Subject: [PATCH v2 1/3] regulator: dt-bindings: add documentation for
 s2mpu05-pmic regulators

S2MPU05 is a PMIC found in Exynos7870 devices, which controls voltage
regulators (21 LDOs and 5 BUCKs). Provide documentation for devicetree
definitions, regulator naming patterns, etc.

+  This is a part of device tree bindings for S2M and S5M family of Power
+  Management IC (PMIC).
+
+  The S2MPU05 provides buck and LDO regulators.
+
+  See also Documentation/devicetree/bindings/mfd/samsung,s2mps11.yaml for
+  additional information and example.

+      LDOs 11-24 are used for CP, and they're left unimplemented due to lack
