    clocksource/drivers/sysctr: Add nxp system counter timer driver support · 7117a44b
    Bai Ping authored
    The system counter (sys_ctr) is a programmable system counter
    which provides a shared time base to the Cortex A15, A7, A53 etc cores.
    It is intended for use in applications where the counter is always
    powered on and supports multiple, unrelated clocks. The sys_ctr hardware
    supports:
     - 56-bit counter width (roll-over time greater than 40 years)
     - compare frame(64-bit compare value) contains programmable interrupt
       generation when compare value <= counter value.
