The Tegra210 timer provides fourteen 29-bit timer counters and one 32-bit
timestamp counter. The TMRs run at either a fixed 1 MHz clock rate derived
from the oscillator clock (TMR0-TMR9) or directly at the oscillator clock
(TMR10-TMR13). Each TMR can be programmed to generate one-shot periodic,
or watchdog interrupts.
