Subject: [PATCH v1 2/2] regulator: tps65214: Add TI TPS65214 Regulator Support
Add support for TPS65214 regulators (bucks and LDOs) to the TPS65219
Regulator Driver as the TPS65214/TPS65214/TPS65219 PMIC devices have
significant register map overlap. TPS65214 is a Power Management IC with 3
Buck regulators (like TPS65215/TPS65219) and has 2 LDOs (like TPS65215).

- This driver supports TPS65219 series and TPS65215 voltage regulator chips.
+ This driver supports TPS65219, TPS65215, and TPS65214 voltage
+ regulator chips.
TPS65219 series of PMICs have 3 single phase BUCKs & 4 LDOs
voltage regulators.
TPS65215 PMIC has 3 single phase BUCKs & 2 LDOs.
- Both PMICs support software based voltage control for different voltage domains.
+ TPS65214 PMIC has 3 synchronous stepdown DC-DC converters & 2
+ LDOs. One LDO supports a maximum output current of 300 mA and the
+ other a maximum of 500 mA
+ All 3 PMICs support software based voltage control for different
+ voltage domains.
