MUF and BD9573MUF PMICs mfd: Support ROHM BD9576MUF and BD9573MUF wdt: Support wdt on ROHM BD9576MUF and BD9573MUF MAINTAINERS: Add ROHM BD9576MUF and BD9573MUF drivers .../bindings/mfd/rohm,bd9576-pmic.yaml | 123 ++++++++ MAINTAINERS | 4 + drivers/mfd/Kconfig | 11 + drivers/mfd/Makefile | 1 + drivers/mfd/rohm-bd9576.c | 108 +++++++ drivers/watchdog/Kconfig | 13 + drivers/watchdog/Makefile | 1 + drivers/watchdog/bd9576_wdt.c | 290 ++++++++++++++++++ include/linux/mfd/rohm-bd957x.h | 59 ++++ include/linux/mfd/rohm-generic.h | 2 + 10 files changed, 612 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/rohm,bd9576-pmic.yaml create mode 100644 drivers/mfd/rohm-bd9576.c create mode 100644 drivers/watchdog/bd9576_wdt.c create mode 100644 include/linux/mfd/rohm-bd957x.h base-commit: 3cea11cd5e3b00d91caf0b4730194039b45c5891 -- 2.21.3 -- Matti Vaittinen, Linux device drivers ROHM Semiconductors, Finland SWDC Kiviharjunlenkki 1E 90220 OULU FINLAND ~~~ "I don't think so," said Rene Descartes.
