This clock source we added with a motive of completion, however it's
not being used as of now.
As far as i could see the lookup structure contains clocks for devices
having multiple instances.
Do you feel that i should be adding an entry in clk_lookup structure ?
May be i am missing here something. Can you please elaborate on the
use-case of clk_lookup
entries.
