[Qemu-devel] [PATCH v3 00/10] Clock framework API.

[fred.konrad@greensocs.com]

From: KONRAD Frederic <fred.konrad@greensocs.com>

Hi,

This is the third 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
(d992f2f1368ceb92e6bfd8efece174110f4236ff).

Thanks,
Fred

V2 -> V3:
  * Rebased on current master.
  * Renamed qemu_clk / QEMUClock as suggested by Cédric.
  * Renamed in_rate to ref_rate and out_rate to rate.
  * Renamed qemu_clk_bind_clock to qemu_clk_bind.
  * Example added to the documentation as suggested by Peter.

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
