This is MFD module providing access to registers and interrupts of DA906x
series PMIC. It is used by other functional modules, registered as MFD cells.
Driver uses regmap with paging to access extended register list. Register map
is divided into two pages, where the second page is used during initialisation.
This module provides support to following functional cells:
- Regulators
- RTC
- HWMON
- OnKey (power key misc input device)
- Vibration (force-feedback input device)
- Watchdog
- LEDs

The driver adds support for the following DA9063 PMIC regulators:
- 11x LDOs (named LDO1 - LDO11),
- 6x buck converters (BCORE1, BCORE2, BPRO, BMEM, BIO, BPERI),
- 1x power switch to switch on/off 32 KHz oscilator output (32K_OUT).
Regulators provide following operations:
- REGULATOR_CHANGE_STATUS for all regulators,
- REGULATOR_CHANGE_VOLTAGE for LDOs and buck converters,
- REGULATOR_CHANGE_MODE for LDOs and buck converters, where:
- LDOs allow REGULATOR_MODE_NORMAL and REGULATOR_MODE_STANDBY,
- buck converters allow REGULATOR_MODE_FAST, REGULATOR_MODE_NORMAL
and REGULATOR_MODE_STANDBY,
- REGULATOR_CHANGE_CURRENT for buck converters (current limits).
The driver generates REGULATOR_EVENT_OVER_CURRENT for LDO3, LDO4, LDO7, LDO8
and LDO11.
Internally, PMIC provides two voltage configurations for normal and suspend
system state for each regulator. The driver switches between those on
suspend/wake-up to provide quick and fluent output voltage change.
This driver requires MFD core driver for operation.
