Subject: Re: [PATCH 00/10] clk: mvebu: restructure SoC clock drivers

Thomas, Sebastian,

In order to avoid losing changes between this series and mvebu/pcie,
I've rebased this series on top of mvebu/pcie and incorporated the
correct conflict resolution into this series.  See below...

I updated armada_370_gating_descr[] and armada_xp_gating_descr[] to
incorporate Thomas' pcie changes.

I then migrated the changes above to these two commits.

Obviously, the diffstat changed slightly here.

I'm posting the revised version as replies to patches 1, 5 and 6. Please
let me know if I messed it up.  I'd like to send the PR for these
shortly.

thx,

Jason.
