Subject: [PATCH 0/8] OPP: Add support for multiple clocks

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.
