+Qualcomm Technologies, Inc. Shared Direct Access Memory (SDAM)
+
+The SDAM provides scratch register space for the PMIC clients.
+This memory can be used by software to store information or communicate
+to/from the PBUS.
+
+Below are the DT bindings for this module
+
+Supported properties:
+
+- compatible
+  Usage:	required
+  Value type:	<string>
+  Definition:	Should be "qcom,spmi-sdam"
+
+- reg
+  Usage:	required
+  Value type:	<prop-encoded-array>
+  Definition:	The base address and size of the sdam peripheral.
+
+- Data cells
+  Usage:	required
+  Value type:	Subnodes with bindings described in bindings/nvmem/nvmem.txt.
+  Definition:	Cells defining the shared memory usage and configuration.
+
+Example:
+
+	sdam_1: sdam@b000 {
+		compatible = "qcom,spmi-sdam";
+		reg = <0xb000 0x100>;
+
+		....
+		/* Data cells */
+		restart_reason: restart@50 {
+			reg = <0x50 0x1>;
+			bits = <7 2>;
+		};
+	};
+
+= Data consumers =
+Are device nodes which consume nvmem data cells.
+
+Example:
+
+	{
+		...
+		nvmem-cells = <&restart_reason>;
+		nvmem-cell-names = "pmic_restart_reason";
+	};
