Marc Zyngier 985c0679df arm64: Generic timers support ... This patch adds support for the ARM generic timers with A64 instructions for accessing the timer registers. It uses the physical counter as the clock source and the virtual counter as sched_clock. The timer frequency can be specified via DT or read from the CNTFRQ_EL0 register. The physical counter is also accessible from user space allowing fast gettimeofday() implementation.
