+description: |
+  This is a part of device tree bindings for S2M and S5M family of Power
+  Management IC (PMIC).
+
+  The S2MPS11/13/15 and S5M8767 provide three(AP/CP/BT) buffered 32.768 kHz
+  outputs. The S2MPS14 provides two (AP/BT) buffered 32.768 KHz outputs.
+
+  All available clocks are defined as preprocessor macros in
+  dt-bindings/clock/samsung,s2mps11.h header.
+
+  See also Documentation/devicetree/bindings/mfd/samsung,s2mps11.yaml for
+  additional information and example.
