Hi,
This is the second version of the clock framework API it contains:
* The first 6 patches which introduce the framework.
* The 7th 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
(a9e404600a9bd1e6a26431fc89e5069092e67f14).
Thanks,
Fred
V1 -> V2:
* Rebased on current master.
* Some function renamed and documentation fixed.
RFC -> V1:
* Rebased on current master.
* The docs has been fixed.
* qemu_clk_init_device helper has been provided to ease the initialization
of the devices.
KONRAD Frederic (10):
qemu-clk: introduce qemu-clk qom object
qemu-clk: allow to add a clock to a device
qemu-clk: allow to bind two clocks together
qemu-clk: introduce an init array to help the device construction
qdev-monitor: print the device's clock with info qtree
docs: add qemu-clock documentation
introduce fixed-clock
introduce zynqmp_crf
zynqmp: add the zynqmp_crf to the platform
zynqmp: add reference clock
