The timer was deadlocking when the interval was set too low. It would cause a flood of timer events and the CPU would halt indefinately. This is a known issue and theres a generic workaround in place in ptimer on ptimer_set_limit(), however the Xilinx timer uses ptimer_set_count() instead of set_limit. Changed the call to set_count() to an equivalent call of set_limit() instead, which brings the workaround into play. Signed-off-by: Peter A. G.
