+description: |
+  The clock architecture in MediaTek like below
+  PLLs -->
+          dividers -->
+                      muxes
+                           -->
+                              clock gate
+
+  The apmixedsys provides most of PLLs which generated from SoC 26m.
+  The topckgen provides dividers and muxes which provide the clock source to other IP blocks.
+  The infracfg_ao provides clock gate in peripheral and infrastructure IP blocks.
+  The mcusys provides mux control to select the clock source in AP MCU.
+  The device nodes also provide the system control capacity for configuration.
