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

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.

Change Log:
v3 -> v4:
- Update cover letter
- Rebase for 6.16 cycle
v2 -> v3:
- Correct gpio_chip.ngpio line to use .offset field
- Remove unnecessary newlines
v1 -> v2:
- have any PMIC lists be in alpha-numeric order: TPS65215, then TPS65219
- remove comma after terminator
- Add driver prefix to chip_data struct
