+description: |
+  The MT7621 has a PLL controller from where the cpu clock is provided
+  as well as derived clocks for the bus and the peripherals. It also
+  can gate SoC device clocks.
+
+  Each clock is assigned an identifier and client nodes use this identifier
+  to specify the clock 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 number, see [1] for available
+      clocks.
+    const: 1
+
+  clock-output-names:
+    maxItems: 8

+required:
+  - compatible
+  - '#clock-cells'

+additionalProperties: false

+    #include <dt-bindings/clock/mt7621-clk.h>
+
+    pll {
+      compatible = "mediatek,mt7621-clk";
+      #clock-cells = <1>;
+      clock-output-names = "xtal", "cpu", "bus",
+                           "50m", "125m", "150m",
+                           "250m", "270m";
