Subject: [PATCH v1 0/1] Add TI TPS65215 PMIC GPIO Support

TPS65214 is a Power Management Integrated Circuit (PMIC) that has
significant register map overlap with TPS65215 and TPS65219. The series 
introduces TPS65214 and adds the device to the multi-PMIC support driver.

This follow-up series is dependent on:
Commit 2c4fd76d13ec ("mfd: tps65214: Add support for TI TPS65214 PMIC")
Commit d23b7176df4a ("regulator: dt-bindings: Add TI TPS65214 PMIC bindings")

- TPS65214 is a Power Management IC with 3 Buck regulators and 2 LDOs.
- TPS65214 has 2 LDOS and 1 GPO, whereas TPS65219 has 4 LDOs and 2 GPOs.
- TPS65214's LDO1 maps to TPS65219's LDO3.
- A key difference between TPS65215 & TPS65214 are the LDO current and
  voltage output ranges and the configurable options available.
- The remaining features for both devices are the same.
