[PATCH v1 0/2] Add TI TPS65214 PMIC Regulator Support

[Shree Ramamoorthy]

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")

- 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.

[PATCH v1 2/2] regulator: tps65214: Add TI TPS65214 Regulator Support

[Shree Ramamoorthy]

Add support for TPS65214 regulators (bucks and LDOs) to the TPS65219
Regulator Driver as the TPS65214/TPS65214/TPS65219 PMIC devices have
significant register map overlap. TPS65214 is a Power Management IC with 3
Buck regulators (like TPS65215/TPS65219) and has 2 LDOs (like TPS65215).

Hm? How so? Where is this commit?

This:

tells me that it is depending on this patchset.

Are these all dependencies or just reference?

I combined this TPS65214 series with TPS65215: https://lore.kernel.org/all/20250131221139.342967-1-s-ramamoorthy@ti.com/
I will be re-sending the v5 with Krzysztof's feedback added soon. That would be the replacement patch series to try applying.
Thank you for your time!
