Already merged regulator patches (in regulator tree - not yet in Linus' tree): [PATCH] regulator: ROHM bd7xxxx: Do not depend on parent driver data https://lore.kernel.org/lkml/20210105130221.GA3438042@localhost.localdomain/ [PATCH] regulator: bd718x7: Stop using parent data https://lore.kernel.org/lkml/20210107122355.GA35080@localhost.localdomain/ Already merged GPIO patch (in GPIO tree - not yet in Linus' tree): [PATCH] gpio: bd7xxxx: Do not depend on parent driver data https://lore.kernel.org/lkml/20210105125335.GA3430233@localhost.localdomain/ This series also includes already sent patches: The patches 1, 2 and 3 have been sent separately to mfd/regulator, rtc and clk subsystems - but they have not yet been reviewed / applied. They are present also in this series because the series depends on those changes. I will drop those patches from this series if they get merged to (MFD or regulator)/RTC/clk trees from previous submits. patch 1 previous submit: regulator: bd718x7, bd71828, Fix dvs voltage levels https://lore.kernel.org/lkml/20210118075851.GA1016281@localhost.localdomain/ patch 2 previous submit: rtc: bd70528: Do not require parent data https://lore.kernel.org/lkml/20210105152350.GA3714833@localhost.localdomain/ patch 3 previous submit: clk: BD718x7: Do not depend on parent driver data https://lore.kernel.org/lkml/20210105123028.GA3409663@localhost.localdomain/ Please note that due to the dependencies all of the patches are probably not applying cleanly to all subsystem trees. (regulator/RTC patches to other subsystems). I understand it perfectly well if this series can't be merged before all dependencies are merged to all relevant subsystem trees but I would be grateful if I got the first set of review comments even before that. ROHM BD71815 is a power management IC used in some battery powered systems. It contains regulators, GPO(s), charger + coulomb counter, RTC and a clock gate. All regulators can be controlled via I2C. LDO4 can additionally be set to be enabled/disabled by a GPIO. LDO3 voltage could be selected from two voltages written into separate VSEL reisters using GPIO but this mode is not supported by driver. On top of that the PMIC has the typical HW state machine which is present also on many other ROHM PMICs. IC contains two GPOs - but one of the GPOs is marked as GND in data-sheet. Thus the driver by default only exposes one GPO. The second GPO can be enabled by special DT property. RTC is almost similar to what is on BD71828. For currently used features only the register address offset to RTC block differs. The charger driver is not included in this series. ROHM has a charger driver with some fuel-gauging logig written in but this is not included here. I am working on separating the logic from HW specific driver and supporting both BD71815 and BD71828 chargers in separate patch series. Changelog v2: - Rebased on top of v5.11-rc3 - Added another "preliminary patch" which fixes HW-dvs voltage handling (patch 1) - split regulator patch to two. - changed dt-binding patch ordering. regulators: - staticized probe - removed some unnecessary defines - updated comments - split rohm-regulator patch adding SNVS and supporting simple linear mapping into two - one adding support for mapping, other adding SNVS. GPIO: - removed unnecessary headers - clarified dev/parent->dev usage - removed forgotten #define DEBUG dt-bindings: - changed patch order to meet ref-dependencies - added missing regulator nodes - changed string property for clk mode to tristated MFD: - header cleanups. CLK: - fixed commit message Matti Vaittinen (17): regulator: bd718x7, bd71828, Fix dvs voltage levels rtc: bd70528: Do not require parent data clk: BD718x7: Do not depend on parent driver data mfd: bd718x7: simplify by cleaning unnecessary device data dt_bindings: bd71828: Add clock output mode dt_bindings: regulator: Add ROHM BD71815 PMIC regulators dt_bindings: mfd: Add ROHM BD71815 PMIC mfd: Add ROHM BD71815 ID mfd: Support for ROHM BD71815 PMIC core gpio: support ROHM BD71815 GPOs regulator: helpers: Export helper voltage listing regulator: rohm-regulator: linear voltage support regulator: rohm-regulator: Support SNVS HW state. regulator: Support ROHM BD71815 regulators clk: bd718x7: Add support for clk gate on ROHM BD71815 PMIC rtc: bd70528: Support RTC on ROHM BD71815 MAINTAINERS: Add ROHM BD71815AGW .../bindings/mfd/rohm,bd71815-pmic.yaml | 202 ++++++ .../bindings/mfd/rohm,bd71828-pmic.yaml | 6 + .../regulator/rohm,bd71815-regulator.yaml | 116 +++ MAINTAINERS | 3 + drivers/clk/clk-bd718x7.c | 21 +- drivers/gpio/Kconfig | 10 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-bd71815.c | 171 +++++ drivers/mfd/Kconfig | 15 +- drivers/mfd/rohm-bd71828.c | 416 ++++++++++- drivers/mfd/rohm-bd718x7.c | 43 +- drivers/regulator/Kconfig | 11 + drivers/regulator/Makefile | 1 + drivers/regulator/bd71815-regulator.c | 682 ++++++++++++++++++ drivers/regulator/helpers.c | 36 +- drivers/regulator/rohm-regulator.c | 32 +- drivers/rtc/Kconfig | 6 +- drivers/rtc/rtc-bd70528.c | 104 ++- include/linux/mfd/rohm-bd71815.h | 561 ++++++++++++++ include/linux/mfd/rohm-bd71828.h | 3 + include/linux/mfd/rohm-bd718x7.h | 13 - include/linux/mfd/rohm-generic.h | 19 +- include/linux/regulator/driver.h | 2 + 23 files changed, 2321 insertions(+), 153 deletions(-) create mode 100644 Documentation/devicetree/bindings/mfd/rohm,bd71815-pmic.yaml create mode 100644 Documentation/devicetree/bindings/regulator/rohm,bd71815-regulator.yaml create mode 100644 drivers/gpio/gpio-bd71815.c create mode 100644 drivers/regulator/bd71815-regulator.c create mode 100644 include/linux/mfd/rohm-bd71815.h
