+description: |
+  The MT7621 can gate SoC device clocks.
+
+  Each clock gate is assigned an identifier and client nodes use this identifier
+  to specify the clock gate which they consume.
+
+  All these identifiers could be found in:
+  [1]: <include/dt-bindings/clock/mt7621-clk.h>.
+
+properties:
+  compatible:
+    const: mediatek,mt7621-clk
+
+  "#clock-cells":
+    description:
+      The first cell indicates the clock gate number, see [1] for available
+      clocks.
+    const: 1
+
+  ralink,sysctl:
+    $ref: /schemas/types.yaml#/definitions/phandle
+    description:
+      phandle to the syscon which is in the same address area with syscon
+      device.
+
+required:
+  - compatible
+  - '#clock-cells'
+  - ralink,sysctl

+examples:

+    #include <dt-bindings/clock/mt7621-clk.h>
