+Qualcomm WCSS Clock Controller Binding
+-----------------------------------------------
+
+Required properties :
+- compatible : shall contain "qcom,qcs404-wcsscc"
+- #clock-cells : from common clock binding, shall contain 1.
+- reg : shall contain base register address and size,
+ in the order
+ Index-0 maps to WCSS_Q6SSTOP clocks register region
+ Index-1 maps to WCSS_TCSR register region
+ Index-2 maps to WCSS_QDSP6SS register region
+
+Optional properties :
+- reg-names : register names of WCSS domain
+ "wcss_q6sstop", "wcnss_tcsr", "wcss_qdsp6ss".
+
+Example:
+The below node has to be defined in the cases where the WCSS peripheral loader
+would bring the subsystem out of reset.
+
+ clock_wcsscc: qcom,wcsscc@7000000 {
+ compatible = "qcom,qcs404-wcsscc";
+ reg = <0x07500000 0x4e000>, <0x07550000 0x8012>, <0x07400000 0x104>;
+ reg-names = "wcss_q6sstop", "wcnss_tcsr", "wcss_qdsp6ss";
+ #clock-cells = <1>;
+ };
