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 v3: - GPIO clean-up as suggested by Bartosz - MFD clean-up as suggested by Lee - clk-mode dt-binding handling in MFD driver corrected to reflect new property values. - Dropped already applied patches - Rebased on v5.12-rc2 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.
