 Configuration of common clocks, which affect multiple consumer devices can
 be similarly specified in the clock provider node.

+==Protected clocks==
+
+Some platforms or firmwares may not fully expose all the clocks to the OS, such
+as in situations where those clks are used by drivers running in ARM secure
+execution levels. Such a configuration can be specified in device tree with the
+protected-clocks property in the form of a clock specifier list. This property should
+only be specified in the node that is providing the clocks being protected:
