hi ,
I have a doubt about the clk_prepare vs clk_enable.
Currently I see all the users/drivers of clk_enable from process
context in my platform.
There is a bit to write to enable the clocks since clk_enable cannot  sleep
spinlocks are used.
I was thinking since  there is no users can the spinlocks be replaced with
mutex and the function of enabled  be assigned to prepare instead.
However I see similar implementations do option1.
Can clk_prepare also enable the clocks also.
With Regards,
Shubhrajyoti
