+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>;
+ };
