Subject: [PATCH v2 0/3] Introduce support for Exynos7870's S2MPU05 PMIC and
 its regulators

Exynos7870 devices use Samsung S2MPU05 as its primary PMIC. Add support
for it in the existing PMIC driver. Additionally, also add support for
voltage regulators which can be accessed and controlled from the PMIC
itself.

Patches from two subsystems have been placed in a single series here as
header files and documentation YAML references have been shared.

This patch series is a part of Exynos7870 upstreaming.

- Added myself as maintainer in s2mpu05-pmic DT docs.
- Edited LDO description to explain missing LDOs.
- Added all missing regulator control registers intended for CP.
- Modify regulator_desc_s2mpu05_ldo* macros to allow choosing register
  suffixes (CTRL, CTRL1, etc).
- Take over ownership of patches by the co-author, upon their request.
- Link to v1: https://lore.kernel.org/r/20250204-exynos7870-pmic-regulators-v1-0-05adad38102c@disroot.org
