Yes it is DT based, but there is no mention of hrtimer in any other dts file. From what I
understand support for hrtimers depends on the driver for the timer used. The ARM
arch timer is used by quite a few boards, so I suspect that the driver supports hrtimers,
just something I am doing wrong.

Nope.
Thanks anyway,
Phil
