Subject: [PATCH v3 0/4] 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 8206c20f4c82 ("mfd: tps65215: Add support for TI TPS65215 PMIC")
Commit 0e0b7f00c111 ("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:
v2 -> v3:
dt-bindings: 
- Alphanumeric order for PMIC list
- add allOf:if:then: which will disallow :false two LDOs and their supplies

regulator.c:
- Revert addition of 2 probe helper functions
- Add empty tps65215_regulator_irq_types struct to minimize loops in probe
- Consolidate patches to define and use func/structs in the same patches to
  prevent build error due to no users of the defined functions
- Apply reverse xmas tree style to variable defintions in functions
- Remove unnecessary new lines & add new line after declarations

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.
