-Qualcomm AOSS Reset Controller
-======================================
-
-This binding describes a reset-controller found on AOSS-CC (always on subsystem)
-for Qualcomm SDM845 SoCs.
-
-Required properties:
-- compatible:
-	Usage: required
-	Value type: <string>
-	Definition: must be:
-		    "qcom,sdm845-aoss-cc"
-
-- reg:
-	Usage: required
-	Value type: <prop-encoded-array>
-	Definition: must specify the base address and size of the register
-	            space.
-
-- #reset-cells:
-	Usage: required
-	Value type: <uint>
-	Definition: must be 1; cell entry represents the reset index.
-
-Example:
-
-aoss_reset: reset-controller@...0000 {
-	compatible = "qcom,sdm845-aoss-cc";
-	reg = <0xc2a0000 0x31000>;
-	#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.
-
-For list of all valid reset indicies see
-<dt-bindings/reset/qcom,sdm845-aoss.h>
-
-Example:
-
-modem-pil@...0000 {
-	...
-
-	resets = <&aoss_reset AOSS_CC_MSS_RESTART>;
-	reset-names = "mss_restart";
-
-	...
-};
