+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
+
+examples:
+ - |
+ #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";
+ };
