RE: REG: TTC Timer

[Konrad, Frederic]

Hi Philippe,
Hi Gowri,

The zcu102 has a zynqmp soc object (hw/arm/xlnx-zcu102.c:125):

static void xlnx_zcu102_init(MachineState *machine)
{
...
    object_initialize_child(OBJECT(machine), "soc", &s->soc, TYPE_XLNX_ZYNQMP);

So the TTCs should work in the ZCU102.

Best Regards,
Fred
