title: MTMIPS SoCs System Controller

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.
