13  The system counter(sys_ctr) is a programmable system counter
14  which provides a shared time base to Cortex A15, A7, A53, A73,
15  etc. it is intended for use in applications where the counter
16  is always powered and support multiple, unrelated clocks. The
17  compare frame inside can be used for timer purpose.
