+======
+AS3722 supports one 32KHz clock to output from device. The clock control is
+provided through the clock driver.
+This binding uses the common clock binding ./clock-bindings.txt.
+The device node should have the optional properties to support the clock:
+#clock-cells: from common clock binding; shall be set to 1. The clock id for
+	single clock output is 0.

 Example:
 --------
 #include <dt-bindings/mfd/as3722.h>
