that lock sits above another mutex in the locking hierarchy.  That does

Configuration of common clocks, which affect multiple consumer devices can

==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:
