regulator: tps6594-regulator: Add TI TPS65224 PMIC regulators
Add support for TPS65224 regulators (bucks and LDOs) to TPS6594 driver as they have significant functional overlap. TPS65224 PMIC has 4 buck regulators and 3 LDOs. BUCK12 can operate in dual phase. The output voltages are configurable and are meant to supply power to the main processor and other components.

This driver supports TPS6594 voltage regulator chips.
|
||||
This driver supports TPS6594 series and TPS65224 voltage regulator chips.
|
||||
TPS6594 series of PMICs have 5 BUCKs and 4 LDOs
|
||||
voltage regulators.
|
||||
BUCKs 1,2,3,4 can be used in single phase or multiphase mode.
|
||||
Part number defines which single or multiphase mode is i used.
|
||||
It supports software based voltage control
|
||||
for different voltage domains.
|
||||
TPS65224 PMIC has 4 BUCKs and 3 LDOs. BUCK12 can be used in dual phase.
|
||||
All BUCKs and LDOs volatge can be controlled through software.
