Hello,

This patchset adds support for device with multiple clocks. None of the clocks
is considered primary in this case and all are handled equally.

This is rebased over a lot of other OPP changes and is pushed here:

git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git opp/clk

Krzysztof, can you please test this for your use case. I wasn't able to test he
multiple clock support.
