*****************************************************************************

"qcom,ext-clk"

A logical entity representing a clock defined outside of the current clock controller.

A clock controller can only manage ordering dependencies within itself. Having an

ext_clk whose parent is the actual external clock allows us to initialize the

necessary clock data structures with the assumption that the missing dependency will

be filled in later. During __handoff() this clock type will call clk_get() to fix the

dependency.

Required Properties:

- compatible:		Must be "qcom,ext-clk"

Optional Properties:

- qcom,clock-names:	String argument for clk_get().

Recommended Properties:

- qcom,parent:		See "General Optional Properties"
