+Qualcomm AOSS Reset Controller
+======================================
+
+This binding describes a reset-controller found on AOSS (Always on SubSysem)
+for Qualcomm SDM845 SoCs.
+
+Required properties:
+- compatible:
+	Usage: required
+	Value type: <string>
+	Definition: must be:
+		    "qcom,aoss-reset-sdm845", "syscon"
+
+- reg:
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: must specify the base address and size of the
+		    syscon device.
+
+
+- #reset-cells:
+	Usage: required
+	Value type: <uint>
+	Definition: must be 1; cell entry represents the reset index.
+
+example:
+
+aoss_reset: qcom,reset-controller@b2e0100 {
+	compatible = "qcom,aoss-reset-sdm845", "syscon";
+	reg = <0xc2b0000 0x20004>;
+	#reset-cells = <1>;
+};
+
+
+Specifying reset lines connected to IP modules
+==============================================
+
+Device nodes that need access to reset lines should
+specify them as a reset phandle in their corresponding node as
+specified in reset.txt.
+
+Example:
+
+	modem-pil@4080000 {
+		...
+
+		resets = <&aoss_reset AOSS_CC_MSS_RESTART>;
+		reset-names = "mss_restart";
+
+		...
+        };
+
+For list of all valid reset indicies see
+<dt-bindings/reset/qcom,aoss-sdm845.h>
