+description: |
+  MediaTek MIPS and Ralink SoCs provides a system controller to allow
+  to access to system control registers. These registers include clock
+  and reset related ones so this node is both clock and reset provider
+  for the rest of the world.
+
+  These SoCs have an XTAL from where the cpu clock is
+  provided as well as derived clocks for the bus and the peripherals.
