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