[Qemu-devel] [PATCH V1 00/10] Clock framework API. |

Hi,
This is the first 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
(bbc4c3f4f3c624e2de64fdcb79f4dd8c1a508e9d).
Thanks,
Fred
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 attach 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
