Name
clk_disable — 
     inform the system when the clock source is no longer required.
 
Synopsis
| void clk_disable ( | struct clk * clk ); | 
 
Description
   Inform the system that a clock source is no longer required by
   a driver and may be shut down.
   
   May be called from atomic contexts.
Implementation detail
   if the clock source is shared between
   multiple drivers, clk_enable calls must be balanced by the
   same number of clk_disable calls for the clock source to be
   disabled.
