+description: |
+  Loongson-2 SoC clock control module is an integrated clock controller, which
+  generates and supplies to all modules.

+  compatible:
+    enum:

+
+  '#clock-cells':
+    const: 1
+    description:
+      The clock consumer should specify the desired clock by having the clock
+      ID in its "clocks" phandle cell. See include/dt-bindings/clock/loongson,ls2k-clk.h
+      for the full list of Loongson-2 SoC clock IDs.
