Hi,
This is a first draft of the clock framework API it contains:
* The first 5 patches which introduce the framework.
* The 6th patch which introduces a fixed-clock model.
* The rest which gives an example how to model a PLL from the existing
zynqmp-crf extracted from the qemu xilinx tree.
No specific behavior is expected yet when the CRF register set is accessed but
the user can see for example the dp_video_ref and vpll_to_lpd rate changing in
the monitor with the "info qtree" command when the vpll_ctrl register is
modified.

This series is based on the current master
(d6550e9ed2e1a60d889dfb721de00d9a4e3bafbe) with the data-driven register
patch-set from Alistair.
Note that the omap clock infrastructure is really far from what we need so I
think it's worse implement the clock framework and then rework the omaps
platforms to use it.
TODO:
* reshape the omap clock tree to use this one.
Any comment on that?
Thanks,
Fred
