+
+description: |
+  Microchip PolarFire clock control is an integrated clock controller, which
+  generates clocks and supplies to all peripherals.
+
+properties:
+  compatible:
+    const: microchip,pfsoc-clkcfg
+
+  reg:
+    maxItems: 1
+
+  clocks:
+    items:
+      - description: reference clock input
+
+  clock-names:
+    items:
+      - const: ref_clk
+
+  '#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/microchip,pfsoc-clock.h
+      for the full list of PolarFire clock IDs.
