This patch provides bindings for the 64-bit timer in the KeyStone architecture devices. The timer can be configured as a general-purpose 64-bit timer, dual general-purpose 32-bit timers. When configured as dual 32-bit timers, each half can operate in conjunction (chain mode) or independently (unchained mode) of each other. It is global timer is a free running up-counter and can generate interrupt when the counter reaches preset counter values.
