[Qemu-devel] [PATCH v5 3/9] qdev-monitor: print the device's clock with info qtree

[Damien Hedde]

This prints the clocks attached to a DeviceState when using "info qtree" monitor
command. For every clock, it displays the direction, the name and if the
clock is forwarded. For input clock, it displays also the frequency.

This is based on the original work of Frederic Konrad.
