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.
