Subject: [PATCH v3 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 mfd and regulator subsystems have been placed together in
this series. Here, both patches from both subsystems depend on the other:
1. The regulator driver patch includes a header file which describes the
   PMIC registers. This header is introduced in a PMIC patch.
2. The PMIC dt-binding patch references the regulator documentation.

Note that 1. is a build dependency, but 2. is not.

This patch series is a part of Exynos7870 upstreaming.

Changes in v3:
- Lowercase "ldo" and "buck" in regulator dt-bindings and driver patches.
- Add back missing Reviewed-by: tag in [PATCH v2 2/3].
- Link to v2: https://lore.kernel.org/r/20250219-exynos7870-pmic-regulators-v2-0-1ea86fb332f7@disroot.org

Changes in v2:
- Drop applied [PATCH 2/4].
- 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). Subsequently, drop Reviewed-by: tag in
  [PATCH 4/4].
- 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
