12description: |
13  This is a 64-bit timer found on TI's DaVinci architecture devices. The timer
14  can be configured as a general-purpose 64-bit timer, dual general-purpose
15  32-bit timers. When configured as dual 32-bit timers, each half can operate
16  in conjunction (chain mode) or independently (unchained mode) of each other.
17
18  The timer is a free running up-counter and can generate interrupts when the
19  counter reaches preset counter values.
