Hi all,

Following patch removes clk_use/unuse for omap, and replaces them with
clk_enable/disable.

The reason for this patch is that omap clock framework has drifted away
from the common arm implementation. Also having the two different set of
functions was confusing.

Generic arm clock framework will remove clk_use/unuse soon, and this
patch makes omap follow the other arm clock framework implementations.

Please comment and test it, I'm planning on pushing it soon. For any new
drivers not yet in our tree the update is minimal. Just replace
clk_use/unuse with clk_enable/disable.

Toshihiro, can you please check the dsp related changes? The problem
there seems to be that the dsp code may enable certain clocks and then
they stay on during suspend.

I've just added clk_enable() clk_disable() in few places there to shut
down any clocks left on from dsp code.

Also, does api_ck_handle reference count work properly in
dsp_cpustat_update()? It seems that clk_enable(api_ck_handle) and
clk_disable(api_ck_handle) may get called multiple times...

Regards,

Tony
