+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.
+- reg-names : shall contain the register names of LPASS domain
+ "lpass_gcc", "lpass_cc", "lpass_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 {
+ compatible = "qcom,sdm845-lpasscc";
+ reg = <0x00147000 0x20>, <0x17014000 0x1f004>,
+ <0x17300020 0x20>;
+ reg-names = "lpass_gcc", "lpass_cc", "lpass_qdsp6ss";
+ #clock-cells = <1>;
+ };
