- * DOC: basic gatable clock which can gate and ungate it's ouput
- *
- * Traits of this clock:
- * prepare - clk_(un)prepare only ensures parent is (un)prepared
- * enable - clk_enable and clk_disable are functional & control gating
- * rate - inherits rate from parent.  No clk_set_rate support
- * parent - fixed parent.  No clk_set_parent support
