[PATCH v4 0/3] Add TI TPS65215 PMIC GPIO Support

From: Shree Ramamoorthy
Date: Fri Apr 25 2025 - 16:35:02 EST


Rebase patch series for 6.16 cycle. The related MFD series was integrated
in mainline during 6.15 cycle [0].

TPS65215 is a Power Management Integrated Circuit (PMIC) that has
significant register map overlap with TPS65219. The series introduces
TPS65215 and restructures the existing driver to support multiple devices.

- Both TPS65215 and TPS65219 have 3 Buck regulators.
- TPS65215 has 2 LDOs, whereas TPS65219 has 4 LDOs.
- TPS65215 and TPS65219's LDO1 are the same.
- TPS65215's LDO2 maps to TPS65219's LDO3.
- TPS65215 has 1 GPO, whereas TPS65219 has 2 GPOs.
- The remaining features are the same.
