regulator: da9063: Add Dialog DA9063 voltage regulators support.
The driver adds support for the following DA9063 PMIC regulators:
- 11x LDOs (named LDO1 - LDO11),
- 6x buck converters (BCORE1, BCORE2, BPRO, BMEM, BIO, BPERI),
Regulators provide following operations:
- REGULATOR_CHANGE_STATUS and REGULATOR_CHANGE_VOLTAGE for all regulators,
- 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.
