+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.
