-Qualcomm LPASS Clock Controller Binding
------------------------------------------------
-
-Required properties :
-- compatible		: shall contain "qcom,sdm845-lpasscc"
-- #clock-cells		: from common clock binding, shall contain 1.
-- reg			: shall contain base register address and size,
-			  in the order
-			Index-0 maps to LPASS_CC register region
-			Index-1 maps to LPASS_QDSP6SS register region
-
-Optional properties :
-- reg-names	: register names of LPASS domain
-		 "cc", "qdsp6ss".
-
-Example:
-
-The below node has to be defined in the cases where the LPASS peripheral loader
-would bring the subsystem out of reset.
-
-	lpasscc: clock-controller@17014000 {
-		compatible = "qcom,sdm845-lpasscc";
-		reg = <0x17014000 0x1f004>, <0x17300000 0x200>;
-		reg-names = "cc", "qdsp6ss";
-		#clock-cells = <1>;
-	};
