Dear RIOT developers,

What are the drawbacks of using a hardware timer with only a 32.768
kHz tick rate?

Would there be any problems with scheduling or hardware drivers when
using a lower timer frequency?

What is the side effect of assigning the hwtimer module only one
hardware timer channel?

As I understand from the code, the hwtimer module uses some kind of
internal queue to be able to handle more timers than there are
hardware channels, is this correct?

On our platform we are using the Freescale Kinetis K60 which has only
one timer (LPTMR) which can wake the CPU from deep sleep. We need to
use deep sleep in order to reduce power consumption in power
constrained situations (battery powered etc.). All other timer modules
in the CPU are halted when the CPU enters a deep sleep mode.
