Subject: [PATCH v2 0/7] Add TI TPS65215 PMIC Regulator Support

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.

This follow-up series is dependent on the TPS65215 MFD Driver Series:
Commit c3cc37e8d23d ("mfd: tps65215: Add support for TI TPS65215 PMIC")
Commit 5f0f36835b90 ("mfd: tps65215: Remove regmap_read check")

TPS65219 Cleanup Series:
GPIO: https://lore.kernel.org/all/20241217204755.1011731-1-s-ramamoorthy@ti.com/
MFD: https://lore.kernel.org/all/20241217204935.1012106-1-s-ramamoorthy@ti.com/
Reg: https://lore.kernel.org/all/20241217204526.1010989-1-s-ramamoorthy@ti.com/

- 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:
v1 -> v2:
- have any PMIC lists be in alpha-numeric order: TPS65215, then TPS65219
- Add driver prefix to chip_data struct
- Have probe() helper functions use dev_err_probe instead of dev_err() to 
  log the error code in a human readable format & combined with return, it 
  saves a few LoC since { } can be removed.
- Add error handling of 'irq_data' in probe() as previously done.
